6c316cfd66 * inflow.c (new_tty): Temporarily ignore SIGTTOU when 
disconnecting from controlling terminal, to avoid gdb hanging
	on SVR4.  Fixes bug reported by Oliver Okrongli.
	* procfs.c (PROC_NAME_FMT):  Change format to match default used
	by system, as suggested by Oliver Okrongli.
	* tm-68k.h (FRAME_FIND_SAVED_REGS):  Apply missing parentheses
	bug fix from Brent Townshend (bst%tt@cam.ORG).
	* c-exp.y (nonempty_typelist):  Fix memory overrun bug reported
	by turlais@rechser.total.fr.
	* dwarfread.c (decode_subscr_data):  Fix bug in calculation of
	length of non-zero lowerbound arrays.  Bug fix from Peggy Fieland.
	* objfiles.h (unlink_objfile):  Add prototype.
	* objfiles.c (unlink_objfile):  Add function.
	* objfiles.c (free_objfile):  Call unlink_objfile.
	* objfiles.c (allocate_objfile):  Call unlink_objfile on newly
	remapped objfiles.  Bug reported by hahn@sunshine.labs.tek.com.
	Also, discard old possibly bogus sf struct.
	* symfile.c (symbol_file_add):  Call init_entry_point_info() and
	find_sym_fns() for remapped symbol files, in case of any changes
	since the last mapping.

* Makefile.in (DEMANGLE_OPTS):  Add, default to -Dnounderscore.
	* configure.in:  Simplify ncr3000 gdb_host logic, add gdb_target.
	* dwarfread.c (struct_type):  Apply fix from Peggy Fieland for
	proper handling of bit fields.
	* gdbtypes.h (struct type):  Clarify use of field.bitpos.
	* symtab.h:  Fix couple of misspellings in comments.
	* value.h (struct value):  Clarify use of bitpos.
	* value.h (unpack_field_as_long):  Change prototype, returns
	LONGEST.
	* values.c (unpack_field_as_long):  Change return type to LONGEST,
	sign extend unpacked fields that are signed, other rewriting.

2d6d969c61 Fix to dwarfread.c to target pointer and target long sizes, fixes for 
mapped symbol file handling, and a couple of other misc small fixes.

13b5a7ff3e Extensive changes to replace swapin() function with target_to_host() 
and fix all usages to be independent of host/target integer size
mismatches.  However, cross debugging will still not work until the
sign extension issue is resolved either by fixing the bfd library
or implementing sign extension in the gdb code.
 1992-04-14 04:09:00 +00:00
Fred Fish
95967e7379 Add swapin() function, and SWAPIN macro that calls it, to do byte swapping 
copies using appropriate bfd routines.

84ffdec2cb Create and use macros for iterating on symtabs, psymtabs, msymbols. 
* minsyms.c (iterate_over_msymbols):  Remove; clunky and slow.
* symfile.h, symtab.h (iterate_over_msymbols):  Remove prototype
* coffread.c (coff_symfile_read):  iterate_over_symtabs => ALL_SYMTABS.
(patch_opaque_types):  Avoid dummy args and result.
* objfiles.c (have_partial_symbols, have_full_symbols,
have_minimal_symbols):  explicit iteration => ALL_OBJFILES; simplify.
(iterate_over_objfiles, iterate_over_symtabs,
iterate_over_psymtabs):  Remove, clunky and slow.
* objfiles.h:  Replace iterate_over_* prototypes with ALL_SYMTABS,
ALL_PSYMTABS, and ALL_MSYMBOLS macros.
* symmisc.c (dump_symtab, dump_psymtab, dump_msymbols,
dump_objfile):  Remove dummy args and results.  Move filename
comparisons to callers.
(printsyms_command, printpsyms_command, printmsyms_command,
printobjfiles_command):  iterate_over_* => ALL_*.  Compare filenames.
* symtab.c (lookup_symtab_1, lookup_symtab, lookup_partial_symtab,
lookup_symbol, find_main_psymtab, find_pc_symtab, sources_info,
list_symbols, make_symbol_completion_list):  Replace explicit
iteration with ALL_SYMTABS, ALL_PSYMTABS, or ALL_MSYMBOLS.
Eliminate Dijkstra flag crap, break out of loops with gotos.
(lookup_symtab_1):  Protect '/' tests from short filenames.
(cplus_mangled_symbol):  Move inline into lookup_symbol.
* xcoffexec.c (relocate_objfile_msymbols):  Remove poor hack.

dump_symbol, dump_type, dump_linetable, dump_strtbl):  Remove 2nd
unused copy!

* buildsym.c (define_symbol):  Handle global register variables
(from Pierre Willard).  Complain if register numbers are too large.

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.
 1992-03-21 01:56:01 +00:00
Fred Fish
318bf84ffe Globs of changes. See the ChangeLog for details. Most related to

* 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.)

93fe4e330e Saberlint.

af21362450 When creating user defined types for subroutine and array types, check 
first to see if a partial type already exists due to a forward reference,
and if so, bash it to fit.

99140c31fe The list_in_scope pointer needs to be initialized to point to a 
valid scope.  Use the file scope as the initial scope.

usages.
 1991-12-27 03:55:12 +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
Fred Fish
f8b76e70b7 Numerous small changes and a complete reorganization of solib.c, to support 
SVR4 shared libraries in a manner very close to the original SunOS support.
See the ChangeLog for details.

Now passes all current gdb test suite tests.
 1991-12-06 19:51:01 +00:00
Fred Fish
5edf98d7a2 Fixes to improve opaque struct/union handling. Still fails to find the 
complete definition for files outside the one containing the complete
definition, if that file has not yet been read in.  (Working on it...)
 1991-12-06 16:37:20 +00:00

7b2a87cab2 * symtab.c (decode_line_1): If SKIP_PROLOGUE leaves us in 
mid-line, be more careful about possibly advancing to the next line.
 1991-12-06 09:22:33 +00:00

 1991-12-06 02:22:10 +00:00
Fred Fish
98618bf78a Arrange for enumeration members to be manipulated in source code order, 
since they are stored in the Dwarf info in reverse order.

4cfd3c4990 Initialize the c++ specific portion of the type structure for union types 
as well as struct types, since gdb attempts to reference that portion for
both types.  Was getting core dumps due to NULL pointer dereferencing.
 1991-11-22 02:30:34 +00:00
John Gilmore

convert to use of variable arg count concat() in libiberty.
 1991-11-12 17:50:14 +00:00

b662efeddc Remove leftover call to do_cleanups() which resulted from a previous change. 
Was being called with a random pointer.
 1991-11-09 21:57:55 +00:00

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
545af6ce07 Add C++ as a separate language. 
Also, fix a C++ problem when looking for methods in super-classes.
(There was confusion between base and derived types.)
 1991-11-06 01:08:21 +00:00
John Gilmore
d47d5315c8 * symfile.c (syms_from_bfd): New routine. 
(add_symbol_file):  Call it to do the real work.
(syms_from_bfd):  Initialize entry_point before calling symfile_init.
* symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
