John Gilmore 4c7c6bab1f * dbxread.c (process_one_symbol): Ignore N_MAIN, N_ENDM for Solaris.
* 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.

John Gilmore 0f552c5fc6 * buildsym.c (scan_file_globals): Beware the null file.
Fix from Jim Williams.

* stack.c (return_command):  Evaluate expression *before* popping
off the stack frames!  Fix inspired by Jim Williams.
(up_silently_command, down_silently_command):  No sel frame is error.

* defs.h (memcpy, memset):  Conditionalize decls on
#ifndef MEM_FNS_DECLARED, since DECstation differs.
(alloca):  Break out the STDC and non-STDC alloca cases, to make
it work on old preprocessors as well as "picky ANSI" ones.
* xm-mips.h (memcpy, memset):  Declare, and set MEM_FNS_DECLARED.

* mips-tdep.c (heuristic_proc_start):  Zero arg produces zero.
* utils.c (fputs_demangled):  Rename SLOP since DECstation system
header files define it!

Stu Grossman 50a11e4933 * buildsym.c (read_sun_builtin_type): Handle new FCS Sun CC
compiler feature of putting 'c' into basic type descriptors for
all forms of char.
1992-06-25 22:35:09 +00:00
Fred Fish 4341615d92 * valprint.c (type_print_1): Plug memory leak. Print all
C++ syms as demangled, not just functions.
 	* buildsym.c (read_range_type):  When we find a signed char
 	type, do a lookup of signed char, not plain char.  Plain char's
 	still get looked up as plain char's elsewhere.
1992-06-19 02:43:22 +00:00
John Gilmore 2778e91584 * buildsym.c (define_symbol): Nameless types are now on several
platforms; generalize them and un-ifdef them to make Solaris 2
work.
1992-06-15 08:47:56 +00:00
John Gilmore 0dce456e8d Lint 1992-06-13 05:56:15 +00:00
John Gilmore 93297ea028 * buildsym.h: Add processing_acc_compilation flag.
* buildsym.c (read_sun_builtin_type, read_sun_floating_type):  New.
(define_symbol):  Skip arg types in function entries.  Resolve
overloaded 'P' which acc uses for prototypes of functions called
by this file.
(read_type: 'b', 'r'):  Handle Solaris2 builtin types.

* minsyms.c (prim_record_minimal_symbol_and_info):  Hack to
save size of ELF symbols.  FIXME.
* tm-sun4os5.h:  Rename to tm-sun4sol2.h.  Update defines for Sol2.
* xm-sun4os5.h:  Rename to xm-sun4sol2.h.  Hack more defines.

* config/sun4os5.m[ht]:  Rename to config/sun4sol2.m[ht]; new xm, tm.
1992-06-13 02:18:44 +00:00
John Gilmore ea1549b346 * gdbtypes.c (make_{reference,pointer,function}_type): New
functions which handle overwriting of forward-referenced types
for stabs file reading.
(lookup_{reference,pointer,function}_type):  These just call
the make_*_type functions with a null storage alloc parameter.
* gdbtypes.h (make_{reference,pointer,function}_type):  Declare.
* xcoffread.c (smash_to_pointer_type):  Remove, no longer used.

* buildsym.c (dbx_lookup_type):  Zero result for (-1,-1) arg.
(dbx_alloc_type):  Make it easier to understand.  No funct change.
(define_symbol: 't'):  Don't put the typedef name into the name of
the struct, union, or enum.  Bugfix.
(read_type: '*', '&', 'f'):  Add comments.  Use make_XXX_type
routines to properly handle overwriting preallocated types so that
forward references will work.
(read_enum_type):  Force enum values to file scope, due to bug in
Sun compiler output.  FIXME, fix later.

Remove unused header_file_prev_index mechanism.  It was already
obsolete in gdb-3.5.  These comments appeared in 3.5:
  /* This code was used before I knew about the instance codes.
     My first hypothesis is that it is not necessary now
     that instance codes are handled.  */
* dbxread.c (add_new_header_file):  Remove header_file_prev_index.
* buildsym.h:  Remove it and prev_index that saves it.
* buildsym.c (push_subfile, pop_subfile, start_symtab):  Remove it.

* solib.c (special_symbol_handling):  When called from core files,
must set up debug_addr.  Don't print error messages, just return.
* symmisc.c (print_symbol):  Less ascii diarrhea for enums, please.

1992-04-09 07:57:10 +00:00
John Gilmore 03c93c664d * buildsym.c (read_struct_type): Avoid coredump when C++
abbreviated type name is messed up.  Reported by Joe Buck.
FIXME, we need to determine whether GDB or GCC needs to be
smarter to correctly locate this type name.   p*927 circumvention,
needs real fix when Tiemann's back.
1992-04-02 11:56:14 +00:00

Per Bothner 1eeba68641 Merged in latest RS6000 diffs from Metin G. Ozisik. 1992-03-29 22:33:35 +00:00
John Gilmore c2e4669f8c Misc cleanups from code review. 1992-03-27 23:56:15 +00:00
Michael Tiemann be1384b056 Fixed a place where dbx symbol name continuation was appearing in an
unexpected place, causing the `Trace' type in gperf/main.o to be
mis-parsed.
1992-03-24 15:28:40 +00:00
Fred Fish 5e2e79f859 Many changes, most related to creating entry point information on a per-objfile
basis.  See comments in objfiles.h and details in ChangeLog.  Also remove
redundant definitions of FRAME_CHAIN_VALID from most of the tm-* files and
use a default definition in frame.h.

Michael Tiemann d747e0af3d Tue Mar 3 15:11:52 1992 Michael Tiemann (tiemann@cygnus.com)
* All GDB files that #include defs.h: Removed stdio.h.
	(defs.h): #include stdio.h.

This has been tested by building GDBs for all targets hosted on Sun4.
None of the build problems were related to stdio.h inclusion.  (n.b.
many configurations don't build for other reasons.)

will make ChangeLog entries for all of them.
1992-02-22 01:46:16 +00:00
John Gilmore 256269fc92 * buildsym.c (read_struct_type): Avoid double-bump of parse ptr
in the op$::OPERATOR. case.  From Steven McCanne, <mccanne@horse.ee.lbl.gov>.
1992-02-07 16:23:57 +00:00
John Gilmore 5a4e721505 * buildsym.c (read_struct_type): Circumvent sun3 sunos "--" compiler bug.
* c-exp.y (yylex):  `this' and `template' are only tokens in C++.
* target.c (target_xfer_memory):  Return errno in preference to EIO.
1992-01-27 22:10:05 +00:00
Michael Tiemann 0eb0a82097 Fix demangling of destructors, and fix a minor indentation problem. 1992-01-20 16:55:45 +00:00
Stu Grossman 59d97f7fd7 buildsym.c (cleanup_undefined_types): Add support for enums.
This fixes the 'GDB internal error.  cleanup_undefined_types with
bad type' problem.
1992-01-07 21:16:25 +00:00
Per Bothner aab77d5f23 More changes, mostly cleanups from the last set.
Made some more progress in removing duplicate assembly opcode files.
More improvements to how mipsread and to a lesser extent dbxread work.
See the ChangeLog for details.
1991-12-27 21:11:37 +00:00
Per Bothner 7e258d18e0 Oodles of changes. The most important is adding support for stabs
encapsulated in mips ecoff.  See ChangeLog for the gory details.
1991-12-23 23:16:58 +00:00
Michael Tiemann 7fb4dfc05d Integrated quick fixes to C++ handling of static member functions and
stub methods.  These changes are not complete in that a better
implementation will be more maintainable, but they make it possible to
debug groff with GDB.
1991-12-09 05:20:14 +00:00
Fred Fish c8d9eb8e43 Supply missing parenthesis (~line 1269). 1991-12-05 18:53:46 +00:00

* tm-convex.h, tm-hp300hpux.h, tm-merlin.h, tm-sparc.h,
xm-merlin.h:  Avoid host include files in target descriptions.
* getpagesize.h:  Removed, libiberty copes now.
1991-11-21 18:42:05 +00:00
Michael Tiemann 572acbbedc Make changes needed to handle code which uses ANSI-mangled names (and
new G++ 1.95 dbxout output).
1991-11-18 00:32:34 +00:00
Per Bothner 0e2a896cf5 Fixes related to handling of C++ methods (handle destructors
and parameters that are functions).
1991-11-12 22:20:02 +00:00
John Gilmore 74f6fb084c * Makefile.in: Add xcoffread.c, xcoffexec.c.
* xcoffread.c:  New file for handling AIX mangled-coff files.
* xconfig/rs6000, tconfig/rs6000:  New files.
* buildsym.c:  Add hooks for xcoffread.c.
1991-11-12 15:54:27 +00:00
John Gilmore 19405dda98 Remove Rs/6000 changes (patch_block_stabs) so it will link without. 1991-11-09 11:16:47 +00:00
John Gilmore a048c8f537 Add tracking of object files (that contain symbols) to gdb.
This includes a "struct objfile" that owns symtabs and psymtabs
that were read in from that binary file.  See ChangeLog.
1991-11-09 10:50:07 +00:00
Per Bothner abefb1f107 * infrun.c: Fixed typo in comment.
* utils.c:  All the v*fprintf emulation is now in libiberty,
	so we can get rid of some junk.
	* xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
	xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
	* m68k-pinsn.c (print_insn_arg):  Support BB/BW/BL
	type operands, as used by branch instructions.
	* gmalloc.c: Fix prototype of memcpy.
	* elfread.c: Comment out register_addr, since it conflicts
	with the one in coredep.c.
	* buildsym.h:  Remove extern declarations of two functions
	that are really static in buildsym.c.
	* tm-mips.h: Add symbolic names for more registers.
	* mips-xdep.c (store_inferior_registers): Use new register names.
	* xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
	only used for core files, not ptrace.  Therefore,
	the KERNEL_U_ADDR hack is no longer needed.
	The mapping to ptrace number is now in in mips-xdep.c.
	* mips-xdep.c:  Define REGISTER_PTRACE_ADDR (using the
	mapping from the old REGISTER_U_ADDR), and use it
	in {fetch,store}_inferior_registers.
	* mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
	* mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
	Save/restore FP regs correctly (?).
	* dbxread.c: Remove duplicate define_symbol and type_synonym_name
	(these had been previously moved to buildsym.c).
	Hence, define_symbol becomes extern instead of static.
	* buildsym.c (read_struct_type):  Comment out bogus handling
	of C++ operator methods.  Minor hacking of reading of class
	contexts. Make define_symbol non-static, so dbxread.c can call it.
1991-11-04 23:15:31 +00:00
John Gilmore 4137c5fc0d * buildsym.c: Break out initial malloc sizes.
(record_line):  Record directly in a subfile.  Alloc on demand.
(compare_line_numbers):  Add from xcoffread.c.
(end_symtab):  New params say whether to sort pendings and
linetable.  Patch block stabs if defined.  Shrink linetable before
allocating the symtab.
* buildsym.h:  Delete line_vector* and prev_line_number.  Add
global_stabs and file_stabs for xcoffread.
* dbxread.c (start_subfile):  Move to buildsym.  Change above calls.
* symtab.h:  LINETABLE(symtab) can now be null.  Zap LINELIST.
* symmisc.c, symtab.c:  Cope with null LINETABLEs.
1991-10-27 22:26:02 +00:00
John Gilmore c030245775 Break out symbol-table-building routines
from dbxread.c, so they can be shared with xcoffread.c.
1991-10-26 07:21:30 +00:00
