	* mipsread.c (parse_lines):  Check for cbLine being zero, not
	cbLineOffset.
	* mipsread.c (struct symloc):  Add pst_language.

Jim Kingdon a656507936 Write ChangeLog entry for sef changes.
Remove dbxread.c change; I handle this in BFD by making the name start
with "a.out".

Sean Eric Fagan 05c81f45b4 Add support for netbsd386 (almost-but-not-quite 386bsd). 1993-08-23 07:45:32 +00:00
Peter Schauer 0eb22669dc * breakpoint.c (breakpoint_1): Walk the breakpoint chain to decide if
we have breakpoints or watchpoints as we might have to ignore internal
	breakpoints.

	Fix gdb core dumps after `file newfile' commands.
	* symtab.h, symfile.c (clear_symtab_users):  New routine which
	unconditionally clears symtab users. clear_symtab_users_once
	commented out as it was a noop anyway.
	* objfiles.c (free_objfile):  Don't call clear_symtab_users_once.
	* objfiles.c (free_all_objfiles), symfile.c (new_symfile_objfile),

	(SUN_FIXED_LBRAC_BUG,VARIABLES_INSIDE_BLOCK): Use n_opt_found so
	the right thing happens for both acc and SunOS4 /bin/cc.
1993-06-13 02:26:18 +00:00
Jim Kingdon 574dac8e6d * dbxread.c (process_one_symbol): Rather than having
BLOCK_ADDRESS_FUNCTION_RELATIVE a macro, make it a variable which
	is true if we are doing stabs-in-elf, false otherwise.
	config/sparc/tm-sun4sol2.h: Don't define it.
1993-06-11 21:53:49 +00:00

Fred Fish 69a272c4f6 * dbxread.c (dbx_symfile_init): Make size of the string table
size field a define (DBX_STRINGTAB_SIZE_SIZE).  Ensure that the
	offset to the string table is nonzero and handle the nonexistant
	string table case, should it occur.  Ensure that the string table
	size read from the file is reasonable, with a minimum lower bound
	of DBX_STRINGTAB_SIZE_SIZE instead of zero.

	than the file that is supposed to contain it.
	* symfile.c (syms_from_objfile):  Only complain about configured
	NAMES_HAVE_UNDERSCORE differences between gdb and bfd if the
	current target is the default BFD target.

* dbxread.c, partial-stab.h:  Replace all #ifdef hp9000s800's with
GDB_TARGET_IS_HPPA's.  This is a SERIOUS KLUDGE.  The code needs to all
be ripped out and reimplemented right (see elfread.c).
* tm-hppa.h (GDB_TARGET_IS_HPPA):  Define.
1992-09-26 10:24:26 +00:00
Stu Grossman 1aed676612 * tm-sparc.h, dbxread.c (read_ofile_symtab): Install Jim Wilson's

prevent crashes when examining cross-targets.
* dbxread.c (process_one_symbol):  Include directory name when

that in which the object was compiled.
* objfiles.h (ALL_MSYMBOLS):  Don't seg fault when there are no
msymbols.
* symtab.c (lookup_symtab_1):  Rewrite.  It now handles include

* procfs.c (proc_set_exec_trap): Set run-on-last-close flag on
child processes, to avoid dead ones "hanging around" after GDB exits.
(attach): Always stop the process if it needs it.  Set RLC flag
when attaching running processes, so it will continue if we detach
it, quit, or are killed.
(detach):  Clear faults and set RLC flag to make process run
when we close it.
(open_proc_file):  New `mode' argument for O_RDONLY or O_RDWR.
Callers changed.
(info_proc):  Open process O_RDONLY, so we can see any process,
even those controlled by debuggers.
* tm-sun4sol2.h (SUN_FIXED_LBRAC_BUG):  They did (in Sol 2).
1992-07-05 10:26:53 +00:00
John Gilmore 2af231b836 Relocate symbols using an array of section_offsets, rather than a
single `addr' or `offset'.  This makes Solaris-2 support work, and
permits better VxWorks (and maybe xcoff) support later.

* dbxread.c:  Conforming changes.
(struct dbx_symfile_info):  Move to gdb-stabs.h.
(start_psymtab):  Call elfstab_offset_sections to calculate good
offsets for this source file, based on the ELF symbol table info.
(read_ofile_symtab):  Yank N_CATCH, which is dead.
(process_one_symbol, N_CATCH):  Yank.
(", N_FUN, N_FNAME, N_FN, N_FN_SEQ, N_SO, N_SOL, N_ENTRY):
Relocate with SECT_OFF_TEXT.
(", N_STSYM, N_LCSYM, N_ROSYM):  Grope around in the stab string
to distinguish relocatable from absolute symbols.  Then, if not
absolute, do:
(", N_STSYM, N_DSLINE):  SECT_OFF_DATA.
(", N_LCSYM, N_BSLINE):  SECT_OFF_BSS.
(", N_ROSYM):  SECT_OFF_RODATA.
(elfstab_build_psymtabs):  Caller has allocated dbx_symfile_info.
(dbx_symfile_offsets):  Add to translate addr to offset.

* partial-stab.h:  Ignore N_ENDM.
* elfread.c (elf_symtab_read):  Ignore symbols that don't have a
CODE or DATA section attachment.  This eliminates a lot of random
values from shared libraries, which screw up the ordinary symbols
in the address ranges they happen to overlap.
* buildsym.c (define_symbol):  Eliminate special tests
for function types; move into "function" cases in switch statement.
(define_symbol: 'f', 'F', 'P'):  Process all parameter types
in case they define new type numbers.  But ignore them (FIXME).
('k', 'B'):  Ignore const and volatile if we see them (FIXME).
(read_sun_builtin_type):  Add commentary.

Stu Grossman bf18ac8007 * dbxread.c (dbx_symfile_init): Move more code under hp9000s800
conditional.
* hppabsd-core.c:  Don't include "param.h", include <sys/param.h>
instead.
