1eeba68641 Merged in latest RS6000 diffs from Metin G. Ozisik. 1992-03-29 22:33:35 +00:00

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.

80d68b1d49 * coffread.c, mipsread.c, xcoffread.c, coffread.c, dbxread.c,
elfread.c (coff_symfile_finish):  Add function, prototype, and
	add to the xxxx_sym_fns struct for each file type.  Also reformat
	the xxxx_sym_fns vector to a standard format and add comments.
	* coffread.c, mipsread.c, xcoffread.c, coffread.c, dbxread.c,
	elfread.c (xxx_symfile_new_init, xxx_symfile_init, xxx_symfile_read):
	Pass pointer to struct objfile rather than pointer to sym_fns.
	Change references inside each function accordingly.  Allocate any
	symbol file specific info in the per-objfile memory region.
	* dbxread.c (free_and_init_header_files):  Break function into
	free_header_files(), called from dbx_symfile_finish(), and
	init_header_files(), called from dbx_new_init().
	* dbxread.c (dbx_new_init):  Move deallocation things to new
	dbx_symfile_finish function.
	* elfread.c (elf_new_init):  Call buildsym_new_init().
	* objfiles.c (free_objfile): Call the appropriate symfile_finish()
	routine for the objfile before deallocating other stuff.
	* sparc-tdep.c (get_longjmp_target):  Cast target_read_memory arg.
	* symfile.h:  Move struct sym_fns to before struct objfile def.
	Add sym_finish function pointer and change prototypes of other
	function pointers to reflect passing struct objfile pointer rather
	than struct sym_fns pointer.
	* symfile.c:  Remove now obsolete symtab_fns pointer.
	* symfile.c (symfile_init):  Renamed to find_sym_fns, and now only
	locates the correct sym_fns struct for the given objfile.
	* symfile.c (syms_from_objfile, symbol_file_add):  Restructured
	for better support of mapped symbol tables.
	* symfile.c (symbol_file_command):  Remove obsolete code using
	symfile_fns.
	* symfile.h:  Remove duplicate declarations for symfile_objfile,
	entry_point, and object_files.
	* target.c (target_info):  Compare symfile_objfile to NULL.
	* xcoffread.c (aixcoff_new_init):  Move deallocation stuff to
	aixcoff_symfile_finish().

3531811073 * symfile.c (symbol_file_command): strcmp => !strcmp.
* breakpoint.h:  Move prototypes to follow enum definition they need.
* breakpoint.c, infrun.c:  Lint.
* printcmd.c:  Use `enum enable' rather than `enum
display_status'.
* mipsread.c:  First pass at making it compile with the new
objfile changes.  Probably seriously broken still, but it
compiles.  FIXME.

30875e1c4b * infrun.c, infcmd.c, breakpoint.c, main.c, symfile.c,
breakpoint.h, tm-sun4os4.h, tm-sparc.h, sparc-tdep.c, tm-mips.h,
mips-tdep.h, tm-sun3.h, tm-68k.h, m68k-tdep.h:  Add support for
stepping (and nexting) through longjmp().  Also, cleanup
breakpoint handling quite a bit by creating explicit breakpoint
types instead of using magic breakpoint numbers.

formatting.

c9bd6710ad * mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
filename with error messages.

to avoid "fr" and "fra" having nonunique completions.
* symfile.c (sort_symtab_syms):  Ignore sort of zero symtab *.
(symfile_init):  Print file format name when unable to handle it.
(free_named_symtabs):  Use BLOCKVECTOR rather than obsolete BLOCKLIST.

been read in, particularly for VxWorks.
