as a destination, not a floating point register. From Christian
Kuehnke <Christian.Kuehnke@arbi.Informatik.Uni-Oldenburg.DE>.

unconditionally_kill_inferior): Undo Oct 26 1996 and Apr 26 1997
changes to trace PRFS_STOPTERM and handle PR_DEAD.
These changes tried to work around a problem with an early DU 4.0
release, but they trigger subtle timing dependent kernel bugs
in older OSF/1 releases.

Also a couple of warning and formatting fixes.

stepping over an instruction that triggered a watchpoint.
* remote-mips.c: Numerous changes to support hardware breakpoints
and watchpoints on LSI MiniRISC and TinyRISC boards.
* mips-tdep.c: Move MIPS16-related macros to config/mips/tm-mips.h.
(mips_breakpoint_from_pc): Account for different breakpoint
instructions used by PMON and IDT monitor.
* config/mips/tm-embed.h: Enable hardware breakpoints on embedded
MIPS targets.
* config/mips/tm-mips.h: Define breakpoint instructions for
PMON and IDT monitor. Move MIPS16-related macros here from
mips-tdep.c.

initialize.
(default_gdb_init): New procedure; allow gdb_init to be overridden
by a target configuration file.
(gdb_expect): Pass the timeout to remote_expect.
* config/dos.exp(dos_wait): Add timeout parameter.
* lib/remote.exp(remote_expect): Add timeout parameter.
(remote_wait): Ditto.
(standard_wait): Ditto. Also give up if the program outputs
more than 512,000 bytes.
* config/vxworks.exp: Use timeout parameter instead of setting
timeout variable.
* config/dos.exp: Ditto.
* config/ddb.exp: Ditto.
* lib/mondfe.exp: Ditto.
* lib/rlogin.exp: Ditto.
* lib/telnet.exp: Ditto.

* config/gdb-comm.exp: Ditto.
* config/gdb_stub.exp: Ditto.
* config/i960.exp: Ditto.
* config/ddb-ether.exp: Ditto.
* config/sim.exp: Ditto.
* lib/g++.exp(g++_init): Use g++_include_flags instead of making
up the includes ourselves.

* scripttempl/elfppc.sc: Correct .rela.sdata entries.
* scripttempl/elfppc.sc: Put the PLT between the small and large
BSS segments.
* emulparams/elf32ppc.sh (TEXT_START_ADDR): The ABI says `A
program base of 0x02000000 is recommended...' because otherwise
shared libraries are less efficient. We use 0x01800000 because
otherwise it's impossible to branch to location 0, for instance if
you have an undefined weak symbol.
|
|
* config/tc-ppc.h (tc_fix_adjustable): Don't let the assembler
calculate relocations to any external symbol, because we might be
linking a shared object and the symbol might be overriden or moved
(for instance, moved into a static executable's .bss section).
(GLOBAL_OFFSET_TABLE_NAME): Delete. This is an i386 wierdness.
* config/tc-ppc.h (tc_fix_adjustable): GOT-based relocations can't
be calculated by the assembler.
* config/tc-ppc.c (md_apply_fix3): Handle @plt or @local branch
whose destination lies in the same file, by ignoring the @plt or
@local and aiming the branch at its destination.

* mh-ppcpic: New file.
* mt-ppcpic: New file.

* elf32-ppc.c (ppc_elf_relocate_section): Don't emit R_PPC_REL*
relocs in shared libraries which refer to local symbols. Cope
with addend when processing a GOT relocation.
* elf32-ppc.c (ppc_elf_size_dynamic_sections): Only create symbols
for sections that the linker didn't create.
(ppc_elf_finish_dynamic_sections): Only try to write out a section
symbol if it was created in ppc_elf_size_dynamic_sections.
(ppc_elf_relocate_section): Complain if we have to generate a reloc
relative to a section for which we didn't output a symbol.
* elf32-ppc.c (ppc_elf_size_dynamic_sections): Clean up. PLT
relocs are 'rela' relocs, like everything else. .rela.plt is not
a read-only section, so we don't have to special-case it.
* elf32-ppc.c (ppc_elf_adjust_dynamic_symbol): Entries in the
.rela.bss section are (of course) 'rela' relocs not 'rel' relocs.
* elf32-ppc.c (ppc_elf_check_relocs): Initialise srelgot.
(ppc_elf_relocate_section): @got offsets are 4 from start of the
actual .got section.
* elflink.c (_bfd_elf_create_got_section): The three reserved
words start from the symbol '_GLOBAL_OFFSET_TABLE_'.
* elf32-ppc.c (ppc_elf_size_dynamic_sections): '.rela' is 5
characters, not 4.
* elf32-ppc.c (ppc_elf_check_relocs): Use
_bfd_elf_create_got_section to create the GOT rather than
ppc_elf_create_linker_section. Create the '.rela.got' section
ourselves.
(ppc_elf_finish_dynamic_symbol): Set up GOT relocations when a
symbol has a GOT entry.
(ppc_elf_relocate_section): Record when a symbol is used through
the GOT, and allocate space in the GOT for each such symbol.
(ppc_elf_adjust_dynamic_symbol): Delete unused .got.plt stuff.
(ppc_elf_create_linker_section): Delete unused LINKER_SECTION_GOT
stuff.
* elf32-ppc.c (ppc_elf_howto_raw): GOT16_HA relocs should be
treated in a similar way to ADDR16_HA relocs.
(ppc_elf_relocate_section): PLTREL24 relocs do not get copied into
shared objects; the linker must deal with them.
(ppc_elf_create_linker_section): Stop setting
_GLOBAL_OFFSET_TABLE_ to the wrong value; delete unused
LINKER_SECTION_PLT stuff.
(ppc_elf_check_relocs): Delete unused LINKER_SECTION_PLT stuff.
(ppc_elf_finish_dynamic_sections): Use BFD calls to get GOT
section, not ELF-specific calls.
(elf_backend_plt_not_loaded): Set to 1.
(elf_backend_got_symbol_offset): Set to 4.
* elf-bfd.h (elf_backend_data): Add 'plt_not_loaded' member
for when ld.so fills in the PLT; and 'got_symbol_offset' member.
* elflink.c (_bfd_elf_create_dynamic_sections): Apply
plt_not_loaded member.
(_bfd_elf_create_got_section): Apply got_symbol_offset.
* elfxx-target.h (elf_backend_plt_not_loaded): Set default to
'loaded'.
(elf_backend_G_O_T_offset): Set default to 0.
(elfNN_bed): Set added fields.
* elf32-ppc.c (ppc_elf_size_dynamic_sections): Was setting
DT_RELENT in shared objects; should be DT_RELAENT.
* elf32-ppc.c (ppc_elf_relocate_section): Propagate
R_PPC_ADDR16_HA relocs to shared objects. Cope with case where
such a reloc (in a non-shared object) refers to a symbol that's
not defined.

* elf64-mips.c (mips_elf64_swap_reloca_in): Use
bfd_h_get_signed_64 to set the r_addend field.
