* partial-stab.h: valu should be a CORE_ADDR.
2001-08-14 H.J. Lu (hjl@gnu.org)
* dbxread.c (SWAP_SYMBOL): Removed.
(INTERNALIZE_SYMBOL): Check sign extended vma.
CUR_SYMBOL_VALUE as CORE_ADDR instead of long
* buildsym.[ch]: export pending_blocks list
* tm-txvu.h: define TARGET_READ_SP and TARGET_WRITE_SP
* txvu-tdep.c: rewrite symtabs to support N_FUN symbols in overlays.
(Actually, the last version did this for N_SLINE symbols).
(txvu_read_sp,txvu_write_sp): new
reading stabs extensions for live range information.
* stabsread.h, partial-stab.h: Add prototypes for new functions.
* symtab.h: Add structure for storing live range information.
* partial-stab.h (case N_BINCL): detect missing partial symtab.
* dbxread.c: Add a complaint for N_BINCL without a corresponding
partial symtab. Remove earlier change of 5/27/97.
external forms may have different sizes. Don't assume that an
internal_nlist has the same layout as an external_nlist. Create
symbol for n_strx element so to hide specifics of nlist from
partial-stab.h.
* partial-stab.h: Don't reference dbxread symbols directly. Use
CUR_SYMBOL_STRX instead.
* config/i386/xm-windows.h: Define SIGQUIT and SIGTRAP.
* config/v850/tm-v850.h: Define PS_REGNUM and TARGET_V850 for
MSVC builds.

use partial_symtab->textlow==0 as a flag, as 0 is a legitimate
text address. Use a seperate flag (textlow_not_set) instead.
This makes stabs in ELF .o files work a lot better.

partial-stab.h.
* stabsread.h (end_psymtab): Add textlow_not_set arg to prototype.
(add_psymbol_to_list): Add an arg for passing CORE_ADDR values and
use it, rather than calling add_psymbol_addr_to_list.
(add_psymbol_addr_to_list): Delete.
(add_psymbol_to_list): Make psymbol static to avoid random data in
gaps due to alignment of structure members.
* symfile.h (INLINE_ADD_PSYMBOL, ADD_PSYMBOL_TO_LIST,
ADD_PSYMBOL_ADDR_TO_LIST): Remove. Real world tests show no
performance improvements by inlining via complicated macros and
they just make gdb larger and harder to maintain.
* dwarfread.c (add_enum_psymbol): Replace ADD_PSYMBOL_TO_LIST
and/or ADD_PSYMBOL_ADDR_TO_LIST macro(s) with call to
add_psymbol_to_list with appropriate long or CORE_ADDR args.

pst->textlow if the function symbol value is zero.
* stabsread.c (define_symbol): Initialize SYMBOL_TYPE field
for function prototype declaration symbols.

callers/references changed.
* dbxread.c (read_ofile_symtab): Correctly determine value for
last_source_start_addr for reordered executables.
(process_one_symbol): Handle N_FUN with no name as an end of
function marker.
* partial-stab.h (case N_FN, N_TEXT): Don't assume CUR_SYMBOL_VALUE
is the high text address for a psymtab.
(case N_SO): Likewise.
(case N_FUN): Handle N_FUN with no name as an end of function
marker.
* minsyms.c (lookup_minimal_symbol_by_pc): Examine all symbols
at the same address rather than a random subset of them.

* elfread.c (elf_symfile_init): Similarly.
* somread.c (som_symfile_init): Similarly.
* xcoffread.c (xcoff_symfile_init): Similarly.
Support for debugging reordered executables. Remaining mentor vm
changes.

specific to aix4 support on the rs6000.
* config/rs6000/tm-rs6000.h (CONVERT_FROM_FUNC_PTR_ADDR): Don't
do the conversion if the pointer is not a magic aix function
pointer.

(is_magic_function_pointer): New function.
* rs6000-tdep.c (skip_prologue): Refine check for frameless
functions. Handle b .+4 emitted by aix4 compilers. Only
allow one load of a minimal toc pointer. Handle aix4 compiler's
code for alloca.
* rs6000-tdep.c (find_toc_address): Report an error if no toc was
found rather than possibly core dumping.
* partial-stab.h: Handle extra field generated by the aix4 compiler
for enumerations.
* stabsread.c (read_enum_type): Likewise.
* xcoffsolib.c (sharedlibrary_command): New command.

core_ops to current_target after adding the shared libraries.
* partial-stab.h (N_EXCL), dbxread.c (add_old_header_file,
find_corresponding_bincl_psymtab): Change `repeated header not seen'
error to a complaint, simplify complaint.

history chain until we are sure there won't be an error.
* Add rule for annotate.o to keep Sun make happy.
* configure.in: Add config for powerpc/Netware.
* partial-stab.h (near N_SO): Don't call START_PSYMTAB with null
filename. This speeds up handling of trailing N_SO stabs (they
mark the end of a .o file).
* target.c, target.h: Change the way pushing and popping of
targets work to support target overlays and inheritance.
* corelow.c, hppa-tdep.c, inflow.c, remote-nindy.c, utils.c:
Fixup references to current_target, due to previous changes.

* dbxread.c (read_dbx_symtab): Remove unused variable
end_of_text_address. Relocate text_addr when passing it
to end_psymtab.

library functions before the executable is run. Retrieve dynamic
symbols from stripped executables.
* mipsread.c (read_alphacoff_dynamic_symtab): New function.
* mipsread.c (mipscoff_symfile_read): Use it. Issue warning message
if no debugging symbols were found.

Use it.
* utils.c, defs.h (gdb_print_address): New function.
* expprint (dump_expression), gdbtypes.h: Use it.
* breakpoint.c (describe_other_breakpoints),
symmisc.c (dump_symtab, print_symbol):
Use filtered not unfiltered I/O.
(remove_breakpoints): Remove BREAKPOINT_DEBUG code. Might as well
just run gdb under a debugger for this (and it had problems with
printing addresses, how to print b->shadow, etc.).
* buildsym.c (make_blockvector), core.c (memory_error),
exec.c (print_section_info), maint.c (print_section_table),
mdebugread.c (parse_procedure), solib.c, source.c, symfile.c,
symmisc.c, symtab.c, valops.c, valprint.c, xcoffexec.c:
Add comments saying code is broken. Marked with "FIXME-32x64".

to print the symbol name.
* stabsread.c (define_symbol): Handle cfront lossage for
struct/union/enums and typedefs.
* partial-stab.h (case N_BINCL): Update psymtab_language
as appropriate when changing subfiles.
(case N_SOL): Update psymtab_language as appropriate when
changing subfiles. Add typedef for structs, unions, and enums
when processing C++ files.
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.
