2670f34d21 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.  See ChangeLog.
1992-07-04 13:59:03 +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.

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.
1992-05-01 09:14:43 +00:00
Stu Grossman
b2de19e3c6 * buildsym.h, dbxread.c, mipsread.c: Add objfile arg to
process_one_symbol.
1992-04-04 01:43:01 +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.

a6f40e9453 Forgot these two from previous check-in of rs6000 stuff. 1992-03-01 01:08:35 +00:00
John Gilmore
1ab3bf1b14 * Check in Fred Fish's changes in these modules. Fred
will make ChangeLog entries for all of them.
1992-02-22 01:46:16 +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
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.

c030245775 Break out symbol-table-building routines
from dbxread.c, so they can be shared with xcoffread.c.
