[deliverable/binutils-gdb.git] / gdb / ChangeLog

Thu Oct 24 09:33:44 1991  John Gilmore  (gnu at cygnus.com)

	* stack.c (frame_command):  Always print.  Use new
	frame_select_command to select a frame without printing.	

	* dwarfread.c:  Use <varargs.h>, since <stdarg.h> is not portable.

Thu Oct 24 01:32:51 1991  Fred Fish  (fnf at cygnus.com)

        * dwarfread.c: New file for DWARF debugging format support.

	* elfread.c: New file for ELF object file format support.

	* procfs.c: New file for SVR4 /proc (process file system) support.

	* tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
	Amiga UNIX support.

	* xm-svr4.h, tm-svr4.h: New files for SVR4 support.

	* xm-m68k.h: New file for host machines with m68k cpu.

	* Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
	Add elfread.o and dwarfread.o to OBS.

	* symfile.h: Add "elf" to list of supported formats in comment.

	* c-exp.y, defs.h, symtab.h, valprint.c:  Add three new builtin
	types to gdb, builtin_type_long_double, builtin_type_complex, and
	builtin_type_double_complex.  Add and use new TARGET_SHORT_BIT,
	TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
	TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
	TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
	types on the target machine (ala the existing TARGET_LONG_LONG_BIT).

	* infrun.c:  When using SVR4 /proc interface instead of ptrace(),
	call proc_set_exec_trap() to setup child to stop at first instruction.

	* inftarg.c: When using SVR4 /proc interface, call proc_wait()
	rather than wait().

	* m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
	supply_fpregset(), and fill_fpregset(), which are machine
	dependent support routines for SVR4 /proc interface.

	* utils.c: Add warning_setup() and warning().  Warning() behaves
	the same as error() except that it returns normally rather than
	jumping back to command level.  Modules that don't want to call
	warning() for some reason, but want to produce their own warnings,
	can call warning_setup() to ensure compatibility with the way
	warning() and error() deal with the terminal.

	* symtab.c: Make internal errors produce more useful messages.

	* tm-68k.h: Move code that is duplicated in almost every single
	m68k based machine's configuration files to this common file.
	Duplications in the configuration files still need to be removed
	(FIXME).

	* infrun.c (child_create_inferior): System V versions must call
	setpgrp() with no arguments, to comply with prototyping typically
	in <unistd.h>.

	* munch: Add support for SVR4 style nm output.

	* dbxread.c, mipsread.c symmisc.c, symtab.c:  Remove the object
	file specific fields from the partial symbol table structure and
	replace them with a pointer to private data for each different
	flavor of object file reader to initialize appropriately.

Wed Oct 23 09:38:20 1991  John Gilmore  (gnu at cygnus.com)

	* xconfig/sun[34]os4:  Add note about strstr botch on sunos4.0.3c
	and previous.

	* mipsread.c (fixup_undef_type):  New function.  If a struct /
	union / enum is defined in a header file but nowhere else used,
	(by typedefing, pointer referencing or declaration) the mipsread code
	builds the complete tree for the structure but leaves its code as
	TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
	Guess its type based on the details of the members.

Tue Oct 22 18:04:32 1991  Stu Grossman  (grossman at cygnus.com)

	* infrun.c (wait_for_inferior):  Check return value from
	find_pc_line.

Mon Oct 21 17:47:03 1991  Stu Grossman  (grossman at cygnus.com)

	* infrun.c (wait_for_inferior):  fix stepi/nexti that was broken
	by my last edit to this routine.

Mon Oct 21 14:27:43 1991  John Gilmore  (gnu at cygnus.com)

	* tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
	FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
	the values before putting them into the dummy code.  (From Peter
	Schauer)

Mon Oct 21 10:04:39 1991  Steve Chamberlain  (steve at rtl.cygnus.com)

	* configure.in: added ebmon target.

Wed Oct 16 22:49:58 1991  John Gilmore  (gnu at cygnus.com)

	GDB-4.2 release!

	* Makefile.in:  Roll VERSION to 4.2.
	* README, TODO, WHATS.NEW:  Update.

	* core.c (core_open):  Improve error message for bad file.
	Pass .reg virtual memory address to fetch_core_registers to help
	it find the registers in the core-file header.
	* coredep.c (fetch_core_registers):  Take new argument, use it,
	and pass it to register_addr to locate the block of registers.
	* xm-mips.h:  Update KERNEL_U_ADDR for new scheme.  Cleanup a bit.

	* dbxread.c (read_dbx_symtab, process_one_symbol):  Handle
	Sequent N_FN_SEQ like everybody else's N_FN.

	* main.c:  Circumvent SCO cc bug with #if !!defined(USG).
	* tm-i386v.h:  #endif guck.
	* xconfig/i386*:  Remove -Dgetpagesize()=4096 kludge.
	* xconfig/i386sco:  Add HAVE_STRSTR to avoid ANSI bdeath.
	* xconfig/tahoe:  Add REGEX, which seems to be missing.

	* coredep.c:  Add <sys/types.h> for SCOnix.
	* dbxread.c (read_dbx_symntab):  Avoid coredump on malformed file.
	* printcmd.c (print_formatted):  Flush output before disassembly.

Tue Oct 15 20:12:32 1991  Roland H. Pesch  (pesch at fowanton.cygnus.com)

	* doc/refcard.tex (sec "Working Files"): consistent metavars and
