784fd92b3d * dbxread.c (dbx_symfile_init): Init stab_section_info to NULL to 
prevent crashes when examining cross-targets.
* dbxread.c (process_one_symbol):  Include directory name when
calling start_subfile for SOL & BINCL symbols.  This allows gdb to
find include files, and yacc/lex sources when the cwd doesn't match
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
files.

1304f099bc Small changes from Solaris port. The big stuff is not all working yet. 
* inferior.h (register_valid):  Declare.
* remote-udi.c, rs6000-xdep.c, sparc-xdep.c, tm-rs6000.h:  Remove decl.
* objfiles.h (ALL_OBJFILE_{SYMTABS,PSYMTABS,MSYMBOLS}):  Add
macros for traversing the data structures in a single objfile.
* tm-m88k.h, tm-sparc.h (REGISTER_NAMES):  Remove extra semicolon.
* tm-i960.h (REGISTER_NAMES):  Cosmetic change.
* infcmd.c:  Lint.

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.

mapped symbol file handling, and a couple of other misc small fixes.

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.
(relocate_minimal_symbol):  Move inline to vmap_symtab.
(vmap_symtab):  Replace iteration with ALL_OBJFILES,
iterate_over_msymbols with ALL_MSYMBOLS.

Misc cleanup prior to release.

* dwarfread.c (dwarf_build_psymtabs):  Remove mainline test.
* mipsread.c (compare_symtabs, compare_psymtabs):  Remove, unused.
* mipsread.c:  Add prototypes for all static functions.

* symmisc.c (dump_symtab_lines, dump_symtabs, dump_last_symtab,
dump_blockvector, dump_block, dump_addrchass, dump_namespace,
dump_symbol, dump_type, dump_linetable, dump_strtbl):  Remove, unused.
* xcoffread.c (dump_symtab_lines, dump_symtabs, dump_last_symtab,
dump_blockvector, dump_block, dump_addrchass, dump_namespace,
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.

bf349b77fa Add OBJF_SYMS flag and use it to decide whether or not we have already 
tried to read symbols from a file, for mapped objfiles.  This fixes a
memory leak (actually a constant memory growth) due to reading symbol
files with no debug info and thus generating no psymtabs or symtabs.
Most typically happened with shared libraries.

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.
