1995-11-21 18:19:23 +00:00
Fred Fish
e7b6403a67 * objfiles.c (allocate_objfile): Change warning message about mapped

dee803840d * top.c, utils.c, main.c: Replace error_pre_print with two
variables: error_pre_print (for RETURN_ERROR) and quit_pre_print
	(for RETURN_QUIT).  Fixes a bug whereby typing ^C (e.g. in "maint

	* objfiles.c: Don't declare error_pre_print; defs.h does it.
1995-04-04 20:07:21 +00:00
Peter Schauer
02b40a193e * dbxread.c (process_one_symbol): Handle N_FUN symbols
for Sun acc 3.0 under SunOS4.

	Changes to improve handling of runtime common symbols
	under SunOS4.
	* minsyms.c (get_symbol_leading_char):  New routine to determine
	the leading symbol character for an objfile.
	(prim_record_minimal_symbol_and_info, install_minimal_symbols):

	common symbols if necessary and put common symbols into it.
	Clean up code and comments.
	(solib_add, special_symbol_handling):  Cleanup comments regarding
	runtime common symbols.
	* stabsread.c (scan_file_globals_1):  New routine, contains
	old scan_file_globals code. Checks if there are any unresolved
	global symbols before starting the expensive minimal symbol table
	search.
	(scan_file_globals):  Now calls scan_file_globals_1 for the passed
	objfile and eventually for the runtime common objfile. Complains
	about any unresolved global symbols and removes them from the
	global symbol chain to avoid dangling pointers into the symbol
	table if the symbol table is reread.

Jim Kingdon
94d4b71373 * Makefile.in (TAGS): Use variables directly, rather than using
find, to locate TM_FILE, XM_FILE, and NAT_FILE.  This is faster
	and means that these filenames no longer need be unique across all
	the config/* directories.

	and trapv exceptions.

	Change name of field sec_ptr to the_bfd_section.  More mnemonic
	and avoids the (sort of, for the ptx compiler) name clash with

VARIABLES_INSIDE_BLOCK to OS9K_VARIABLES_INSIDE_BLOCK.
	* symfile.c (symbol_file_command): Check for (CORE_ADDR)-1, not
	(CORE_ADDR)0, from target_link, since that is what it uses.
	Process name at end, not during parsing (like we did before Kung's
	change), so that -readnow and -mapped can appear anywhere.
	Make text_relocation a local variable.
	* config/i386/i386os9k.mt: Fix comment.
	* Makefile.in (ALLDEPFILES): Add remote-os9k.c.
	* os9kread.c: Put "comments" after #endif inside /* */.

	descriptors.
	(read_type): If os9k_stabs, accept function parameters after 'f'
	type descriptor.
	(read_array_type): If os9k_stabs, don't expect index type and
	expect lower and upper to be separated by ',' not ';'.
	(read_enum_type): If os9k_stabs, read a number before the first
	enumeration constant.
	(os9k_init_type_vector): New function.
	(dbx_lookup_type): Call it when starting new type vector.
	* config/i386/tm-i386os9k.h: Define BELIEVE_PCC_PROMOTION.
	* (os9k_process_one_symbol): Call define_symbol not os9k_define_symbol.
	* os9kstab.c: Removed.
	* Makefile.in: Update accordingly.
	* objfiles.c (objfile_relocate_data): Removed.
	* remote-os9k.c (rombug_wait): Call objfile_relocate
	not objfile_relocate_data.
	* objfiles.h, objfiles.c: Remove find_pc_objfile.
	* remote-os9k.c (rombug_wait): Call find_pc_section not
	find_pc_objfile.

Thomas Lord
199b2450f6 Change the stream argument to _filtered to GDB_FILE *.
Change all references to stdout/stderr to gdb_stdout/gdb_stderr.

Replace all calls to stdio output functions with calls to
corresponding _unfiltered functions (`fprintf_unfiltered')

Replaced calls to fopen for output to gdb_fopen.

Added sufficient goo to utils.c and defs.h to make the above work.

The net effect is that stdio output functions are only directly used
in utils.c.  Elsewhere, the _unfiltered and _filtered functions and
GDB_FILE type are used.

In the near future, GDB_FILE will stop being equivalant to FILE.

The semantics of some commands has changed in a very subtle way:
called in the right context, they may cause new occurences of
prompt_for_continue() behavior.  The testsuite doesn't notice anything
like this, though.

Please respect this change by not reintroducing stdio output
dependencies in the main body of gdb code.  All output from commands
should go to a GDB_FILE.

Target-specific code can still use stdio directly to communicate with
targets.

	* 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().
