Also changed "squeakyclean" target as + "realclean". + + * findvar.c (value_from_register): Added assignment of VALUE_LVAL + to be lval_memory when that is appropriate (original code didn't + bother because it assumed that it was working with a pre lval + memoried value). + + * expread.y (yylex): Changed to only return type THIS if the + symbol "$this" is defined in some block superior or equal to the + current expression context block. + +Mon Jan 16 13:56:44 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu) + + * m-*.h (FRAME_CHAIN_VALID): On machines which check the relation + of FRAME_SAVED_PC (thisframe) to first_object_file_end (all except + gould), make sure that the pc of the current frame also passes (in + case someone stops in _start). + + * findvar.c (value_of_register): Changed error message in case of + no inferior or core file. + + * infcmd.c (registers_info): Added a check for inferior or core + file; error message if not. + + * main.c (gdb_read_line): Modified to take prompt as argument and + output it to stdout. + * infcmd.c (registers_info, signals_info), main.c (command_loop, + read_command_lines, copying_info), symtab.c (decode_line_2, + output_source_filename, MORE, list_symbols): Changed calling + convention used to call gdb_read_line. + + * infcmd.c, infrun.c, main.c, symtab.c: Changed the name of the + function "read_line" to "gdb_read_line". + * breakpoint.c: Deleted external referenced to function + "read_line" (not needed by code). + +Fri Jan 13 12:22:05 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu) + + * i386-dep.c: Include a.out.encap.h if COFF_ENCAPSULATE. + (N_SET_MAGIC): Defined if not defined by include file. + (core_file_command): Used N_SET_MAGIC instead of assignment to + a_magic. + (exec_file_command): Stuck in a HEADER_SEEK_FD. + + * config.gdb: Added i386-dep.c as depfile for i386gas choice. + + * munch: Added -I. to cc to pick up things included by the param + file. + + * stab.gnu.def: Changed name to stab.def (stab.gnu.h needs this name). + * Makefile: Changed name here also. + * dbxread.c: Changed name of gnu-stab.h to stab.gnu.h. + + * gnu-stab.h: Changed name to stab.gnu.h. + * stab.gnu.def: Added as link to binutils. + * Makefile: Put both in in the distribution. + +Thu Jan 12 11:33:49 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu) + + * dbxread.c: Made which stab.h is included dependent on + COFF_ENCAPSULATE; either <stab.h> or "gnu-stab.h". + * Makefile: Included gnu-stab.h in the list of files to include in + the distribution. + * gnu-stab.h: Made a link to /gp/gnu/binutils/stab.h + + * Makefile: Included a.out.gnu.h and m-i386gas.h in list of + distribution files. + * m-i386gas.h: Changed to include m-i386.h and fiddle with it + instead of being a whole new file. + * a.out.gnu.h: Made a link to /gp/gnu/binutils/a.out.gnu.h. + + Chris Hanson's changes to gdb for hp Unix. + * Makefile: Modified comments on hpux. + * hp9k320-dep.c: #define'd WOPR & moved inclusion of signal.h + * inflow.c: Moved around declaratiosn of <sys/fcntl.h> and + <sys/ioctl.h> inside of USG depends and deleted all SYSV ifdef's + (use USG instead). + * munch: Modified to accept any number of spaces between the T and + the symbol name. + + Pace's changes to gdb to work with COFF_ENCAPSULATE (robotussin): + * config.gdb: Added i386gas to targets. + * default-dep.c: Include a.out.encap.h if COFF_ENCAPSULATE. + (N_SET_MAGIC): Defined if not defined by include file. + (core_file_command): Used N_SET_MAGIC instead of assignment to a_magic. + (exec_file_command): Stuck in a HEADER_SEEK_FD. + * infrun.c, remote.c: Added an include of a.out.encap.h if + COFF_ENCAPSULATE defined.

This means that all of these *won't* show up in misc + functions (this will be fixed once I make sure it's broken the way + it's supposed to be). - * breakpoint.c (do_breakpoint_commands): - Advance breakpoint_commands before executing the command, - in case command is `cont' and it hits another bpt with commands. + * dbxread.c: Modified placement of debugger globals onto the hash + list; now we exclude the stuff after the colon and don't skip the + first character (debugger symbols don't have underscores). -Sun May 24 20:45:04 1987 Richard M. Stallman (rms at prep) + * dbxread.c: Killed debuginfo stuff with ifdef's. - * value.h: Declare `contents' long and cast its address to char *. +Wed Sep 28 14:31:51 1988 Randall Smith (randy at cream-of-wheat.ai.mit.edu) - * expread.y (prefixify_expression): Don't call alloca among the decls. + * symtab.h, dbxread.c: Modified to deal with BINCL, EINCL, and + EXCL symbols produced by the sun loader by adding a list of + pre-requisite partial_symtabs that each partial symtab needs. - * printcmd.c (print_variable_value): Flush unused local `space'. + * symtab.h, dbxread.c, symtab.c, symmisc.c: Modified to avoid + doing a qsort on the local (static) psymbols for each file to + speed startup. This feature is not completely debugged, but it's + inclusion has forced the inclusion of another feature (dealing + with EINCL's, BINCL's and EXCL's) and so I'm going to go in and + deal with them. - * main.c (execute_command): Barf on "user" like other class names. + * dbxread.c (process_symbol_for_psymtab): Made sure that the class + of the symbol made it into the partial_symbol entry. -Fri May 22 01:34:37 1987 Richard M. Stallman (rms at prep) +Tue Sep 27 15:10:26 1988 Randall Smith (randy at gluteus.ai.mit.edu) - * m68k-pinsn.c (fetch_arg): New arg position 'j', for movec. - (print_insn_arg): New arg syntax 'J', for movec. - * m68k-opcode.h: movec uses 'Jj'.

Changed + help_cmd_list to recognize this flag and modified unset, + undisplay, and enable, disable, and delete breakpoints to have + this flag set. - * dbxread.c (read_enum_type): Don't allocate the type here; - take it as an argument. (Like read_struct_type.) - (read_type)): Before call to read_enum_type, allocate the type - or get the one already allocated. +Wed Sep 21 13:34:19 1988 Randall Smith (randy at plantaris.ai.mit.edu) - * printcmd.c (print_frame_args): Print a comma before - every arg except the first. + * breakpoint.c, infcmd.c, gdb.texinfo: Created "unset" as an alias + for delete, and changed "unset-environment" to be the + "environment" subcommand of "delete". -Wed May 13 00:36:00 1987 Richard M. Stallman (rms at prep) + * gdb.texinfo, valprint.c: Added documentation in the manual for + breaking the set-* commands into subcommands of set.

Used in + value_at to detect references to addresses which are out of + bounds. Also core.c (xfer_core_file): return 1 if invalid + address, 0 otherwise. - * source.c (directory_command): - If dir is already in source_path, don't append another copy of it. + * inflow.c, <machine>-infdep.c: removed all calls to ptrace from + inflow.c and put them in machine-dependent files *-infdep.c. -Thu Jan 22 00:31:03 1987 Richard M.

Their contents are kept in - `registers', an array of bytes. This is done by - `fetch_inferior_registers'. `read_register', etc., just look - there. Writing a register works through - `store_inferior_registers' which writes one or all registers - from `registers' back to the inferior. + * C++: valops.c, valprint.c, value.h, values.c: merged code to deal + with C++ expressions. - 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. +Wed Jul 6 03:28:18 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu) - `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'. + * C++: dbxread.c: (read_dbx_symtab, condense_misc_bunches, + add_file_command) Merged code to read symbol information from + an incrementally linked file. symmisc.c: + (init_free_inclink_symtabs, free_inclink_symtabs) Cleanup + routines. - * m-sun3.h: Define the 68881 fp registers. - Know how to recognize insns that save them. - Make dummy frames save them. +Tue Jul 5 02:50:41 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu) - * 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. + * C++: symtab.c, breakpoint.c, source.c: Merged code to deal with + ambiguous line specifications. In C++ one can have overloaded + function names, so that `list classname::overloadedfuncname' + refers to several different lines, possibly in different files. - * findvar.c (supply_register): Function used by - fetch_inferior_registers, etc., to install the register - values fetched from the inferior. +Fri Jul 1 02:44:20 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu) - * findvar.c (read_register_bytes, write_register_bytes): - Read spec'd number of bytes from the byte-array `registers'. + * C++: symtab.c: replaced lookup_symtab_1 and lookup_symtab_2 with + a modified lookup_symbol which checks for fields of the current + implied argument `this'. printcmd.c, source.c, symtab.c, + valops.c: Need to change callers once callers are + installed. - * 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. +Wed Jun 29 01:26:56 1988 Peter TerMaat (pete at frosted-flakes.ai.mit.edu) - * findvar.c (value_of_register, read_var_value): - Convert register values and values of register variables - from raw format to virtual format. + * C++: eval.c, expprint.c, expread.y, expression.h, valarith.c, + Merged code to deal with evaluation of user-defined operators, + member functions, and virtual functions. + binop_must_be_user_defined tests for user-defined binops, + value_x_binop calls the appropriate operator function. - * findvar.c (locate_var_value): Like `read_var_value' but - returns value for variable's address. +Tue Jun 28 02:56:42 1988 Peter TerMaat (pete at frosted-flakes.ai.mit.edu) - * value.h: Add new field VALUE_REGNO to each value. It holds - register number to control virtual-to-raw conversion - for assignments to the value. - - * valops.c (value_assign): Convert data from virtual to raw format - if value came from a register variable. - Use read_register_bytes and write_register_bytes. - - - * infcmd.c (continue_command): Subtract 1 from arg - before setting breakpoint's ignore-count. - - * infcmd.c (jump_command): Query if spec'd line is outside - of the current function. - - * infcmd.c (finish_command): Now finish the selected frame, - and no arg required. - - * infcmd.c (set_environment_command): Allow space to separate - varname and value. - - * infcmd.c (registers_info): Print both raw and virtual data - format if they differ. Allow register name as arg. - Ask for a Newline each 16 registers. - - * inflow.c (kill_inferior): call mark_breakpoints_out. - * inflow.c ({fetch,store}_inferior_registers for Sun): - Get the fp registers and store them in right places in - `registers'. - * inflow.c ({read,write}_inferior_register): Deleted. - - * infrun.c (wait_for_inferior): Single-stepping is not considered - to have hit a breakpoint unless the pc before the step matches the - address of the breakpoint.
