find_pc_sect_function(), find_pc_sect_partial_function(): new
functions for debugging overlays; pc without section is ambiguous.

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()

instead of VMA address, for overlay sections.

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;

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,

defined. Other small mmalloc related cleanups.

to partial symbol.

bcache statistics.

make_symbol_completion_list):
Account for change to pointer to pointer to partial symbol.
* symtab.h (bcache.h): Include.
* xcoffread.c (xcoff_start_psymtab): Make global_syms & static_syms

symbol tables so that it is obvious that they are not supported on
this particular machine rather than implying they are not supported
at all in this version of gdb.
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):
Use it.

containing the runtime common minimal symbols.

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.

parse_lines): Pass section_offsets info to these routines so that
we can relocate symbol table entries upon readin.
* (psymtab_to_symtab_1): Set symtab->primary to tell
objfile_relocate to do relocations for our symbols.
* (ecoff_relocate_efi): New routine to relocate adr field of PDRs
(which hang off of the symbol table).
* Use prim_record_minimal_symbols_and_info instead of
prim_record_minimal_symbols to supply section info to make minimal
symbol relocations work.
* minsyms.c (prim_record_minimal_symbols_and_info): If section is
-1, try to deduce it from ms_type.

appropriate. Handle relocation of MIPS_EFI symbols special. Also,
add code to relocate objfile->sections data structure.
* remote.c (get_offsets): Use new protocol message to acquire

VM_MIN_ADDRESS.
* config/alpha/tm-alphanw.h: DECR_PC_AFTER_BREAK=0, VM_MIN_ADDRESS=0.

and means that these filenames no longer need be unique across all
the config/* directories.
* configure.in: Put the config/*/ into TM_FILE, etc.
* m68k-stub.c (computeSignal): Return SIGFPE, not SIGURG, for chk
and trapv exceptions.
* target.h (struct section_table), objfiles.h (struct obj_section):
Change name of field sec_ptr to the_bfd_section. More mnemonic
and avoids the (sort of, for the ptx compiler) name clash with
the name of the typedef.

solib.c, irix5-nat.c, objfiles.c, remote.c: Change users.

* Makefile.in (utils.o): Add dependency.
* remote.c (getpkt): Add support for run-length encoding.
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.

change), so that -readnow and -mapped can appear anywhere.
Make text_relocation a local variable.

enumeration constant.
(os9k_init_type_vector): New function.
(dbx_lookup_type): Call it when starting new type vector.

ChangeLog objfiles.c objfiles.h symfile.c target.c main.c
Makefile.in configure.in
Added Files:
os9kread.c os9kstab.c remote-os9k.c
* os9kread.c: New file to read os9000 style symbo table.
* os9kstab.c: new file to read os9000 style stabs.
* remote-os9k.c: remote protocol talking to os9000 rombug monitor.
* objfiles.c (find_pc_objfile): new function to search objfile
from pc.
* objfiles.c (objfile_relocate_data): new function to relocate
data symbols in symbol table.
* objfiles.h: Add two aux fields in struct objfile to handle
multiple symbol table files situation like in os9000.
* symfile.c: Change so 'symbol-file' command can handle multiple
files. Also call target_link() to get relocation infos.
* target.c (target_link): new function to get relocation info when
a symbol file is requested to load.
* main.c (quit_command): take out 'inferior_pid != 0' condition,
because in cross mode there's no inferior pid, bit they need to
be detached.
Makefile.in: add os9kread.c os9kstab.c and .o's.
configure.in: add i386os9k target.
config/i386/i386os9k.mt: new add.
config/i386/tm-i386os9k.h: new add.
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.
right operations ourself, rather than calling symbol_file_command.
If we re-read something, call clear_symtab_users not just
breakpoint_re_set.
* objfiles.h, objfiles.c (build_objfile_section_table): No longer
static.
* symfile.c (clear_symtab_users): Call clear_pc_function_cache.
* coffread.c, dbxread.c, elfread.c, mipsread.c, nlmread.c, paread.c
(*_symfile_offsets): Set objfile->num_sections.
* remote.c (remote_wait), symfile.c (syms_from_objfile):
Don't muck with objfile->num_sections now that all the symbol
readers set it.
* elfread.c: Clean up obsolete comment about handling only DWARF.
* paread.c: Remove comment about how we should use an "ordinary"
file format with an hppa suffix. There is nothing ordinary about SOM.
