Stallman + Everyone is permitted to copy and distribute verbatim copies + of this license, but changing it is not allowed. You can also + use this wording to make the terms for other programs. + + The license agreements of most software companies keep you at the +mercy of those companies. By contrast, our general public license is +intended to give everyone the right to share GDB. To make sure that +you get the rights we want you to have, we need to make restrictions +that forbid anyone to deny you these rights or to ask you to surrender +the rights. Hence this license agreement. + + Specifically, we want to make sure that you have the right to give +away copies of GDB, that you receive source code or else can get it +if you want it, that you can change GDB or use pieces of it in new +free programs, and that you know you can do these things. + + To make sure that everyone has such rights, we have to forbid you to +deprive anyone else of these rights. For example, if you distribute +copies of GDB, 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 tell them their rights. + + Also, for our own protection, we must make certain that everyone +finds out that there is no warranty for GDB. If GDB is modified by +someone else and passed on, we want its recipients to know that what +they have is not what we distributed, so that any problems introduced +by others will not reflect on our reputation. + + Therefore we (Richard Stallman and the Free Software Foundation, +Inc.) make the following terms which say what you must do to be +allowed to distribute or change GDB. + + + COPYING POLICIES + + 1. You may copy and distribute verbatim copies of GDB source code as +you receive it, in any medium, provided that you conspicuously and +appropriately publish on each copy a valid copyright notice "Copyright +(C) 1988 Free Software Foundation, Inc." (or with whatever year is +appropriate); keep intact the notices on all files that refer to this +License Agreement and to the absence of any warranty; and give any +other recipients of the GDB program a copy of this License Agreement +along with the program. You may charge a distribution fee for the +physical act of transferring a copy. + + 2. You may modify your copy or copies of GDB or any portion of it, +and copy and distribute such modifications under the terms of +Paragraph 1 above, provided that you also do the following: + + a) cause the modified files to carry prominent notices stating + that you changed the files and the date of any change; and + + b) cause the whole of any work that you distribute or publish, + that in whole or in part contains or is a derivative of GDB or any + part thereof, to be licensed at no charge to all third parties on + terms identical to those contained in this License Agreement + (except that you may choose to grant more extensive warranty + protection to third parties, at your option). + + c) if the modified program serves as a debugger, cause it when + started running in the simplest and usual way, to print an + announcement including a valid copyright notice "Copyright (C) + 1988 Free Software Foundation, Inc." (or with the year that is + appropriate), saying 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 Agreement. + + d) You may charge a distribution fee for the physical act of + transferring a copy, and you may at your option offer warranty + protection in exchange for a fee. + +Mere aggregation of another unrelated program with this program (or its +derivative) on a volume of a storage or distribution medium does not bring +the other program under the scope of these terms. + + 3. You may copy and distribute GDB (or a portion or derivative of it, +under Paragraph 2) in object code or executable form under the terms of +Paragraphs 1 and 2 above provided that you also do one of the following: + + a) accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of + Paragraphs 1 and 2 above; or, + + b) accompany it with a written offer, valid for at least three + years, to give any third party free (except for a nominal + shipping charge) a complete machine-readable copy of the + corresponding source code, to be distributed under the terms of + Paragraphs 1 and 2 above; or, + + c) accompany it with the information you received as to where the + corresponding source code may be obtained. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form alone.) + +For an executable file, complete source code means all the source code for +all modules it contains; but, as a special exception, it need not include +source code for modules which are standard libraries that accompany the +operating system on which the executable file runs. + + 4. You may not copy, sublicense, distribute or transfer GDB +except as expressly provided under this License Agreement. Any attempt +otherwise to copy, sublicense, distribute or transfer GDB is void and +your rights to use the program under this License agreement shall be +automatically terminated. However, parties who have received computer +software programs from you with this License Agreement will not have +their licenses terminated so long as such parties remain in full compliance. + + 5. If you wish to incorporate parts of GDB into other free programs +whose distribution conditions are different, write to the Free +Software Foundation at 675 Mass Ave, Cambridge, MA 02139. We have not +yet worked out a simple rule that can be stated here, but we will +often permit this. We will be guided by the two goals of preserving +the free status of all derivatives of our free software and of +promoting the sharing and reuse of software. + +In other words, go ahead and share GDB, but don't try to stop +anyone else from sharing it farther. Help stamp out software hoarding! + + NO WARRANTY + + BECAUSE GDB IS LICENSED FREE OF CHARGE, WE PROVIDE ABSOLUTELY NO +WARRANTY, TO THE EXTENT PERMITTED BY APPLICABLE STATE LAW. EXCEPT +WHEN OTHERWISE STATED IN WRITING, FREE SOFTWARE FOUNDATION, INC, +RICHARD M. STALLMAN AND/OR OTHER PARTIES PROVIDE GDB "AS IS" WITHOUT +WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT +LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR +A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND +PERFORMANCE OF GDB IS WITH YOU. SHOULD GDB PROVE DEFECTIVE, YOU +ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW WILL RICHARD M. +STALLMAN, THE FREE SOFTWARE FOUNDATION, INC., AND/OR ANY OTHER PARTY +WHO MAY MODIFY AND REDISTRIBUTE GDB AS PERMITTED ABOVE, BE LIABLE TO +YOU FOR DAMAGES, INCLUDING ANY LOST PROFITS, LOST MONIES, OR OTHER +SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR +INABILITY TO USE (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA +BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY THIRD PARTIES OR A +FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS) GDB, EVEN +IF YOU HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, OR FOR +ANY CLAIM BY ANY OTHER PARTY. diff --git a/gdb/ChangeLog b/gdb/ChangeLog new file mode 100644 index 0000000..7099697 --- /dev/null +++ b/gdb/ChangeLog @@ -0,0 +1,1609 @@ +Sat Sep 3 12:05:36 1988 Richard Stallman (rms at sugar-bombs.ai.mit.edu) + + * Version 2.8 released. + + * valprint.c: include param.h. + + * inflow.c (store_inferior_registers): Fix typo and missing decl. + +Thu Sep 1 13:18:22 1988 Richard Stallman (rms at sugar-bombs.ai.mit.edu) + + * Version 2.7 released. + + * m-hp9k320bsd.h: New file supports BSD on hp9000 series 300. + +Tue Aug 30 17:54:50 1988 Richard Stallman (rms at sugar-bombs.ai.mit.edu) + + * m-news.h ({EXTRACT,STORE}_RETURN_VALUE): Handle floating pt values. + + * inflow.c (store_inferior_registers) [usual case]: + Handle registers longer than one word. + +Sat Aug 27 00:19:32 1988 Richard Stallman (rms at spiff) + + * inflow.c (create_inferior): Use execve to avoid NEWSOS bug in execle. + +Wed Aug 10 20:36:36 1988 Richard Stallman (rms at sugar-bombs.ai.mit.edu) + + * m-news.h: Define READ_DBX_FORMAT, {EXTRACT,STORE}_RETURN_VALUE. + (INVALID_FLOAT): Add 2nd argument. + (vprintf): Define to call _doprnt. + +Tue Jul 26 03:05:28 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu) + + * symmisc.c: (print_symtabs) Check the status of the fopen and + call perror_with_name if needed. + +Sat Jul 23 00:14:20 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu) + + * printcmd.c: (delete_display) Check for existence of display + chain before deleting anything. + +Thu Jul 7 08:47:03 1988 Richard Stallman (rms at sugar-bombs.ai.mit.edu) + + * main.c: New vars win_argv, win_argc, win_prgm to talk to xgdb. + +Thu Jul 7 02:05:29 1988 Pete TerMaat (pete at frosted-flakes.ai.mit.edu) + + * dbxread.c: (define_symbol) store static functions ('f') in the + same way as global functions ('F') -- that is, as `function of + type X' rather than as `X'. + +Mon Jul 4 17:07:31 1988 Pete TerMaat (pete at frosted-flakes.ai.mit.edu) + + * dbxread.c: (read_dbx_symtab) Avoid reading symbol tables of + libraries by checking for symbols which begin with "-l" (in + addition to those which end with ".o"). + +Mon Jun 27 23:27:51 1988 Pete TerMaat (pete at frosted-flakes.ai.mit.edu) + + * dbxread.c: (define_symbol) and coffread.c: (process_coff_symbol) + If the current symbol is a function, assign its type to be + `function of type X' rather than `X'.

Writing a register works through + `store_inferior_registers' which writes one or all registers + from `registers' back to the inferior. + + A register now can have a "raw" data format and a "virtual" + data format, which may require conversion or even be different sizes. + The conversion can be different for different registers. + For example, the 68000 cpu registers need no conversion + and both raw and virtual size is 4, but the 68881 floating point + registers have raw size 12 (for extended fmt) and virtual size 8 + (for double). Macros in the m- file such as REGISTER_BYTES, + REGISTER_BYTE, REGISTER_{RAW,VIRTUAL}_SIZE, and + REGISTER_CONVERT_TO_{RAW,VIRTUAL} control these things. + + `read_register' and `write_register' are usable only on registers + which hold an int and need no conversion (raw fmt = virtual fmt). + For other registers, `read_register_bytes' is used, or + `read_relative_register_raw_bytes'. + + * m-sun3.h: Define the 68881 fp registers. + Know how to recognize insns that save them. + Make dummy frames save them. + + * core.c (read_register, write_registers): Functions deleted. + * findvar.c (read_register, write_registers): New functions, + not the same as the old ones of the same name. + + * findvar.c (supply_register): Function used by + fetch_inferior_registers, etc., to install the register + values fetched from the inferior. + + * findvar.c (read_register_bytes, write_register_bytes): + Read spec'd number of bytes from the byte-array `registers'. + + * findvar.c (read_relative_register_raw_bytes): + Replaces old function `read_relative_register'; accepts + address of where to store the contents; # bytes stored is size + of the specified register in raw format. + + * findvar.c (value_of_register, read_var_value): + Convert register values and values of register variables + from raw format to virtual format. + + * findvar.c (locate_var_value): Like `read_var_value' but + returns value for variable's address. + + * value.h: Add new field VALUE_REGNO to each value.

source-level debugger intended for GNU, +presently running under un*x. + +Before compiling GDB, you must set up links to four files according to +the kind of machine you are running on. To do this, type `config.gdb +machine', where machine is something like `vax' or `sun2'. This +creates links named `param.h', `m-init.h', `opcode.h', and `pinsn.c'. +(Note: we lack information on certain machines.) + +Also, `Makefile' must be changed to say `OBSTACK = obstack.o' instead +of `OBSTACK=-lobstack' (unless you want to install obstack.o as +/lib/libobstack.a). + +Once these files are set up, just `make' will do everything, +producing an executable `gdb' in this directory. + +About the machine-dependent files... + +m-<machine>.h + +This file contains macro definitions that express information +about the machine's registers, stack frame format and instructions. + +m-<machine>init.h + +This file defines one macro, which says how to round up from the +address of the end of the text of one .o file to the beginning of +the text of the next .o file. + +<machine>-opcode.h, <machine>-pinsn.c +These files contain the information necessary to print instructions +for your cpu type. diff --git a/gdb/TAGS b/gdb/TAGS new file mode 100644 index

This could be used if you wish -to debug a core dump instead. GDB+ ignores any core dump file if it is -actually running the program, so the @samp{kill} command is the only -sure way to go back to using the core dump file. - -@item info files -@kindex info files -Print the names of the executable and core dump files currently in -use by GDB+, and the file from which symbols were loaded. -@end table - -While all three file-specifying commands allow both absolute and relative -file names as arguments, GDB+ always converts the file name to an absolute -one and remembers it that way. - -The @samp{symbol-file} command causes GDB+ to forget the contents of its -convenience variables, the value history, and all breakpoints and -auto-display expressions.

This is called the @dfn{initial} frame or the -@dfn{outermost} frame. Each time a function is called, a new frame is -made. Each time a function returns, the frame for that function invocation -is eliminated. If a function is recursive, there can be many frames for -the same function.

This is the most -recently created of all the stack frames that still exist. - -@cindex frame pointer -Inside your program, stack frames are identified by their addresses. A -stack frame consists of many bytes, each of which has its own address; each -kind of computer has a convention for choosing one of those bytes whose -address serves as the address of the frame. Usually this address is kept -in a register called the @dfn{frame pointer register} while execution is -going on in that frame. - -@cindex frame number -GDB+ assigns numbers to all existing stack frames, starting with zero for -the innermost frame, one for the frame that called it, and so on upward. -These numbers do not really exist in your program; they are to give you a -way of talking about stack frames in GDB+ commands. - -@cindex selected frame -Many GDB+ commands refer implicitly to one stack frame. GDB+ records a stack -frame that is called the @dfn{selected} stack frame; you can select any -frame using one set of GDB+ commands, and then other commands will operate -on that frame. When your program stops, GDB+ automatically selects the -innermost frame. - -@node Backtrace, Selection, Frames, Stack -@section Backtraces - -A backtrace is a summary of how the program got where it is.

These things -can be done with @dfn{output formats}. - -The simplest use of output formats is to say how to print a value -already computed. This is done by starting the arguments of the -@samp{print} command with a slash and a format letter. The format -letters supported are: - -@table @samp -@item x -Regard the bits of the value as an integer, and print the integer in -hexadecimal. - -@item d -Print as integer in signed decimal. - -@item u -Print as integer in unsigned decimal. - -@item o -Print as integer in octal. - -@item a -Print as an address, both absolute in hex and then relative -to a symbol defined as an address below it. - -@item c -Regard as an integer and print it as a character constant. - -@item f -Regard the bits of the value as a floating point number and print -using typical floating point syntax. -@end table - -For example, to print the program counter in hex (@pxref{Registers}), type - -@example -p/x $pc -@end example - -@noindent -Note that no space is required before the slash; this is because command -names in GDB+ cannot contain a slash. - -To reprint the last value in the value history with a different format, -you can use the @samp{print} command with just a format and no -expression.

But more generally the term `word' has always -referred to the size of quantity that a machine normally operates on and -stores in its registers. This is 32 bits for all the machines that GNU -runs on. - -@item g -Examine giant words (8 bytes). -@end table - -These letters specify just the way to print the contents: - -@table @samp -@item x -Print as integers in unsigned hexadecimal. - -@item d -Print as integers in signed decimal. - -@item u -Print as integers in unsigned decimal. - -@item o -Print as integers in unsigned octal. - -@item a -Print as an address, both absolute in hex and then relative -to a symbol defined as an address below it. - -@item c -Print as character constants. - -@item f -Print as floating point.

If you don't want -to use any letters after the slash, you can omit the slash as well. - -You can also omit the address to examine. Then the address used is -just after the last unit examined. This is why string and instruction -formats actually compute a unit-size based on the data: so that the -next string or instruction examined will start in the right place. -The @samp{print} command sometimes sets the default address for -the @samp{x} command; when the value printed resides in memory, the -default is set to examine the same location. @samp{info line} also -sets the default for @samp{x}, to the address of the start of the -machine code for the specified line and @samp{info breakpoints} sets -it to the address of the last breakpoint listed. - -When you use @key{RET} to repeat an @samp{x} command, it does not repeat -exactly the same: the address specified previously (if any) is ignored, so -that the repeated command examines the successive locations in memory -rather than the same ones. - -You can examine several consecutive units of memory with one command by -writing a repeat-count after the slash (before the format letters, if any). -The repeat count must be a decimal integer.

For example: - -@example -set $i = 0 -print bar[$i++]->contents -@i{@dots{}repeat that command by typing @key{RET}.} -@end example - -Some convenience variables are created automatically by GDB+ and given -values likely to be useful. - -@table @samp -@item $_ -The variable @samp{$_} is automatically set by the @samp{x} command to -the last address examined (@pxref{Memory}). Other commands which -provide a default address for @samp{x} to examine also set @samp{$_} -to that address; these commands include @samp{info line} and @samp{info -breakpoint}. - -@item $__ -The variable @samp{$__} is automatically set by the @samp{x} command -to the value found in the last address examined. -@end table - -@node Registers,, Convenience Vars, Data -@section Registers - -@cindex registers -Machine register contents can be referred to in expressions as variables -with names starting with @samp{$}. The names of registers are different -for each machine; use @samp{info registers} to see the names used on your -machine. The names @samp{$pc} and @samp{$sp} are used on all machines for -the program counter register and the stack pointer. Often @samp{$fp} is -used for a register that contains a pointer to the current stack frame. - -GDB+ always considers the contents of an ordinary register as an integer -when the register is examined in this way. Programs can store floating -point values in registers also, but there is currently no GDB+ command -to examine a specified register in floating point. (However, if the -variable in your program which is stored in the register is a floating -point variable, you can see the floating point value by examining -the variable.) - -Some machines have special floating point registers. GDB+ considers these -registers' values as floating point when you examine them explicitly. - -Some registers have distinct ``raw'' and ``virtual'' data formats. This -means that the data format in which the register contents are saved by the -operating system is not the same one that your program normally sees. For -example, the registers of the 68881 floating point coprocessor are always -saved in ``extended'' format, but all C programs expect to work with -``double'' format. In such cases, GDB+ normally works with the virtual -format only (the format that makes sense for your program), but the -@samp{info registers} command prints the data in both formats. - -Register values are relative to the selected stack frame -(@pxref{Selection}). This means that you get the value that the register -would contain if all stack frames farther in were exited and their saved -registers restored. In order to see the real contents of all registers, -you must select the innermost frame (with @samp{frame 0}). - -Some registers are never saved (typically those numbered zero or one) -because they are used for returning function values; for these registers, -relativization makes no difference. - -@table @code -@item info registers -@kindex info registers -Print the names and relativized values of all registers. - -@item info registers @var{regname} -Print the relativized value of register @var{regname}. @var{regname} -may be any register name valid on the machine you are using, with -or without the initial @samp{$}. -@end table - -@subsection Examples - -You could print the program counter in hex with - -@example -p/x $pc -@end example - -@noindent -or print the instruction to be executed next with - -@example -x/i $pc -@end example - -@noindent -or add four to the stack pointer with - -@example -set $sp += 4 -@end example - -@noindent -The last is a way of removing one word from the stack, on machines where -stacks grow downward in memory (most machines, nowadays). This assumes -that the innermost stack frame is selected. Setting @samp{$sp} is -not allowed when other stack frames are selected. - -@node Symbols, Altering, Data, Top -@chapter Examining the Symbol Table - -The commands described in this section allow you to make inquiries for -information about the symbols (names of variables, functions and types) -defined in your program. This information is found by GDB+ in the symbol -table loaded by the @samp{symbol-file} command; it is inherent in the text -of your program and does not change as the program executes. - -@table @code -@item whatis @var{exp} -@kindex whatis -Print the data type of expression @var{exp}. @var{exp} is not -actually evaluated, and any side-effecting operations (such as -assignments or function calls) inside it do not take place. - -@item whatis -Print the data type of @samp{$}, the last value in the value history. - -@item info address @var{symbol} -@kindex info address -Describe where the data for @var{symbol} is stored. For register -variables, this says which register. For other automatic variables, -this prints the stack-frame offset at which the variable is always -stored.

GDB+ reads the init file (if any) in your home -directory and then the init file (if any) in the current working -directory. (The init files are not executed if the @samp{-nx} option -is given.)

It can also be used to debug o/s +kernels, but needs to be configured differently for that task. +.PP +Project GNU isn't using Unix man pages. Its style of complete +documentation can be found by: +.PP +The help and info commands inside \fIgdb\fP. +.PP +In the Info system in \fIGNU Emacs\fP. Type C-h i, and follow the +directions. This is equivalent to the reference manual for +\fIgdb\fP, and has about 55 pages of text. +.PP +\fIgdb\fP could be extended to work with other languages (e.g. Pascal) and +machines (e.g. encores). If you like, copy the sources and give it a +try.

This is + why all function calls are in the conditional part. + (gdb reference manual section 5.5). + + 2) A 'return' in a command list also aborts the execution, and + in addition, prompts you for a y/n. + (gdb reference manual section 11.1). + + On the other hand, after doing 'cc -c foo.c' (which is pretty fast), + you can simply rerun your program to check out the changes. + This can be a big win! + +The code for this is included below (compile with cc -g): +======================================================== + +#include <stdio.h> +#include <a.out.h> + +typedef int (*intfun)(); +char *myname; + +intfun funload (filename) /* Dynamically load 1st function from a .o */ + char *filename; +{ + int fd, size; + struct exec hdr; + char buf[100]; + intfun fun; + + /* -A => incremental loading - use dyn as the base symbol table + -T => set the text segment origin to the following hex address + -N => magic number 407 (text not read-only) + */ + sprintf (buf, "ld -A %s -T %x -N %s.o -o %s -lc", + myname, sbrk (0), filename, filename); + + /* NOTE: if anything mallocs space between here and below, this will fail */ + system (buf); + + fd = open (filename, 0); + read (fd, &hdr, sizeof(hdr)); + size = hdr.a_text + hdr.a_data + hdr.a_bss; + + if ((fun = (intfun) sbrk (size)) < 0) + printf ("Couldn't find the space"), exit(); + + read (fd, fun, size); /* Load code. */ + /* NOTE: if anything mallocs space between here and above, this will fail */ + + close (fd); + return ((intfun) fun); +} + +main (argc, argv) + char **argv; +{ + intfun fun1, fun2; + + myname = *argv; + + fun1 = funload("fun1"); + printf ("The answer is %d.\n", (*fun1)(11) ); + + fun2 = funload("fun2"); + printf ("The answer is %d.\n", (*fun2)() ); +} +1,edited,, +Received: by PREP.AI.MIT.EDU; Tue, 16 Jun 87 03:12:54 EDT +Date: Tue, 16 Jun 87 03:12:54 EDT +From: rms (Richard M.

I like it. I think it is lacking in functionality +in the following areas: + +1. "Finish this loop" capability. If I am stepping through code and +encounter a for-, do-, or while-loop, after a few iterations I generally +get bored. I want to be able to say "finish this loop"; i.e. continue +until the next statement after the loop is executed. Note this is +complicated by gotos and nested loops. + +2. GDB only prints the last line of a multi-line statement which has been +continued. Since this is often of the form + + foobar)); + +it is not very convenient. When stepping through a file using next (or step), +ALL non-blank text lines (excepting perhaps close-braces?) between the last +displayed line and the current one should be displayed. + +3. If there is a way to call a function interactively, I couldn't find it +in the on-line help. (Having neither GNU Emacs or TeX, reading the .texinfo +files is a bit tedious.) + +4. On occasion, when debugging a function with deeply nested code in a loop, +I want to have "hierarchical" breakpoints -- that is, I want certain +breakpoints automatically enabled if a certain breakpoint is triggered, +but not if it hasn't. I haven't thought of a good design for this yet. + +5. tbreak is not temporary enough; It should delete the breakpoint, not +disable it. + +6. what about "next to linenumber", or "continue to linenumber" -- the +only difference being next single-steps and continue sets an ephemeral +breakpoint and then deletes it. This would also make debugging large +functions easier. + +7. variable access breakpoints (break when variable changes value) + +8. should be able to use "set" to change initialization values before +"run" is issued. Makes setting of static debugging control variables +easier. Right now I have to break main all the time. + +9. GDB seems to be slow in reading/processing the symbol table -- can +this be improved? + +10. Preprocessor support.
