The names have to be quoted with a pair of -single quotes. Examples are 'func (int, long)' and 'obj::operator==(obj&)'. -Make use of command completion, it is your friend. - -GDB also now accepts a variety of C++ mangled symbol formats. They are -the GNU g++ style, the Cfront (ARM) style, and the Lucid (lcc) style. -You can tell GDB which format to use by doing a 'set demangle-style {gnu, -lucid, cfront, auto}'. 'gnu' is the default. Do a 'set demangle-style foo' -for the list of formats. - - * G++ symbol mangling problem - -Recent versions of gcc have a bug in how they emit debugging information for -C++ methods (when using dbx-style stabs). The file 'gcc.patch' (in this -directory) can be applied to gcc to fix the problem. Alternatively, if you -can't fix gcc, you can #define GCC_MANGLE_BUG when compling gdb/symtab.c. The -usual symptom is difficulty with setting breakpoints on methods. GDB complains -about the method being non-existent. (We believe that version 2.2.2 of GCC has -this problem.) - - * New 'maintenance' command - -All of the commands related to hacking GDB internals have been moved out of -the main command set, and now live behind the 'maintenance' command. This -can also be abbreviated as 'mt'. The following changes were made: - - dump-me -> maintenance dump-me - info all-breakpoints -> maintenance info breakpoints - printmsyms -> maintenance print msyms - printobjfiles -> maintenance print objfiles - printpsyms -> maintenance print psymbols - printsyms -> maintenance print symbols - -The following commands are new: - - maintenance demangle Call internal GDB demangler routine to - demangle a C++ link name and prints the result. - maintenance print type Print a type chain for a given symbol - - * Change to .gdbinit file processing - -We now read the $HOME/.gdbinit file before processing the argv arguments -(e.g. reading symbol files or core files). This allows global parameters to -be set, which will apply during the symbol reading. The ./.gdbinit is still -read after argv processing. - - * New hosts supported - -Solaris-2.0 !!! sparc-sun-solaris2 or sun4sol2 - -Linux support i386-unknown-linux or linux - -We are also including code to support the HP/PA running BSD and HPUX. This -is almost guaranteed not to work, as we didn't have time to test or build it -for this release. We are including it so that the more adventurous (or -masochistic) of you can play with it. We also had major problems with the -fact that the compiler that we got from HP doesn't support the -g option. -It costs extra. - - * New targets supported - -Hitachi H8/300 h8300-hitachi-hms or h8300hms - - * More smarts about finding #include files - -GDB now remembers the compilation directory for all include files, and for -all files from which C is generated (like yacc and lex sources). This -greatly improves GDB's ability to find yacc/lex sources, and include files, -especially if you are debugging your program from a directory different from -the one that contains your sources. - -We also fixed a bug which caused difficulty with listing and setting -breakpoints in include files which contain C code. (In the past, you had to -try twice in order to list an include file that you hadn't looked at before.) - - * Interesting infernals change - -GDB now deals with arbitrary numbers of sections, where the symbols for each -section must be relocated relative to that section's landing place in the -target's address space. This work was needed to support ELF with embedded -stabs used by Solaris-2.0. - - * Bug fixes (of course!) - -There have been loads of fixes for the following things: - mips, rs6000, 29k/udi, m68k, g++, type handling, elf/dwarf, m88k, - i960, stabs, DOS(GO32), procfs, etc... - -See the ChangeLog for details. - -*** Changes in GDB-4.5: - - * New machines supported (host and target) - -IBM RS6000 running AIX rs6000-ibm-aix or rs6000 - -SGI Irix-4.x mips-sgi-irix4 or iris4 - - * New malloc package - -GDB now uses a new memory manager called mmalloc, based on gmalloc. -Mmalloc is capable of handling mutiple heaps of memory. It is also -capable of saving a heap to a file, and then mapping it back in later. -This can be used to greatly speedup the startup of GDB by using a -pre-parsed symbol table which lives in a mmalloc managed heap. For -more details, please read mmalloc/mmalloc.texi. - - * info proc - -The 'info proc' command (SVR4 only) has been enhanced quite a bit. See -'help info proc' for details. - - * MIPS ecoff symbol table format - -The code that reads MIPS symbol table format is now supported on all hosts. -Thanks to MIPS for releasing the sym.h and symconst.h files to make this -possible. - - * File name changes for MS-DOS - -Many files in the config directories have been renamed to make it easier to -support GDB on MS-DOSe systems (which have very restrictive file name -conventions :-( ). MS-DOSe host support (under DJ Delorie's GO32 -environment) is close to working but has some remaining problems. Note -that debugging of DOS programs is not supported, due to limitations -in the ``operating system'', but it can be used to host cross-debugging. - - * Cross byte order fixes - -Many fixes have been made to support cross debugging of Sparc and MIPS -targets from hosts whose byte order differs. - - * New -mapped and -readnow options - -If memory-mapped files are available on your system through the 'mmap' -system call, you can use the -mapped option on the `file' or -`symbol-file' commands to cause GDB to write the symbols from your -program into a reusable file. If the program you are debugging is -called `/path/fred', the mapped symbol file will be `./fred.syms'. -Future GDB debugging sessions will notice the presence of this file, -and will quickly map in symbol information from it, rather than reading -the symbol table from the executable program. Using the '-mapped' -option in a GDB `file' or `symbol-file' command has the same effect as -starting GDB with the '-mapped' command-line option. - -You can cause GDB to read the entire symbol table immediately by using -the '-readnow' option with any of the commands that load symbol table -information (or on the GDB command line). This makes the command -slower, but makes future operations faster. - -The -mapped and -readnow options are typically combined in order to -build a `fred.syms' file that contains complete symbol information. -A simple GDB invocation to do nothing but build a `.syms' file for future -use is: - - gdb -batch -nx -mapped -readnow programname - -The `.syms' file is specific to the host machine on which GDB is run. -It holds an exact image of GDB's internal symbol table. It cannot be -shared across multiple host platforms. - - * longjmp() handling - -GDB is now capable of stepping and nexting over longjmp(), _longjmp(), and -siglongjmp() without losing control. This feature has not yet been ported to -all systems. It currently works on many 386 platforms, all MIPS-based -platforms (SGI, DECstation, etc), and Sun3/4. - - * Solaris 2.0 - -Preliminary work has been put in to support the new Solaris OS from Sun. At -this time, it can control and debug processes, but it is not capable of -reading symbols. - - * Bug fixes - -As always, many many bug fixes. The major areas were with g++, and mipsread. -People using the MIPS-based platforms should experience fewer mysterious -crashes and trashed symbol tables. - -*** Changes in GDB-4.4: - - * New machines supported (host and target) - -SCO Unix on i386 IBM PC clones i386-sco-sysv or i386sco - (except core files) -BSD Reno on Vax vax-dec-bsd -Ultrix on Vax vax-dec-ultrix - - * New machines supported (target) - -AMD 29000 embedded, using EBMON a29k-none-none - - * C++ support - -GDB continues to improve its handling of C++. `References' work better. -The demangler has also been improved, and now deals with symbols mangled as -per the Annotated C++ Reference Guide. - -GDB also now handles `stabs' symbol information embedded in MIPS -`ecoff' symbol tables. Since the ecoff format was not easily -extensible to handle new languages such as C++, this appeared to be a -good way to put C++ debugging info into MIPS binaries. This option -will be supported in the GNU C compiler, version 2, when it is -released. - - * New features for SVR4 - -GDB now handles SVR4 shared libraries, in the same fashion as SunOS -shared libraries. Debugging dynamically linked programs should present -only minor differences from debugging statically linked programs. - -The `info proc' command will print out information about any process -on an SVR4 system (including the one you are debugging). At the moment, -it prints the address mappings of the process. - -If you bring up GDB on another SVR4 system, please send mail to -bug-gdb@prep.ai.mit.edu to let us know what changes were reqired (if any). - - * Better dynamic linking support in SunOS - -Reading symbols from shared libraries which contain debugging symbols -now works properly. However, there remain issues such as automatic -skipping of `transfer vector' code during function calls, which -make it harder to debug code in a shared library, than to debug the -same code linked statically. - - * New Getopt - -GDB is now using the latest `getopt' routines from the FSF. This -version accepts the -- prefix for options with long names. GDB will -continue to accept the old forms (-option and +option) as well. -Various single letter abbreviations for options have been explicity -added to the option table so that they won't get overshadowed in the -future by other options that begin with the same letter. - - * Bugs fixed - -The `cleanup_undefined_types' bug that many of you noticed has been squashed. -Many assorted bugs have been handled. Many more remain to be handled. -See the various ChangeLog files (primarily in gdb and bfd) for details. - - -*** Changes in GDB-4.3: - - * New machines supported (host and target) - -Amiga 3000 running Amix m68k-cbm-svr4 or amix -NCR 3000 386 running SVR4 i386-ncr-svr4 or ncr3000 -Motorola Delta 88000 running Sys V m88k-motorola-sysv or delta88 - - * Almost SCO Unix support - -We had hoped to support: -SCO Unix on i386 IBM PC clones i386-sco-sysv or i386sco -(except for core file support), but we discovered very late in the release -that it has problems with process groups that render gdb unusable. Sorry -about that. I encourage people to fix it and post the fixes. - - * Preliminary ELF and DWARF support - -GDB can read ELF object files on System V Release 4, and can handle -debugging records for C, in DWARF format, in ELF files. This support -is preliminary. If you bring up GDB on another SVR4 system, please -send mail to bug-gdb@prep.ai.mit.edu to let us know what changes were -reqired (if any). - - * New Readline - -GDB now uses the latest `readline' library. One user-visible change -is that two tabs will list possible command completions, which previously -required typing M-? (meta-question mark, or ESC ?). - - * Bugs fixed - -The `stepi' bug that many of you noticed has been squashed. -Many bugs in C++ have been handled. Many more remain to be handled. -See the various ChangeLog files (primarily in gdb and bfd) for details. - - * State of the MIPS world (in case you wondered): - -GDB can understand the symbol tables emitted by the compilers -supplied by most vendors of MIPS-based machines, including DEC. These -symbol tables are in a format that essentially nobody else uses. - -Some versions of gcc come with an assembler post-processor called -mips-tfile. This program is required if you want to do source-level -debugging of gcc-compiled programs. I believe FSF does not ship -mips-tfile with gcc version 1, but it will eventually come with gcc -version 2. - -Debugging of g++ output remains a problem. g++ version 1.xx does not -really support it at all. (If you're lucky, you should be able to get -line numbers and stack traces to work, but no parameters or local -variables.) With some work it should be possible to improve the -situation somewhat. - -When gcc version 2 is released, you will have somewhat better luck. -However, even then you will get confusing results for inheritance and -methods. - -We will eventually provide full debugging of g++ output on -DECstations. This will probably involve some kind of stabs-in-ecoff -encapulation, but the details have not been worked out yet. - - -*** Changes in GDB-4.2: - - * Improved configuration - -Only one copy of `configure' exists now, and it is not self-modifying. -Porting BFD is simpler. - - * Stepping improved - -The `step' and `next' commands now only stop at the first instruction -of a source line. This prevents the multiple stops that used to occur -in switch statements, for-loops, etc. `Step' continues to stop if a -function that has debugging information is called within the line. - - * Bug fixing - -Lots of small bugs fixed. More remain. - - * New host supported (not target) - -Intel 386 PC clone running Mach i386-none-mach - - -*** Changes in GDB-4.1: - - * Multiple source language support - -GDB now has internal scaffolding to handle several source languages. -It determines the type of each source file from its filename extension, -and will switch expression parsing and number formatting to match the -language of the function in the currently selected stack frame. -You can also specifically set the language to be used, with -`set language c' or `set language modula-2'. - - * GDB and Modula-2 - -GDB now has preliminary support for the GNU Modula-2 compiler, -currently under development at the State University of New York at -Buffalo. Development of both GDB and the GNU Modula-2 compiler will -continue through the fall of 1991 and into 1992. - -Other Modula-2 compilers are currently not supported, and attempting to -debug programs compiled with them will likely result in an error as the -symbol table is read. Feel free to work on it, though! - -There are hooks in GDB for strict type checking and range checking, -in the `Modula-2 philosophy', but they do not currently work. - - * set write on/off - -GDB can now write to executable and core files (e.g. patch -a variable's value). You must turn this switch on, specify -the file ("exec foo" or "core foo"), *then* modify it, e.g. -by assigning a new value to a variable. Modifications take -effect immediately. - - * Automatic SunOS shared library reading - -When you run your program, GDB automatically determines where its -shared libraries (if any) have been loaded, and reads their symbols. -The `share' command is no longer needed. This also works when -examining core files. - - * set listsize - -You can specify the number of lines that the `list' command shows. -The default is 10. - - * New machines supported (host and target) - -SGI Iris (MIPS) running Irix V3: mips-sgi-irix or iris -Sony NEWS (68K) running NEWSOS 3.x: m68k-sony-sysv or news -Ultracomputer (29K) running Sym1: a29k-nyu-sym1 or ultra3 - - * New hosts supported (not targets) - -IBM RT/PC: romp-ibm-aix or rtpc - - * New targets supported (not hosts) - -AMD 29000 embedded with COFF a29k-none-coff -AMD 29000 embedded with a.out a29k-none-aout -Ultracomputer remote kernel debug a29k-nyu-kern - - * New remote interfaces - -AMD 29000 Adapt -AMD 29000 Minimon - - -*** Changes in GDB-4.0: - - * New Facilities - -Wide output is wrapped at good places to make the output more readable. - -Gdb now supports cross-debugging from a host machine of one type to a -target machine of another type. Communication with the target system -is over serial lines. The ``target'' command handles connecting to the -remote system; the ``load'' command will download a program into the -remote system. Serial stubs for the m68k and i386 are provided. Gdb -also supports debugging of realtime processes running under VxWorks, -using SunRPC Remote Procedure Calls over TCP/IP to talk to a debugger -stub on the target system. - -New CPUs supported include the AMD 29000 and Intel 960. - -GDB now reads object files and symbol tables via a ``binary file'' -library, which allows a single copy of GDB to debug programs of multiple -object file types such as a.out and coff. - -There is now a GDB reference card in "doc/refcard.tex". (Make targets -refcard.dvi and refcard.ps are available to format it). - - - * Control-Variable user interface simplified - -All variables that control the operation of the debugger can be set -by the ``set'' command, and displayed by the ``show'' command. - -For example, ``set prompt new-gdb=>'' will change your prompt to new-gdb=>. -``Show prompt'' produces the response: -Gdb's prompt is new-gdb=>. - -What follows are the NEW set commands. The command ``help set'' will -print a complete list of old and new set commands. ``help set FOO'' -will give a longer description of the variable FOO. ``show'' will show -all of the variable descriptions and their current settings. - -confirm on/off: Enables warning questions for operations that are - hard to recover from, e.g. rerunning the program while - it is already running. Default is ON. - -editing on/off: Enables EMACS style command line editing - of input. Previous lines can be recalled with - control-P, the current line can be edited with control-B, - you can search for commands with control-R, etc. - Default is ON. - -history filename NAME: NAME is where the gdb command history - will be stored. The default is .gdb_history, - or the value of the environment variable - GDBHISTFILE. - -history size N: The size, in commands, of the command history. The - default is 256, or the value of the environment variable - HISTSIZE. - -history save on/off: If this value is set to ON, the history file will - be saved after exiting gdb. If set to OFF, the - file will not be saved. The default is OFF. - -history expansion on/off: If this value is set to ON, then csh-like - history expansion will be performed on - command line input. The default is OFF. - -radix N: Sets the default radix for input and output. It can be set - to 8, 10, or 16. Note that the argument to "radix" is interpreted - in the current radix, so "set radix 10" is always a no-op. - -height N: This integer value is the number of lines on a page. Default - is 24, the current `stty rows'' setting, or the ``li#'' - setting from the termcap entry matching the environment - variable TERM. - -width N: This integer value is the number of characters on a line. - Default is 80, the current `stty cols'' setting, or the ``co#'' - setting from the termcap entry matching the environment - variable TERM. - -Note: ``set screensize'' is obsolete. Use ``set height'' and -``set width'' instead. - -print address on/off: Print memory addresses in various command displays, - such as stack traces and structure values. Gdb looks - more ``symbolic'' if you turn this off; it looks more - ``machine level'' with it on. Default is ON. - -print array on/off: Prettyprint arrays. New convenient format! Default - is OFF. - -print demangle on/off: Print C++ symbols in "source" form if on, - "raw" form if off. - -print asm-demangle on/off: Same, for assembler level printouts - like instructions. - -print vtbl on/off: Prettyprint C++ virtual function tables. Default is OFF. - - - * Support for Epoch Environment. - -The epoch environment is a version of Emacs v18 with windowing. One -new command, ``inspect'', is identical to ``print'', except that if you -are running in the epoch environment, the value is printed in its own -window. - - - * Support for Shared Libraries - -GDB can now debug programs and core files that use SunOS shared libraries. -Symbols from a shared library cannot be referenced -before the shared library has been linked with the program (this -happens after you type ``run'' and before the function main() is entered). -At any time after this linking (including when examining core files -from dynamically linked programs), gdb reads the symbols from each -shared library when you type the ``sharedlibrary'' command. -It can be abbreviated ``share''. - -sharedlibrary REGEXP: Load shared object library symbols for files - matching a unix regular expression. No argument - indicates to load symbols for all shared libraries. - -info sharedlibrary: Status of loaded shared libraries. - - - * Watchpoints - -A watchpoint stops execution of a program whenever the value of an -expression changes. Checking for this slows down execution -tremendously whenever you are in the scope of the expression, but is -quite useful for catching tough ``bit-spreader'' or pointer misuse -problems. Some machines such as the 386 have hardware for doing this -more quickly, and future versions of gdb will use this hardware. - -watch EXP: Set a watchpoint (breakpoint) for an expression. - -info watchpoints: Information about your watchpoints. - -delete N: Deletes watchpoint number N (same as breakpoints). -disable N: Temporarily turns off watchpoint number N (same as breakpoints). -enable N: Re-enables watchpoint number N (same as breakpoints). - - - * C++ multiple inheritance - -When used with a GCC version 2 compiler, GDB supports multiple inheritance -for C++ programs. - - * C++ exception handling - -Gdb now supports limited C++ exception handling. Besides the existing -ability to breakpoint on an exception handler, gdb can breakpoint on -the raising of an exception (before the stack is peeled back to the -handler's context). - -catch FOO: If there is a FOO exception handler in the dynamic scope, - set a breakpoint to catch exceptions which may be raised there. - Multiple exceptions (``catch foo bar baz'') may be caught. - -info catch: Lists all exceptions which may be caught in the - current stack frame. - - - * Minor command changes - -The command ``call func (arg, arg, ...)'' now acts like the print -command, except it does not print or save a value if the function's result -is void. This is similar to dbx usage. - -The ``up'' and ``down'' commands now always print the frame they end up -at; ``up-silently'' and `down-silently'' can be used in scripts to change -frames without printing. - - * New directory command - -'dir' now adds directories to the FRONT of the source search path. -The path starts off empty. Source files that contain debug information -about the directory in which they were compiled can be found even -with an empty path; Sun CC and GCC include this information. If GDB can't -find your source file in the current directory, type "dir .". - - * Configuring GDB for compilation - -For normal use, type ``./configure host''. See README or gdb.texinfo -for more details. - -GDB now handles cross debugging. If you are remotely debugging between -two different machines, type ``./configure host -target=targ''. -Host is the machine where GDB will run; targ is the machine -where the program that you are debugging will run. diff --git a/gdb/a68v-xdep.c b/gdb/a68v-xdep.c index d81cbe8..e69de29 100644 --- a/gdb/a68v-xdep.c +++ b/gdb/a68v-xdep.c @@ -1,158 +0,0 @@ -/* Host-dependent code for Apollo-68ksfor GDB, the GNU debugger. - Copyright 1986, 1987, 1989, 1991 Free Software Foundation, Inc. - -This file is part of GDB. - -This program is free software; you can redistribute it and/or modify -it under the terms of the GNU General Public License as published by -the Free Software Foundation; either version 2 of the License, or -(at your option) any later version. - -This program is distributed in the hope that it will be useful, -but WITHOUT ANY WARRANTY; without even the implied warranty of -MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

-@item -Make your program stop on specified conditions. - -@item -Examine what has happened, when your program has stopped. - -@item -Change things in your program, so you can experiment with correcting the -effects of one bug and go on to learn about another. -@end itemize - -You can use GDB to debug programs written in C, C++, and Modula-2. -Fortran support will be added when a GNU Fortran compiler is ready. - -@menu -* Free Software:: Free Software -* Contributors:: Contributors to GDB -@end menu -

As major maintainer of GDB for some -period, each contributed significantly to the structure, stability, and -capabilities of the entire debugger. - -Richard Stallman, assisted at various times by Pete TerMaat, Chris -Hanson, and Richard Mlynarik, handled releases through 2.8. - -Michael Tiemann is the author of most of the GNU C++ support in GDB, -with significant additional contributions from Per Bothner. James -Clark wrote the GNU C++ demangler. Early work on C++ was by Peter -TerMaat (who also did much general update work leading to release 3.0). - -GDB 4 uses the BFD subroutine library to examine multiple -object-file formats; BFD was a joint project of David V. -Henkel-Wallace, Rich Pixley, Steve Chamberlain, and John Gilmore. - -David Johnson wrote the original COFF support; Pace Willison did -the original support for encapsulated COFF. - -Adam de Boor and Bradley Davis contributed the ISI Optimum V support. -Per Bothner, Noboyuki Hikichi, and Alessandro Forin contributed MIPS -support. Jean-Daniel Fekete contributed Sun 386i support. Chris -Hanson improved the HP9000 support. Noboyuki Hikichi and Tomoyuki -Hasei contributed Sony/News OS 3 support. David Johnson contributed -Encore Umax support. Jyrki Kuoppala contributed Altos 3068 support. -Keith Packard contributed NS32K support. Doug Rabson contributed -Acorn Risc Machine support. Chris Smith contributed Convex support -(and Fortran debugging). Jonathan Stone contributed Pyramid support. -Michael Tiemann contributed SPARC support. Tim Tucker contributed -support for the Gould NP1 and Gould Powernode. Pace Willison -contributed Intel 386 support. Jay Vosburgh contributed Symmetry -support. - -Rich Schaefer and Peter Schauer helped with support of SunOS shared -libraries. - -Jay Fenlason and Roland McGrath ensured that GDB and GAS agree about -several machine instruction sets. - -Patrick Duval, Ted Goldstein, Vikram Koka and Glenn Engel helped -develop remote debugging. Intel Corporation and Wind River Systems -contributed remote debugging modules for their products. - -Brian Fox is the author of the readline libraries providing -command-line editing and command history. - -Andrew Beers of SUNY Buffalo wrote the language-switching code and -the Modula-2 support, and contributed the Languages chapter of this -manual. - -@node New Features, Sample Session, Summary, Top -@unnumbered New Features since GDB version 3.5 - -@table @emph -@item Targets -Using the new command @code{target}, you can select at runtime whether -you are debugging local files, local processes, standalone systems over -a serial port, realtime systems over a TCP/IP connection, etc. The -command @code{load} can download programs into a remote system. Serial -stubs are available for Motorola 680x0 and Intel 80386 remote systems; -GDB also supports debugging realtime processes running under -VxWorks, using SunRPC Remote Procedure Calls over TCP/IP to talk to a -debugger stub on the target system. Internally, GDB now uses a -function vector to mediate access to different targets; if you need to -add your own support for a remote protocol, this makes it much easier. - -@item Watchpoints -GDB now sports watchpoints as well as breakpoints. You can use a -watchpoint to stop execution whenever the value of an expression -changes, without having to predict a particular place in your program -where this may happen. - -@item Wide Output -Commands that issue wide output now insert newlines at places designed -to make the output more readable. - -@item Object Code Formats -GDB uses a new library called the Binary File Descriptor (BFD) -Library to permit it to switch dynamically, without reconfiguration or -recompilation, between different object-file formats. Formats currently -supported are COFF, a.out, and the Intel 960 b.out; files may be read as -.o's, archive libraries, or core dumps. BFD is available as a -subroutine library so that other programs may take advantage of it, and -the other GNU binary utilities are being converted to use it. - -@item Configuration and Ports -Compile-time configuration (to select a particular architecture and -operating system) is much easier. The script @code{configure} now -allows you to configure GDB as either a native debugger or a -cross-debugger. @xref{Installing GDB}, for details on how to -configure and on what architectures are now available. - -@item Interaction -The user interface to GDB's control variables has been simplified -and consolidated in two commands, @code{set} and @code{show}. Output -lines are now broken at readable places, rather than overflowing onto -the next line. You can suppress output of machine-level addresses, -displaying only source language information. - -@item C++ -GDB now supports C++ multiple inheritance (if used with a GCC -version 2 compiler), and also has limited support for C++ exception -handling, with the commands @code{catch} and @code{info catch}: GDB -can break when an exception is raised, before the stack is peeled back -to the exception handler's context. - -@item Modula-2 -GDB now has preliminary support for the GNU Modula-2 compiler, -currently under development at the State University of New York at -Buffalo. Coordinated development of both GDB and the GNU Modula-2 -compiler will continue into 1992. Other Modula-2 compilers are -currently not supported, and attempting to debug programs compiled with -them will likely result in an error as the symbol table of the -executable is read in. - -@item Command Rationalization -Many GDB commands have been renamed to make them easier to remember -and use. In particular, the subcommands of @code{info} and -@code{show}/@code{set} are grouped to make the former refer to the state -of your program, and the latter refer to the state of GDB itself. -@xref{Renamed Commands}, for details on what commands were renamed. - -@item Shared Libraries -GDB 4 can debug programs and core files that use SunOS shared -libraries. - -@item Reference Card -GDB 4 has a reference card. @xref{Formatting Documentation} for -instructions on printing it. - -@item Work in Progress -Kernel debugging for BSD and Mach systems; Tahoe and HPPA architecture -support. -@end table - -@node Sample Session, Invocation, New Features, Top -@chapter A Sample GDB Session - -You can use this manual at your leisure to read all about GDB. -However, a handful of commands are enough to get started using the -debugger. This chapter illustrates these commands. - -@iftex -In this sample session, we emphasize user input like this: @i{input}, -to make it easier to pick out from the surrounding output. -@end iftex - -@c FIXME: this example may not be appropriate for some configs, where -@c FIXME...primary interest is in remote use. - -One of the preliminary versions of GNU @code{m4} (a generic macro -processor) exhibits the following bug: sometimes, when we change its -quote strings from the default, the commands used to capture one macro's -definition in another stop working. In the following short @code{m4} -session, we define a macro @code{foo} which expands to @code{0000}; we -then use the @code{m4} built-in @code{defn} to define @code{bar} as the -same thing.

Give the -executable file you want to debug as an argument. This command starts -GDB as a subprocess of Emacs, with input and output through a newly -created Emacs buffer. - -Using GDB under Emacs is just like using GDB normally except for two -things: - -@itemize @bullet -@item -All ``terminal'' input and output goes through the Emacs buffer. -@end itemize - -This applies both to GDB commands and their output, and to the input -and output done by the program you are debugging. - -This is useful because it means that you can copy the text of previous -commands and input them again; you can even use parts of the output -in this way. - -All the facilities of Emacs' Shell mode are available for interacting -with your program. In particular, you can send signals the usual -way---for example, @kbd{C-c C-c} for an interrupt, @kbd{C-c C-z} for a -stop. - -@itemize @bullet -@item -GDB displays source code through Emacs. -@end itemize - -Each time GDB displays a stack frame, Emacs automatically finds the -source file for that frame and puts an arrow (@samp{=>}) at the -left margin of the current line.

GDB can find programs by searching your -environment's @code{PATH} variable, so the GDB input and output -session will proceed normally; but Emacs does not get enough information -back from GDB to locate the source files in this situation. To -avoid this problem, either start GDB mode from the directory where -your program resides, or specify a full path name when prompted for the -@kbd{M-x gdb} argument. - -A similar confusion can result if you use the GDB @code{file} command to -switch to debugging a program in some other location, from an existing -GDB buffer in Emacs. -@end quotation - -By default, @kbd{M-x gdb} calls the program called @file{gdb}.

A numeric argument to @kbd{C-x &} will both indicate that you -wish special formatting, and act as an index to pick an element of the -list.

Those that do, have arranged to receive @samp{bug-gdb}. - -The mailing list @samp{bug-gdb} has a newsgroup @samp{gnu.gdb.bug} which -serves as a repeater. The mailing list and the newsgroup carry exactly -the same messages. Often people think of posting bug reports to the -newsgroup instead of mailing them. This appears to work, but it has one -problem which can be crucial: a newsgroup posting often lacks a mail -path back to the sender. Thus, if we need to ask for more information, -we may be unable to reach you. For this reason, it is better to send -bug reports to the mailing list. - -As a last resort, send bug reports on paper to: - -@example -GNU Debugger Bugs -Free Software Foundation -545 Tech Square -Cambridge, MA 02139 -@end example - -The fundamental principle of reporting bugs usefully is this: -@strong{report all the facts}. If you are not sure whether to state a -fact or leave it out, state it! - -Often people omit facts because they think they know what causes the -problem and assume that some details do not matter. Thus, you might -assume that the name of the variable you use in an example does not matter. -Well, probably it does not, but one cannot be sure. Perhaps the bug is a -stray memory reference which happens to fetch from the location where that -name is stored in memory; perhaps, if the name were different, the contents -of that location would fool the debugger into doing the right thing despite -the bug. Play it safe and give a specific, complete example. That is the -easiest thing for you to do, and the most helpful. - -Keep in mind that the purpose of a bug report is to enable us to fix -the bug if it is new to us. It is not as important as what happens if -the bug is already known. Therefore, always write your bug reports on -the assumption that the bug has not been reported previously. - -Sometimes people give a few sketchy facts and ask, ``Does this ring a -bell?'' Those bug reports are useless, and we urge everyone to -@emph{refuse to respond to them} except to chide the sender to report -bugs properly. - -To enable us to fix the bug, you should include all these things: - -@itemize @bullet -@item -The version of GDB. GDB announces it if you start with no -arguments; you can also print it at any time using @code{show version}. - -Without this, we will not know whether there is any point in looking for -the bug in the current version of GDB. - -@item -The type of machine you are using, and the operating system name and -version number. - -@item -What compiler (and its version) was used to compile GDB---e.g. -``gcc-2.0''. - -@item -What compiler (and its version) was used to compile the program you -are debugging---e.g. ``gcc-2.0''. - -@item -The command arguments you gave the compiler to compile your example and -observe the bug. For example, did you use @samp{-O}? To guarantee -you will not omit something important, list them all. A copy of the -Makefile (or the output from make) is sufficient. - -If we were to try to guess the arguments, we would probably guess wrong -and then we might not encounter the bug. - -@item -A complete input script, and all necessary source files, that will -reproduce the bug. - -@item -A description of what behavior you observe that you believe is -incorrect. For example, ``It gets a fatal signal.'' - -Of course, if the bug is that GDB gets a fatal signal, then we will -certainly notice it. But if the bug is incorrect output, we might not -notice unless it is glaringly wrong. We are human, after all.

Suppose something strange is going on, such as, -your copy of GDB is out of synch, or you have encountered a -bug in the C library on your system. (This has happened!) Your copy -might crash and ours would not. If you told us to expect a crash, -then when ours fails to crash, we would know that the bug was not -happening for us.

But do not omit -the necessary information, such as the test case, on the assumption that -a patch is all we need. We might see problems with your patch and decide -to fix the problem another way, or we might not understand it at all. - -Sometimes with a program as complicated as GDB it is very hard to -construct an example that will make the program follow a certain path -through the code. If you do not send us the example, we will not be able -to construct one, so we will not be able to verify that the bug is fixed. - -And if we cannot understand what bug you are trying to fix, or why your -patch should be an improvement, we will not install it.

If -identifiable sections of that work are not derived from the Program, -and can be reasonably considered independent and separate works in -themselves, then this License, and its terms, do not apply to those -sections when you distribute them as separate works.

Also, since breakpoints are active during -stepping, your program will stop for them even if it has not gone as far -as the stepping command specifies.} - -A typical technique for using stepping is to put a breakpoint -(@pxref{Breakpoints}) at the beginning of the function or the section of -the program in which a problem is believed to lie, run the program until -it stops at that breakpoint, and then step through the suspect area, -examining the variables that are interesting, until you see the problem -happen. - -@table @code -@item step -@kindex step -@kindex s -Continue running the program until control reaches a different source -line, then stop it and return control to the debugger. This command is -abbreviated @code{s}. - -You may use the @code{step} command when control is within a function -for which there is no debugging information. In that case, execution -will proceed until control reaches a different function, or is about to -return from this function. - -@item step @var{count} -Continue running as in @code{step}, but do so @var{count} times. If a -breakpoint is reached or a signal not related to stepping occurs before -@var{count} steps, stepping stops right away. - -@item next -@kindex next -@kindex n -Continue to the next source line in the current stack frame. Similar to -@code{step}, but any function calls appearing within the line of code -are executed without stopping. Execution stops when control reaches a -different line of code at the stack level which was executing when the -@code{next} command was given. This command is abbreviated @code{n}. - -An argument is a repeat count, as in @code{step}. - -@code{next} within a function that lacks debugging information acts like -@code{step}, but any function calls appearing within the code of the -function are executed without stopping. - -@item finish -@kindex finish -Continue running until just after the selected stack frame returns (or -until there is some other reason to stop, such as a fatal signal or a -breakpoint).

This command is used to avoid single -stepping through a loop more than once. It is like the @code{next} -command, except that when @code{until} encounters a jump, it -automatically continues execution until the program counter is greater -than the address of the jump. - -This means that when you reach the end of a loop after single stepping -though it, @code{until} will cause the program to continue execution -until the loop is exited. In contrast, a @code{next} command at the end -of a loop will simply step back to the beginning of the loop, which -would force you to step through the next iteration. - -@code{until} always stops the program if it attempts to exit the current -stack frame. - -@code{until} may produce somewhat counterintuitive results if the order -of the source lines does not match the actual order of execution. For -example, in the following excerpt from a debugging session, the @code{f} -(@code{frame}) command shows that execution is stopped at line -@code{206}; yet when we use @code{until}, we get to line @code{195}: - -@example -(_GDBP__) f -#0 main (argc=4, argv=0xf7fffae8) at m4.c:206 -206 expand_input(); -(_GDBP__) until -195 for ( ; argc > 0; NEXTARG) @{ -@end example - -In this case, (as for any C @code{for}-loop), the loop-step expression -(here, @samp{argc > 0}) is executed @emph{after} the statements in the -body of the loop, but is written before them. Therefore, the -@code{until} command appeared to step back to the beginning of the loop -when it advanced to this expression. However, it has not really gone to -an earlier statement---not in terms of the actual machine code. - -@code{until} with no argument works by means of single -instruction stepping, and hence is slower than @code{until} with an -argument. - -@item until @var{location} -@item u @var{location} -Continue running the program until either the specified location is -reached, or the current (innermost) stack frame returns. @var{location} -is any of the forms of argument acceptable to @code{break} (@pxref{Set -Breaks}).

-@node Summary, New Features, Top, Top -@unnumbered Summary of _GDBN__ - -The purpose of a debugger such as _GDBN__ is to allow you to see what is -going on ``inside'' another program while it executes---or what another -program was doing at the moment it crashed. - -_GDBN__ can do four main kinds of things (plus other things in support of -these) to help you catch bugs in the act: - -@itemize @bullet -@item -Start your program, specifying anything that might affect its behavior. - -@item -Make your program stop on specified conditions. - -@item -Examine what has happened, when your program has stopped. - -@item -Change things in your program, so you can experiment with correcting the -effects of one bug and go on to learn about another. -@end itemize - -_GDBN__ can be used to debug programs written in C and C++. Pascal support -is being implemented, and Fortran support will be added when a GNU -Fortran compiler is ready. - -@menu -* Free Software:: Free Software -* Contributors:: Contributors to GDB -@end menu - -@node Free Software, Contributors, Summary, Summary -@unnumberedsec Free Software -_GDBN__ is @dfn{free software}, protected by the GNU General Public License (GPL). -The GPL gives you the freedom to copy or adapt a licensed -program---but every person getting a copy also gets with it the -freedom to modify that copy (which means that they must get access to -the source code), and the freedom to distribute further copies. -Typical software companies use copyrights to limit your freedoms; the -Free Software Foundation uses the GPL to preserve these freedoms. - -Fundamentally, the General Public License is a license which says that -you have these freedoms and that you can't take these freedoms away -from anyone else. - -@c FIXME: (passim) go through all xrefs, expanding to use text headings -For full details, @pxref{Copying}. -@node Contributors, , Free Software, Summary -@unnumberedsec Contributors to GDB - -Richard Stallman was the original author of GDB, as with many GNU -programs.

As major maintainer of GDB -for some period, each contributed significantly to the structure, -stability, and capabilities of the entire debugger. - -Richard Stallman, assisted at various times by Pete TerMaat, Chris -Hanson, and Richard Mlynarik, handled releases through 2.8. - -Michael Tiemann is the author of most of the GNU C++ support in GDB, -with significant additional contributions from Per Bothner. James -Clark wrote the GNU C++ demangler. Early work on C++ was by Peter -TerMaat (who also did much general update work leading to release 3.0). - -GDB 4.0 uses the BFD subroutine library to examine multiple -object-file formats; BFD was a joint project of V. Gumby -Henkel-Wallace, Rich Pixley, Steve Chamberlain, and John Gilmore. - -David Johnson wrote the original COFF support; Pace Willison did -the original support for encapsulated COFF. - -Adam de Boor and Bradley Davis contributed the ISI Optimum V support. -Per Bothner, Noboyuki Hikichi, and Alessandro Forin contributed MIPS -support. Jean-Daniel Fekete contributed Sun 386i support. Chris -Hanson improved the HP9000 support. Noboyuki Hikichi and Tomoyuki -Hasei contributed Sony/News OS 3 support. David Johnson contributed -Encore Umax support. Jyrki Kuoppala contributed Altos 3068 support. -Keith Packard contributed NS32K support. Doug Rabson contributed -Acorn Risc Machine support. Chris Smith contributed Convex support -(and Fortran debugging). Jonathan Stone contributed Pyramid support. -Michael Tiemann contributed SPARC support. Tim Tucker contributed -support for the Gould NP1 and Gould Powernode. Pace Willison -contributed Intel 386 support. Jay Vosburgh contributed Symmetry -support. - -Rich Schaefer helped with support of SunOS shared libraries. - -Jay Fenlason and Roland McGrath ensured that GDB and GAS agree about -several machine instruction sets. - -Patrick Duval, Ted Goldstein, Vikram Koka and Glenn Engel helped -develop remote debugging.

You can use a -watchpoint to stop execution whenever the value of an expression -changes, without having to predict a particular place in your program -where this may happen. - -@item Object Code Formats -_GDBN__ uses a new scheme called Binary File Descriptors (BFD) to permit -it to switch dynamically, without reconfiguration or recompilation, -between different object-file formats. Formats currently supported are -COFF, a.out, and the Intel 960 b.out; files may be read as .o's, archive -libraries, or core dumps. BFD is available as a subroutine library so -that other programs may take advantage of it, and the other GNU binary -utilities are being converted to use it. - -@item Configuration -Compile-time configuration (to select a particular architecture and -operating system) is much easier. The script @code{config.gdb} now -handles specification of separate host and target configurations. - -@item Interaction -The user interface to _GDBN__'s control variables has been simplified -and consolidated in two commands, @code{set} and @code{show}. Output -lines are now broken at readable places, rather than overflowing onto -the next line. You can suppress output of machine-level addresses, -displaying only source language information. - - -@item Source Language -_GDBN__ now has limited support for C++ exception handling: _GDBN__ can -break when an exception is raised, before the stack is peeled back to -the exception handler's context. - -@item Command Rationalization -Many _GDBN__ commands have been renamed to make them easier to remember -and use. In particular, the subcommands of @code{info} and -@code{show}/@code{set} are grouped to make the former refer to the state -of your program, and the latter refer to the state of _GDBN__ itself. -@xref{Renamed Commands}, for details on what commands were renamed. - -@item Ports -_GDBN__ has been ported to the following new architectures: AT&T 3b1, -Acorn RISC machine, HP300 running HPUX, big- and little-endian MIPS -machines, Motorola 88k, Sun 386i, and Sun 3 running SunOS 4. In -addition, the following are supported as targets only: AMD 29k, Intel -960, and Wind River's VxWorks. - -@item Shared Libraries -_GDBN__ 4.0 supports SunOS shared libraries. - -@item Work in Progress -Kernel debugging for BSD and Mach systems; Tahoe and HPPA architecture -support. - -@end table - diff --git a/gdb/doc/gdbinv-m.m4 b/gdb/doc/gdbinv-m.m4 index 8fe5f91..e69de29 100755 --- a/gdb/doc/gdbinv-m.m4 +++ b/gdb/doc/gdbinv-m.m4 @@ -1,13 +0,0 @@ -_dnl__ -*- Texinfo -*- -_dnl__ Copyright (c) 1991 Free Software Foundation, Inc. -_dnl__ This file is part of the source for the GDB manual. -_dnl__ M4 FRAGMENT: $Id$ -_if__(_I960__) -* i960-Nindy Remote:: _GDBN__ with a Remote i960 (Nindy) -_fi__(_I960__) -_if__(_AMD29K__) -* EB29K Remote:: _GDBN__ with a Remote EB29K -_fi__(_AMD29K__) -_if__(_VXWORKS__) -* VxWorks Remote:: _GDBN__ and VxWorks -_fi__(_VXWORKS__) diff --git a/gdb/doc/gdbinv-s.m4 b/gdb/doc/gdbinv-s.m4 index e0814be..e69de29 100755 --- a/gdb/doc/gdbinv-s.m4 +++ b/gdb/doc/gdbinv-s.m4 @@ -1,427 +0,0 @@ -_dnl__ -*- Texinfo -*- -_dnl__ Copyright (c) 1990 1991 Free Software Foundation, Inc. -_dnl__ This file is part of the source for the GDB manual. -@c M4 FRAGMENT $Id$ -@c This text diverted to "Remote Debugging" section in general case; -@c however, if we're doing a manual specifically for one of these, it -@c belongs up front (in "Getting In and Out" chapter). -_if__(_I960__) -_if__(!_GENERIC__) -@node i960-Nindy Remote, EB29K Remote, Mode Options, Starting _GDBN__ -_fi__(!_GENERIC__) -_if__(_GENERIC__) -@node i960-Nindy Remote, EB29K Remote, Remote, Remote -_fi__(_GENERIC__) -@subsection _GDBN__ with a Remote i960 (Nindy) - -@cindex Nindy -@cindex i960 -@dfn{Nindy} is a ROM Monitor program for Intel 960 target systems.

-_GDBN__ can do four main kinds of things (plus other things in support of -these) to help you catch bugs in the act: - -@itemize @bullet -@item -Start your program, specifying anything that might affect its behavior. - -@item -Make your program stop on specified conditions. - -@item -Examine what has happened, when your program has stopped. - -@item -Change things in your program, so you can experiment with correcting the -effects of one bug and go on to learn about another. -@end itemize -

-Richard Stallman was the original author of GDB, and of many other GNU -programs.

As major maintainer of GDB -for some period, each contributed significantly to the structure, -stability, and capabilities of the entire debugger. - -Richard Stallman, assisted at various times by Pete TerMaat, Chris -Hanson, and Richard Mlynarik, handled releases through 2.8. - -Michael Tiemann is the author of most of the GNU C++ support in GDB, -with significant additional contributions from Per Bothner. James -Clark wrote the GNU C++ demangler. Early work on C++ was by Peter -TerMaat (who also did much general update work leading to release 3.0). - -GDB _GDB_VN__ uses the BFD subroutine library to examine multiple -object-file formats; BFD was a joint project of V. Gumby -Henkel-Wallace, Rich Pixley, Steve Chamberlain, and John Gilmore. - -David Johnson wrote the original COFF support; Pace Willison did -the original support for encapsulated COFF. - -Adam de Boor and Bradley Davis contributed the ISI Optimum V support. -Per Bothner, Noboyuki Hikichi, and Alessandro Forin contributed MIPS -support. Jean-Daniel Fekete contributed Sun 386i support. Chris -Hanson improved the HP9000 support. Noboyuki Hikichi and Tomoyuki -Hasei contributed Sony/News OS 3 support. David Johnson contributed -Encore Umax support. Jyrki Kuoppala contributed Altos 3068 support. -Keith Packard contributed NS32K support. Doug Rabson contributed -Acorn Risc Machine support. Chris Smith contributed Convex support -(and Fortran debugging). Jonathan Stone contributed Pyramid support. -Michael Tiemann contributed SPARC support. Tim Tucker contributed -support for the Gould NP1 and Gould Powernode. Pace Willison -contributed Intel 386 support. Jay Vosburgh contributed Symmetry -support. - -Rich Schaefer and Peter Schauer helped with support of SunOS shared -libraries. - -Jay Fenlason and Roland McGrath ensured that GDB and GAS agree about -several machine instruction sets. - -Patrick Duval, Ted Goldstein, Vikram Koka and Glenn Engel helped -develop remote debugging. Intel Corporation and Wind River Systems -contributed remote debugging modules for their products. - -Brian Fox is the author of the readline libraries providing -command-line editing and command history. - -Andrew Beers of SUNY Buffalo wrote the language-switching code and -the Modula-2 support, and contributed the Languages chapter of this -manual. - -@node New Features, Sample Session, Summary, Top -@unnumbered New Features since _GDBN__ version 3.5 - -@table @emph -@item Targets -Using the new command @code{target}, you can select at runtime whether -you are debugging local files, local processes, standalone systems over -a serial port, realtime systems over a TCP/IP connection, etc. The -command @code{load} can download programs into a remote system. Serial -stubs are available for Motorola 680x0 and Intel 80386 remote systems; -_GDBN__ also supports debugging realtime processes running under -VxWorks, using SunRPC Remote Procedure Calls over TCP/IP to talk to a -debugger stub on the target system. Internally, _GDBN__ now uses a -function vector to mediate access to different targets; if you need to -add your own support for a remote protocol, this makes it much easier. - -@item Watchpoints -_GDBN__ now sports watchpoints as well as breakpoints. You can use a -watchpoint to stop execution whenever the value of an expression -changes, without having to predict a particular place in your program -where this may happen. - -@item Wide Output -Commands that issue wide output now insert newlines at places designed -to make the output more readable. - -@item Object Code Formats -_GDBN__ uses a new library called the Binary File Descriptor (BFD) -Library to permit it to switch dynamically, without reconfiguration or -recompilation, between different object-file formats. Formats currently -supported are COFF, a.out, and the Intel 960 b.out; files may be read as -.o's, archive libraries, or core dumps. BFD is available as a -subroutine library so that other programs may take advantage of it, and -the other GNU binary utilities are being converted to use it. - -@item Configuration and Ports -Compile-time configuration (to select a particular architecture and -operating system) is much easier. The script @code{configure} now -allows you to configure _GDBN__ as either a native debugger or a -cross-debugger. @xref{Installing _GDBN__} for details on how to -configure and on what architectures are now available. - -@item Interaction -The user interface to _GDBN__'s control variables has been simplified -and consolidated in two commands, @code{set} and @code{show}. Output -lines are now broken at readable places, rather than overflowing onto -the next line. You can suppress output of machine-level addresses, -displaying only source language information. - - -@item C++ -_GDBN__ now supports C++ multiple inheritance (if used with a GCC -version 2 compiler), and also has limited support for C++ exception -handling, with the commands @code{catch} and @code{info catch}: _GDBN__ -can break when an exception is raised, before the stack is peeled back -to the exception handler's context. - -@item Modula-2 -_GDBN__ now has preliminary support for the GNU Modula-2 compiler, -currently under development at the State University of New York at -Buffalo. Coordinated development of both _GDBN__ and the GNU Modula-2 -compiler will continue through the fall of 1991 and into 1992. Other -Modula-2 compilers are currently not supported, and attempting to debug -programs compiled with them will likely result in an error as the symbol -table of the executable is read in. - -@item Command Rationalization -Many _GDBN__ commands have been renamed to make them easier to remember -and use. In particular, the subcommands of @code{info} and -@code{show}/@code{set} are grouped to make the former refer to the state -of your program, and the latter refer to the state of _GDBN__ itself. -@xref{Renamed Commands}, for details on what commands were renamed. - -@item Shared Libraries -_GDBN__ _GDB_VN__ can debug programs and core files that use SunOS shared -libraries. - -@item Reference Card -_GDBN__ _GDB_VN__ has a reference card; @xref{Formatting Documentation} for -instructions on printing it. - -@item Work in Progress -Kernel debugging for BSD and Mach systems; Tahoe and HPPA architecture -support. - -@end table - -@node Sample Session, Invocation, New Features, Top -@chapter A Sample _GDBN__ Session - -You can use this manual at your leisure to read all about _GDBN__. -However, a handful of commands are enough to get started using the -debugger. This chapter illustrates these commands. - -@iftex -In this sample session, we emphasize user input like this: @i{input}, -to make it easier to pick out from the surrounding output. -@end iftex - -@c FIXME: this example may not be appropriate for some configs, where -@c FIXME...primary interest is in remote use. -_0__ -One of the preliminary versions of GNU @code{m4} (a generic macro -processor) exhibits the following bug: sometimes, when we change its -quote strings from the default, the commands used to capture one macro's -definition in another stop working. In the following short @code{m4} -session, we define a macro @code{foo} which expands to @code{0000}; we -then use the @code{m4} builtin @code{defn} to define @code{bar} as the -same thing.

In contrast, a @code{next} command at the end -of a loop will simply step back to the beginning of the loop, which -would force you to step through the next iteration. - -@code{until} always stops the program if it attempts to exit the current -stack frame. - -@code{until} may produce somewhat counterintuitive results if the order -of machine code does not match the order of the source lines.

Play it safe and give a specific, complete example. That is the -easiest thing for you to do, and the most helpful. - -Keep in mind that the purpose of a bug report is to enable us to fix -the bug if it is new to us.

However, -you should make sure that the shell on your path (named by the -@samp{SHELL} environment variable) is publicly readable; some systems -refuse to let _GDBN__ debug child processes whose programs are not -readable, and _GDBN__ uses the shell to start your program. - -@menu -* Subdirectories:: Configuration subdirectories -* Config Names:: Specifying names for hosts and targets -* configure Options:: Summary of options for configure -* Formatting Documentation:: How to format and print _GDBN__ documentation -@end menu - - -@node Subdirectories, Config Names, Installing _GDBN__, Installing _GDBN__ -@section Configuration Subdirectories -If you want to run _GDBN__ versions for several host or target machines, -you'll need a different _GDBP__ compiled for each combination of host -and target. @code{configure} is designed to make this easy by allowing -you to generate each configuration in a separate subdirectory. If your -@code{make} program handles the @samp{VPATH} feature (GNU @code{make} -does), running @code{make} in each of these directories then builds the -_GDBP__ program specified there. - -@code{configure} creates these subdirectories for you when you -simultaneously specify several configurations; but it's a good habit -even for a single configuration. You can specify the use of -subdirectories using the @samp{+subdirs} option (abbreviated -@samp{+sub}). For example, you can build _GDBN__ on a Sun 4 as follows: - -@example -@group -cd gdb-_GDB_VN__ -./configure +sub sun4 -cd Host-sparc-sun-sunos4/Target-sparc-sun-sunos4 -make -@end group -@end example - -When @code{configure} uses subdirectories to build programs or -libraries, it creates nested directories -@file{Host-@var{host}/Target-@var{target}}. (As you see in the example, -the names used for @var{host} and @var{target} may be expanded from your -@code{configure} argument; @pxref{Config Names}). @code{configure} uses -these two directory levels because _GDBN__ can be configured for -cross-compiling: _GDBN__ can run on one machine (the host) while -debugging programs that run on another machine (the target). You -specify cross-debugging targets by giving the -@samp{+target=@var{target}} option to @code{configure}. Specifying only -hosts still gives you two levels of subdirectory for each host, with the -same configuration suffix on both; that is, if you give any number of -hosts but no targets, _GDBN__ will be configured for native debugging on -each host. On the other hand, whenever you specify both hosts and -targets on the same command line, @code{configure} creates all -combinations of the hosts and targets you list.@refill - -When you run @code{make} to build a program or library, you must run it -in a configured directory. If you made a single configuration, -without subdirectories, run @code{make} in the source directory. -If you have @file{Host-@var{host}/Target-@var{target}} subdirectories, -run @code{make} in those subdirectories. - -Each @code{configure} and @code{Makefile} under each source directory -runs recursively, so that typing @code{make} in @file{gdb-_GDB_VN__} (or in a -@file{gdb-_GDB_VN__/Host-@var{host}/Target-@var{target}} subdirectory) -builds all the required libraries, then _GDBN__.@refill - -If you run @code{configure} from a directory (such as @file{gdb-_GDB_VN__}) that -contains source directories for multiple libraries or programs, -@code{configure} creates the @file{Host-@var{host}/Target-@var{target}} -subdirectories in each library or program's source directory.

By contrast, the GNU General Public -License is intended to guarantee your freedom to share and change free -software---to make sure the software is free for all its users. This -General Public License applies to most of the Free Software -Foundation's software and to any other program whose authors commit to -using it. (Some other Free Software Foundation software is covered by -the GNU Library General Public License instead.) You can apply it to -your programs, too. - - When we speak of free software, we are referring to freedom, not -price. Our General Public Licenses are designed to make sure that you -have the freedom to distribute copies of free software (and charge for -this service if you wish), that you receive source code or can get it -if you want it, that you can change the software or use pieces of it -in new free programs; and that you know you can do these things. - - To protect your rights, we need to make restrictions that forbid -anyone to deny you these rights or to ask you to surrender the rights. -These restrictions translate to certain responsibilities for you if you -distribute copies of the software, or if you modify it. - - For example, if you distribute copies of such a program, whether -gratis or for a fee, you must give the recipients all the rights that -you have. You must make sure that they, too, receive or can get the -source code. And you must show them these terms so they know their -rights. - - We protect your rights with two steps: (1) copyright the software, and -(2) offer you this license which gives you legal permission to copy, -distribute and/or modify the software. - - Also, for each author's protection and ours, we want to make certain -that everyone understands that there is no warranty for this free -software. If the software is modified by someone else and passed on, we -want its recipients to know that what they have is not the original, so -that any problems introduced by others will not reflect on the original -authors' reputations. - - Finally, any free program is threatened constantly by software -patents. We wish to avoid the danger that redistributors of a free -program will individually obtain patent licenses, in effect making the -program proprietary. To prevent this, we have made it clear that any -patent must be licensed for everyone's free use or not licensed at all. - - The precise terms and conditions for copying, distribution and -modification follow. - -@iftex -@unnumberedsec TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION -@end iftex -@ifinfo -@center TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION -@end ifinfo - -@enumerate -@item -This License applies to any program or other work which contains -a notice placed by the copyright holder saying it may be distributed -under the terms of this General Public License. The ``Program'', below, -refers to any such program or work, and a ``work based on the Program'' -means either the Program or any derivative work under copyright law: -that is to say, a work containing the Program or a portion of it, -either verbatim or with modifications and/or translated into another -language. (Hereinafter, translation is included without limitation in -the term ``modification''.) Each licensee is addressed as ``you''. - -Activities other than copying, distribution and modification are not -covered by this License; they are outside its scope. The act of -running the Program is not restricted, and the output from the Program -is covered only if its contents constitute a work based on the -Program (independent of having been made by running the Program). -Whether that is true depends on what the Program does. - -@item -You may copy and distribute verbatim copies of the Program's -source code as you receive it, in any medium, provided that you -conspicuously and appropriately publish on each copy an appropriate -copyright notice and disclaimer of warranty; keep intact all the -notices that refer to this License and to the absence of any warranty; -and give any other recipients of the Program a copy of this License -along with the Program. - -You may charge a fee for the physical act of transferring a copy, and -you may at your option offer warranty protection in exchange for a fee. - -@item -You may modify your copy or copies of the Program or any portion -of it, thus forming a work based on the Program, and copy and -distribute such modifications or work under the terms of Section 1 -above, provided that you also meet all of these conditions: - -@alphaenumerate -@item -You must cause the modified files to carry prominent notices -stating that you changed the files and the date of any change. - -@item -You must cause any work that you distribute or publish, that in -whole or in part contains or is derived from the Program or any -part thereof, to be licensed as a whole at no charge to all third -parties under the terms of this License. - -@item -If the modified program normally reads commands interactively -when run, you must cause it, when started running for such -interactive use in the most ordinary way, to print or display an -announcement including an appropriate copyright notice and a -notice that there is no warranty (or else, saying that you provide -a warranty) and that users may redistribute the program under -these conditions, and telling the user how to view a copy of this -License. (Exception: if the Program itself is interactive but -does not normally print such an announcement, your work based on -the Program is not required to print an announcement.) -@end alphaenumerate - -These requirements apply to the modified work as a whole. If -identifiable sections of that work are not derived from the Program, -and can be reasonably considered independent and separate works in -themselves, then this License, and its terms, do not apply to those -sections when you distribute them as separate works. But when you -distribute the same sections as part of a whole which is a work based -on the Program, the distribution of the whole must be on the terms of -this License, whose permissions for other licensees extend to the -entire whole, and thus to each and every part regardless of who wrote it. - -Thus, it is not the intent of this section to claim rights or contest -your rights to work written entirely by you; rather, the intent is to -exercise the right to control the distribution of derivative or -collective works based on the Program. - -In addition, mere aggregation of another work not based on the Program -with the Program (or with a work based on the Program) on a volume of -a storage or distribution medium does not bring the other work under -the scope of this License. - -@item -You may copy and distribute the Program (or a work based on it, -under Section 2) in object code or executable form under the terms of -Sections 1 and 2 above provided that you also do one of the following: - -@alphaenumerate -@item -Accompany it with the complete corresponding machine-readable -source code, which must be distributed under the terms of Sections -1 and 2 above on a medium customarily used for software interchange; or, - -@item -Accompany it with a written offer, valid for at least three -years, to give any third party, for a charge no more than your -cost of physically performing source distribution, a complete -machine-readable copy of the corresponding source code, to be -distributed under the terms of Sections 1 and 2 above on a medium -customarily used for software interchange; or, - -@item -Accompany it with the information you received as to the offer -to distribute corresponding source code. (This alternative is -allowed only for noncommercial distribution and only if you -received the program in object code or executable form with such -an offer, in accord with Subsection b above.) -@end alphaenumerate - -The source code for a work means the preferred form of the work for -making modifications to it. For an executable work, complete source -code means all the source code for all modules it contains, plus any -associated interface definition files, plus the scripts used to -control compilation and installation of the executable. However, as a -special exception, the source code distributed need not include -anything that is normally distributed (in either source or binary -form) with the major components (compiler, kernel, and so on) of the -operating system on which the executable runs, unless that component -itself accompanies the executable. - -If distribution of executable or object code is made by offering -access to copy from a designated place, then offering equivalent -access to copy the source code from the same place counts as -distribution of the source code, even though third parties are not -compelled to copy the source along with the object code. - -@item -You may not copy, modify, sublicense, or distribute the Program -except as expressly provided under this License. Any attempt -otherwise to copy, modify, sublicense or distribute the Program is -void, and will automatically terminate your rights under this License. -However, parties who have received copies, or rights, from you under -this License will not have their licenses terminated so long as such -parties remain in full compliance. - -@item -You are not required to accept this License, since you have not -signed it. However, nothing else grants you permission to modify or -distribute the Program or its derivative works. These actions are -prohibited by law if you do not accept this License. Therefore, by -modifying or distributing the Program (or any work based on the -Program), you indicate your acceptance of this License to do so, and -all its terms and conditions for copying, distributing or modifying -the Program or works based on it. - -@item -Each time you redistribute the Program (or any work based on the -Program), the recipient automatically receives a license from the -original licensor to copy, distribute or modify the Program subject to -these terms and conditions.

If you cannot -distribute so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you -may not distribute the Program at all. For example, if a patent -license would not permit royalty-free redistribution of the Program by -all those who receive copies directly or indirectly through you, then -the only way you could satisfy both it and this License would be to -refrain entirely from distribution of the Program. - -If any portion of this section is held invalid or unenforceable under -any particular circumstance, the balance of the section is intended to -apply and the section as a whole is intended to apply in other -circumstances. - -It is not the purpose of this section to induce you to infringe any -patents or other property right claims or to contest validity of any -such claims; this section has the sole purpose of protecting the -integrity of the free software distribution system, which is -implemented by public license practices. Many people have made -generous contributions to the wide range of software distributed -through that system in reliance on consistent application of that -system; it is up to the author/donor to decide if he or she is willing -to distribute software through any other system and a licensee cannot -impose that choice. - -This section is intended to make thoroughly clear what is believed to -be a consequence of the rest of this License. - -@item -If the distribution and/or use of the Program is restricted in -certain countries either by patents or by copyrighted interfaces, the -original copyright holder who places the Program under this License -may add an explicit geographical distribution limitation excluding -those countries, so that distribution is permitted only in or among -countries not thus excluded. In such case, this License incorporates -the limitation as if written in the body of this License. - -@item -The Free Software Foundation may publish revised and/or new versions -of the General Public License from time to time. Such new versions will -be similar in spirit to the present version, but may differ in detail to -address new problems or concerns. - -Each version is given a distinguishing version number. If the Program -specifies a version number of this License which applies to it and ``any -later version'', you have the option of following the terms and conditions -either of that version or of any later version published by the Free -Software Foundation. If the Program does not specify a version number of -this License, you may choose any version ever published by the Free Software -Foundation. - -@item -If you wish to incorporate parts of the Program into other free -programs whose distribution conditions are different, write to the author -to ask for permission. For software which is copyrighted by the Free -Software Foundation, write to the Free Software Foundation; we sometimes -make exceptions for this.

When your code does something (like malloc some memory, or open -a file) that needs to be undone later (e.g. free the memory or close -the file), it can make a cleanup. The cleanup will be done at some -future point: when the command is finished, when an error occurs, or -when your code decides it's time to do cleanups. - -You can also discard cleanups, that is, throw them away without doing -what they say. This is only done if you ask that it be done. - -Syntax: - -@table @code -@item old_chain = make_cleanup (function, arg); -This makes a cleanup which will cause FUNCTION to be called with ARG -(a char *) later. The result, OLD_CHAIN, is a handle that can be -passed to do_cleanups or discard_cleanups later. Unless you are -going to call do_cleanups or discard_cleanups yourself, -you can ignore the result from make_cleanup. - - -@item do_cleanups (old_chain); -Performs all cleanups done since make_cleanup returned OLD_CHAIN. -E.g.: make_cleanup (a, 0); old = make_cleanup (b, 0); do_cleanups (old); -will call b() but will not call a(). The cleanup that calls a() will remain -in the cleanup chain, and will be done later unless otherwise discarded. - -@item discard_cleanups (old_chain); -Same as do_cleanups except that it just removes the cleanups from the -chain and does not call the specified functions. - -@end table - -Some functions, e.g. @code{fputs_filtered()} or @code{error()}, specify that they -``should not be called when cleanups are not in place''. This means -that any actions you need to reverse in the case of an error or -interruption must be on the cleanup chain before you call these functions, -since they might never return to your code (they @samp{longjmp} instead). - - -@node Wrapping, Releases, Cleanups, Top -@chapter Wrapping output lines - -Output that goes through printf_filtered or fputs_filtered or -fputs_demangled needs only to have calls to wrap_here() added -in places that would be good breaking points. The utility routines -will take care of actually wrapping if the line width is exceeded. - -The argument to wrap_here() is an indentation string which is printed -ONLY if the line breaks there. This argument is saved away and used -later. It must remain valid until the next call to wrap_here() or -until a newline has been printed through the *_filtered functions. -Don't pass in a local variable and then return! - -It is usually best to call wrap_here() after printing a comma or space. -If you call it before printing a space, make sure that your indentation -properly accounts for the leading space that will print if the line wraps -there. - -Any function or set of functions that produce filtered output must finish -by printing a newline, to flush the wrap buffer, before switching to -unfiltered ("printf") output.

If these routines work for the @var{ARCH} host, -you can just include the generic file's name (with .o, not .c) in -@code{XDEPFILES}. Otherwise, you will need to write routines that -perform the same functions as the generic file, put them into -@code{@var{ARCH}-xdep.c}, and put @code{@var{ARCH}-xdep.o} into -@code{XDEPFILES}. These generic host support files include: - -@example - coredep.c, coredep.o -@end example - -@table @code -@item fetch_core_registers() -Support for reading registers out of a core file. This routine calls -@code{register_addr(}), see below. - -@item register_addr() -If your @code{xm-@var{ARCH}.h} file defines the macro @code{REGISTER_U_ADDR(reg)} to be the -offset within the @samp{user} struct of a register (represented as a GDB -register number), @file{coredep.c} will define the @code{register_addr()} function -and use the macro in it. If you do not define @code{REGISTER_U_ADDR}, but -you are using the standard @code{fetch_core_registers}, you -will need to define your own version of @code{register_addr}, put it into -your @code{@var{ARCH}-xdep.c} file, and be sure @code{@var{ARCH}-xdep.o} is in the @code{XDEPFILES} list. -If you have your own @code{fetch_core_registers}, you only need to define -@code{register_addr} if your @code{fetch_core_registers} calls it. Many custom -@code{fetch_core_registers} implementations simply locate the registers -themselves. -@end table - -Files needed when the target system is an @var{ARCH} are listed in the file -@file{tconfig/@var{ARCH}}, in the @code{Makefile} macro @samp{TDEPFILES = }@dots{}.

These functions open and examine an exec file, -extract data from one, write data to one, print information about one, -etc. Now that executable files are handled with BFD, every architecture -should be able to use the generic exec.c rather than its own custom code. - -@node Host versus Target, , README, Top -@chapter What is considered ``host-dependent'' versus ``target-dependent''? - -The xconfig/*, xm-*.h and *-xdep.c files are for host support. The -question is, what features or aspects of a debugging or cross-debugging -environment are considered to be ``host'' support. - -Defines and include files needed to build on the host are host support. -Examples are tty support, system defined types, host byte order, host -float format. - -Unix child process support is considered an aspect of the host. Since -when you fork on the host you are still on the host, the various macros -needed for finding the registers in the upage, running ptrace, and such -are all in the host-dependent files. - -This is still somewhat of a grey area; I (John Gilmore) didn't do the -xm- and tm- split for gdb (it was done by Jim Kingdon) so I have had to -figure out the grounds on which it was split, and make my own choices -as I evolve it.

The second parameter is a pointer to the -* instruction mnemonic. Each operand is specified by offset, width, -* and type. The offset is the bit number of the least significant -* bit of the operand with bit 0 being the least significant bit of -* the instruction. The width is the number of bits used to specify -* the operand. The type specifies the output format to be used for -* the operand. The valid formats are: register, register indirect, -* hex constant, and bit field specification. The last field is a -* pointer to the next instruction in the linked list.

The idea -is that you would use these pre-tested macros to solve a -very specific set of problems, and they would run fast. -Caution: no side-effects in arguments please!! They may be -evaluated MANY times!! - -These macros operate a stack of objects. Each object starts life -small, and may grow to maturity. (Consider building a word syllable -by syllable.) An object can move while it is growing. Once it has -been "finished" it never changes address again. So the "top of the -stack" is typically an immature growing object, while the rest of the -stack is of mature, fixed size and fixed address objects. - -These routines grab large chunks of memory, using a function you -supply, called `obstack_chunk_alloc'. On occasion, they free chunks, -by calling `obstack_chunk_free'. You must define them and declare -them before using any obstack macros. - -Each independent stack is represented by a `struct obstack'. -Each of the obstack macros expects a pointer to such a structure -as the first argument. - -One motivation for this package is the problem of growing char strings -in symbol tables. Unless you are "fascist pig with a read-only mind" -[Gosper's immortal quote from HAKMEM item 154, out of context] you -would not like to put any arbitrary upper limit on the length of your -symbols. - -In practice this often means you will build many short symbols and a -few long symbols. At the time you are reading a symbol you don't know -how long it is. One traditional method is to read a symbol into a -buffer, realloc()ating the buffer every time you try to read a symbol -that is longer than the buffer. This is beaut, but you still will -want to copy the symbol from the buffer to a more permanent -symbol-table entry say about half the time. - -With obstacks, you can work differently. Use one obstack for all symbol -names. As you read a symbol, grow the name in the obstack gradually. -When the name is complete, finalize it. Then, if the symbol exists already, -free the newly read name. - -The way we do this is to take a large chunk, allocating memory from -low addresses. When you want to build a symbol in the chunk you just -add chars above the current "high water mark" in the chunk. When you -have finished adding chars, because you got to the end of the symbol, -you know how long the chars are, and you can create a new object. -Mostly the chars will not burst over the highest address of the chunk, -because you would typically expect a chunk to be (say) 100 times as -long as an average object. - -In case that isn't clear, when we have enough chars to make up -the object, THEY ARE ALREADY CONTIGUOUS IN THE CHUNK (guaranteed) -so we just point to it where it lies. No moving of chars is -needed and this is the second win: potentially long strings need -never be explicitly shuffled. Once an object is formed, it does not -change its address during its lifetime. - -When the chars burst over a chunk boundary, we allocate a larger -chunk, and then copy the partly formed object from the end of the old -chunk to the beginning of the new larger chunk.

One, a - * call to set_debug_traps() is necessary in order to allow any breakpoints - * or error conditions to be properly intercepted and reported to gdb. - * Two, a breakpoint needs to be generated to begin communication. This - * is most easily accomplished by a call to breakpoint(). Breakpoint() - * simulates a breakpoint by executing a trap #1. - * - * Some explanation is probably necessary to explain how exceptions are - * handled. When an exception is encountered the 68000 pushes the current - * program counter and status register onto the supervisor stack and then - * transfers execution to a location specified in it's vector table. - * The handlers for the exception vectors are hardwired to jmp to an address - * given by the relation: (exception - 256) * 6. These are decending - * addresses starting from -6, -12, -18, ... By allowing 6 bytes for - * each entry, a jsr, jmp, bsr, ... can be used to enter the exception - * handler. Using a jsr to handle an exception has an added benefit of - * allowing a single handler to service several exceptions and use the - * return address as the key differentiation. The vector number can be - * computed from the return address by [ exception = (addr + 1530) / 6 ]. - * The sole purpose of the routine _catchException is to compute the - * exception number and push it on the stack in place of the return address. - * The external function exceptionHandler() is - * used to attach a specific handler to a specific 68k exception. - * For 68020 machines, the ability to have a return address around just - * so the vector can be determined is not necessary because the '020 pushes an - * extra word onto the stack containing the vector offset - * - * Because gdb will sometimes write to the stack area to execute function - * calls, this program cannot rely on using the supervisor stack so it - * uses it's own stack area reserved in the int array remcomStack. - * - ************* - * - * The following gdb commands are supported: - * - * command function Return value - * - * g return the value of the CPU registers hex data or ENN - * G set the value of the CPU registers OK or ENN - * - * mAA..AA,LLLL Read LLLL bytes at address AA..AA hex data or ENN - * MAA..AA,LLLL: Write LLLL bytes at address AA.AA OK or ENN - * - * c Resume at current address SNN ( signal NN) - * cAA..AA Continue at address AA..AA SNN - * - * s Step one instruction SNN - * sAA..AA Step one instruction from AA..AA SNN - * - * k kill - * - * ? What was the last sigval ? SNN (signal NN) - * - * All commands and responses are sent with a packet which includes a - * checksum. A packet consists of - * - * $<packet info>#<checksum>. - * - * where - * <packet info> :: <characters representing the command or response> - * <checksum> :: < two hex digits computed as modulo 256 sum of <packetinfo>> - * - * When a packet is received, it is first acknowledged with either '+' or '-'. - * '+' indicates a successful transfer.

One, a - * call to set_debug_traps() is necessary in order to allow any breakpoints - * or error conditions to be properly intercepted and reported to gdb. - * Two, a breakpoint needs to be generated to begin communication. This - * is most easily accomplished by a call to breakpoint(). Breakpoint() - * simulates a breakpoint by executing a trap #1. - * - * Some explanation is probably necessary to explain how exceptions are - * handled. When an exception is encountered the 68000 pushes the current - * program counter and status register onto the supervisor stack and then - * transfers execution to a location specified in it's vector table. - * The handlers for the exception vectors are hardwired to jmp to an address - * given by the relation: (exception - 256) * 6. These are decending - * addresses starting from -6, -12, -18, ... By allowing 6 bytes for - * each entry, a jsr, jmp, bsr, ... can be used to enter the exception - * handler. Using a jsr to handle an exception has an added benefit of - * allowing a single handler to service several exceptions and use the - * return address as the key differentiation. The vector number can be - * computed from the return address by [ exception = (addr + 1530) / 6 ]. - * The sole purpose of the routine _catchException is to compute the - * exception number and push it on the stack in place of the return address. - * The external function exceptionHandler() is - * used to attach a specific handler to a specific 68k exception. - * For 68020 machines, the ability to have a return address around just - * so the vector can be determined is not necessary because the '020 pushes an - * extra word onto the stack containing the vector offset - * - * Because gdb will sometimes write to the stack area to execute function - * calls, this program cannot rely on using the supervisor stack so it - * uses it's own stack area reserved in the int array remcomStack. - * - ************* - * - * The following gdb commands are supported: - * - * command function Return value - * - * g return the value of the CPU registers hex data or ENN - * G set the value of the CPU registers OK or ENN - * - * mAA..AA,LLLL Read LLLL bytes at address AA..AA hex data or ENN - * MAA..AA,LLLL: Write LLLL bytes at address AA.AA OK or ENN - * - * c Resume at current address SNN ( signal NN) - * cAA..AA Continue at address AA..AA SNN - * - * s Step one instruction SNN - * sAA..AA Step one instruction from AA..AA SNN - * - * k kill - * - * ? What was the last sigval ? SNN (signal NN) - * - * All commands and responses are sent with a packet which includes a - * checksum. A packet consists of - * - * $<packet info>#<checksum>. - * - * where - * <packet info> :: <characters representing the command or response> - * <checksum> :: < two hex digits computed as modulo 256 sum of <packetinfo>> - * - * When a packet is received, it is first acknowledged with either '+' or '-'. - * '+' indicates a successful transfer. '-' indicates a failed transfer. - * - * Example: - * - * Host: Reply: - * $m0,10#2a +$00010203040506070809101112131415#42 - * - ****************************************************************************/ - -#include <stdio.h> -#include <string.h> -#include <setjmp.h> - -/************************************************************************ - * - * external low-level support routines - */ -typedef void (*ExceptionHook)(int); /* pointer to function with int parm */ -typedef void (*Function)(); /* pointer to a function */ - -extern putDebugChar(); /* write a single character */ -extern getDebugChar(); /* read and return a single char */ - -extern Function exceptionHandler(); /* assign an exception handler */ -extern ExceptionHook exceptionHook; /* hook variable for errors/exceptions */ - - -/************************************************************************/ -/* BUFMAX defines the maximum number of characters in inbound/outbound buffers*/ -/* at least NUMREGBYTES*2 are needed for register packets */ -#define BUFMAX 400 - -static char initialized; /* boolean flag. != 0 means we've been initialized */ - -int remote_debug = 0; -/* debug > 0 prints ill-formed commands in valid packets & checksum errors */ - -char hexchars[]="0123456789abcdef"; - -/* there are 180 bytes of registers on a 68020 w/68881 */ -/* many of the fpa registers are 12 byte (96 bit) registers */ -#define NUMREGBYTES 180 -enum regnames {D0,D1,D2,D3,D4,D5,D6,D7, - A0,A1,A2,A3,A4,A5,A6,A7, - PS,PC, - FP0,FP1,FP2,FP3,FP4,FP5,FP6,FP7, - FPCONTROL,FPSTATUS,FPIADDR - }; - -typedef struct FrameStruct -{ - struct FrameStruct *previous; - int exceptionPC; /* pc value when this frame created */ - int exceptionVector; /* cpu vector causing exception */ - short frameSize; /* size of cpu frame in words */ - short sr; /* for 68000, this not always sr */ - int pc; - short format; - int fsaveHeader; - int morejunk[0]; /* exception frame, fp save... */ -} Frame; - -#define FRAMESIZE 500 -static Frame *lastFrame; -static int frameStack[FRAMESIZE]; - -/* - * these should not be static cuz they can be used outside this module - */ -int registers[NUMREGBYTES/4]; -int superStack; - -static int remcomStack[400]; -static int* stackPtr = &remcomStack[399]; - -/* - * In many cases, the system will want to continue exception processing - * when a continue command is given. - * oldExceptionHook is a function to invoke in this case. - */ - -static ExceptionHook oldExceptionHook; - -/* the size of the exception stack on the 68020 varies with the type of - * exception.
