Except for the two m32r modules, this checkin is for overlay support. * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(), find_pc_sect_function(), find_pc_sect_partial_function(): new functions for debugging overlays; pc without section is ambiguous. * breakpoint.[ch]: add section pointer to breakpoint struct; add section argument to check_duplicates(); check section as well as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(), breakpoint_thread_match(), bpstat_stop_status()]; add section argument to describe_other_breakpoints(); use INIT_SAL() macro to zero-out new sal structures; make resolve_sal_pc() fix up the sal's section as well as its pc; match on section + pc in clear_command() and delete_breakpoint(); account for overlay sections in insert_breakpoints(), remove_breakpoint() and breakpoint_re_set_one(); all this to support overlays where a PC is not unique. * exec.c: change xfer_memory() to handle overlay sections. * findvar.c: change read_var_value() to handle overlay sections. * frame.h: declaration for block_for_pc_sect() [blockframe.c]. * infcmd.c: jump_command() warns against jumping into an overlay that's not in memory. Also use INIT_SAL() to initialize sals. * infrun.c: wait_for_inferior() sets a flag to invalidate cached overlay state information; Also use INIT_SAL() to init sals. * m32r-rom.c: modify load routines to use LMA instead of VMA. * m32r-stub.c: mask exit value down to 8 bits; screen out any memory read/writes in the range 600000 to a00000, and ff680000 to ff800000 (hangs because nothing is mapped there); fix strcpy(). * maint.c: maintenance command "translate-address" supports overlays. * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays. * objfiles.[ch]: add ovly_mapped field to the obj_section struct; this constitutes gdb's internal overlay mapping table. Add macro ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays. Add function find_pc_sect_section(). * printcmd.c: modify print_address_symbolic() with overlay smarts; modify address_info() with overlay smarts; add function sym_info() to support the INFO SYMBOL command (translate address to symbol(s)); modify disassemble_command() to work on unmapped overlays. * source.c: use INIT_SAL() to initialize sals. * symfile.[ch]: change generic_load() to use section's LMA address instead of VMA address, for overlay sections. Add numerous functions for finding a PC's section / overlay, translating between VMA and LMA address ranges, determining if an overlay section is mapped, etc. Add several user commands for overlay debugging. Add support for a "generic" form of automatically reading overlay mapping info from the inferior (based on the default (simple) overlay manager which Cygnus provides as an example). * symtab.[ch]: add functions find_pc_sect_symtab(), find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line() for lookup; modify lookup_symbol and decode_line_1() to use them; modify find_function_start_sal() to account for overlay sections; add macro INIT_SAL() for initializing struct symtab_and_line. * target.c: fix a comment in the declaration of target_ops.

1996-07-13 * objfiles.c (map_to_file): Error return from mmalloc_findbase isFred Fish1-1/+1
a NULL pointer, not a -1. Fix oops from a previous checkin.
1996-07-11 * Makefile.in (MMALLOC_CFLAGS): Eliminate intermediate MMALLOC_DISABLEFred Fish1-3/+48
and MMALLOC_CHECK macros, and add comment indicating how host dependent makefile fragment should modify MMALLOC_CFLAGS to not use mmalloc, or to use it but to not do heap corruption checking. * gdbserver/Makefile.in: Ditto. * utils.c (init_malloc): Replace warning() use with direct call of fprintf_unfiltered, since current_target has not yet been set and thus we cannot use warning(). If we try to use mmcheck and it fails, suggest that this configuration needs NO_MMCHECK or MMCHECK_FORCE defined.

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): Use it. * objfiles.h (rt_common_objfile): New global, points to objfile containing the runtime common minimal symbols. * objfiles.c (free_objfile): Mark rt_common_objfile as unallocated before freeing it. * solib.c (allocate_rt_common_objfile): New routine to allocate an objfile for the runtime common minimal symbols.

(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.

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 /* */. * stabsread.h: Add os9k_stabs variable. * stabsread.c (start_stabs), os9kread.c (os9k_process_one_symbol): Set it. * stabsread.c (define_symbol): If os9k_stabs, put a 'V' symbol descriptor in global_symbols not local_symbols.

objfile->sections is already set. * objfiles.c (add_to_objfile_sections): Check SEC_ALLOC not SEC_LOAD to match recent change to exec.c.
1993-11-01Change the stream argument to _filtered to GDB_FILE *.Thomas Lord1-2/+2
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.
