newly loaded objects upon a TARGET_WAITKIND_LOADED event.
Rewrite code which determines the TOC address for calling functions
in the inferior under AIX.
* rs6000-nat.c (find_toc_address): New function to determine
the required TOC address from a function address.
(_initialize_core_rs6000): Set up find_toc_address_hook to point
to find_toc_address.
(xcoff_relocate_symtab, xcoff_relocate_core): Remove
add_text_to_loadinfo calls.
(exec_one_dummy_insn): Change pid and status to int to get rid of
compiler warnings.
(xcoff_relocate_symtab): Cast ldi to `int *' when passing it to
ptrace to get rid of compiler warnings.
* rs6000-tdep.c: Add definition for find_toc_address_hook.
(rs6000_fix_call_dummy): If find_toc_address_hook is non zero,
patch TOC address load code in the call dummy with the value
returned from find_toc_address_hook.
(struct loadinfo, loadinfo, loadinfolen,
loadinfotextindex, xcoff_init_loadinfo, free_loadinfo,
xcoff_add_toc_to_loadinfo, add_text_to_loadinfo, find_toc_address):
Remove.
(_initialize_rs6000_tdep): Remove initialization of
coff_add_toc_to_loadinfo_hook and xcoff_init_loadinfo_hook.
* xcoffread.c (coff_add_toc_to_loadinfo_hook,
xcoff_init_loadinfo_hook): Remove.
(struct coff_symfile_info): Add toc_offset field.
(scan_xcoff_symtab): Record toc_offset value in toc_offset field
instead of calling xcoff_add_toc_to_loadinfo_hook.
(get_toc_offset): New function to return the value of the
toc_offset field for an object file.
(xcoff_initial_scan): Remove call of xcoff_init_loadinfo_hook.
* xcoffsolib.h (add_text_to_loadinfo): Remove declaration.
* config/rs6000/tm-rs6000.h: Add declarations for
find_toc_address_hook and get_toc_offset.
* read.c (potable): Add sleb128 and uleb128.
(sizeof_*leb128, output_*leb128, emit_leb128_expr, s_leb128): New
functions.
* read.h: Update prototypes.
* symbols.c (resolve_symbol_value): Streamline quite a bit. Return
the symbol value, add a second FINALIZE argument that prevents
changes from being comitted. Update all callers.
* write.c (cvt_frag_to_fill, relax_segment): Handle rs_leb128.
* doc/as.texinfo: Document the new pseudos.
* ocd.c (ocd_insert_breakpoint, ocd_remove_breakpoint): macro
BDM_BREAKPOINT already has braces around it, remove erroneous ones.
* ser-ocd.c (ocd_write): conditionalize on _WIN32 instead of
__CYGWIN32__
* config/powerpc/tm-ppc-eabi.h: remove BDM_NUM_REGS, BDM_REGMAP
* ppc-bdm.c: move BDM_NUM_REGS, BDM_REGMAP here from tm.h file,
fill in doc fields of bdm_ppc_ops.
(bdm_ppc_fetch_registers): don't ask for invalid registers such
as the MQ or floating point regs not present on ppc 8xx boards
(bdm_ppc_store_registers): don't write those same invalid registers
* config/i386/cygwin32.mh: stop including ocd.o ser-ocd.o
* config/powerpc/ppc-eabi.mt:
* config/powerpc/ppcle-eabi.mt:
* config/powerpc/ppc-sim.mt:
* config/powerpc/ppcle-sim.mt: include ser-ocd.o
* ocd.c: move ocd_write_bytes proto to ocd.h since it is used
by ppc-bdm.c, use OCD_LOG_FILE to help debugging, define
BDM_BREAKPOINT if not defined in tm.h
(ocd_error): add new error cases
(ocd_start_remote): send the OCD_INIT command before
OCD_AYT and OCD_GET_VERSION calls, 80 was correct speed after all
(ocd_write_bytes): no longer static
(ocd_insert_breakpoint): no longer static
(ocd_remove_breakpoint): new
* ocd.h: add protos for ocd_write_bytes, ocd_insert_breakpoint,
and ocd_remove_breakpoint
* ppc-bdm.c: change bdm_ppc_ops so we call ocd_insert_breakpoint
and ocd_remove_breakpoint instead of memory_insert_breakpoint
and memory_remove_breakpoint.
(bdm_ppc_open): after calling ocd_open, modify DER
register so interrupts will drop us into debugging mode, finally
disable the watchdog timer on the board so we don't leave BDM
mode unexpectedly.
* ocd.c: move ocd_write_bytes proto to ocd.h since it is used
by ppc-bdm.c, use OCD_LOG_FILE to help debugging, define
BDM_BREAKPOINT if not defined in tm.h
(ocd_error): add new error cases
(ocd_start_remote): send the OCD_INIT command before
OCD_AYT and OCD_GET_VERSION calls
(ocd_write_bytes): no longer static
(ocd_insert_breakpoint): no longer static
(ocd_remove_breakpoint): new
* ocd.h: add protos for ocd_write_bytes, ocd_insert_breakpoint,
and ocd_remove_breakpoint
* ppc-bdm.c: change bdm_ppc_ops so we call ocd_insert_breakpoint
and ocd_remove_breakpoint instead of memory_insert_breakpoint
and memory_remove_breakpoint.
(bdm_ppc_open): after calling ocd_open, modify DER
