properly for n64.
(elf_machine_runtime_setup): Cast link_map pointer to Elf Addr
type.
(elf_machine_rel, elf_machine_rel_relative): Cast symidx to Elf
Word before comparing with gotsym. Take reloc_addr argument as
void*. Remove the code added for the compiler to drop any
alignment assumptions.
(elf_machine_matches_host): Prevent linking of o32 and n32
together.
(elf_machine_dynamic): Document assumption on $gp.
(STRINGXP, STRINGXV, STRINGV_): New macros.
(elf_machine_load_address): Use them to stringize PTR_LA and
PTR_SUBU.
(ELF_DL_FRAME_SIZE, ELF_DL_SAVE_ARG_REGS,
ELF_DL_RESTORE_ARG_REGS, IFABIO32): New macros used in...
(_dl_runtime_resolve): Adjust it for all 3 ABIs.
(__dl_runtime_resolve): Cast the symtab initializer to the
right type.
(RTLD_START): Use it. Adjust it for all 3 ABIs.
(elf_machine_rel): Mark as always_inline in RTLD_BOOTSTRAP.
Handle 64-bit R_MIPS_REL composite relocation and accept
R_MIPS_64 relocations to shift addend size to 64 bits.
Document assumption regarding local GOT entries. Document
backward-compatibility departing from the ABI behavior in
applying relocations that reference section symbols, no longer
used. Support relocations to mis-aligned offsets.
* sysdeps/mips/mips64/dl-machine.h: Deleted, obsolete.

* sysdeps/mips/dl-machine.h (__dl_runtime_resolve): Likewise.

* sysdeps/mips/dl-machine.h (_dl_runtime_resolve): Define $sp as
the frame pointer. Allocate stack space for $a0 for
__dl_runtime_resolve(). Do not save $sp in $s0 as it's
callee-saved anyway.
as function.
(_RTLD_EPILOGUE): Reformat. Declare size of entry function.
(ELF_MACHINE_BEFORE_RTLD_RELOC): Relocate the dynamic linker itself so
it will even work when not loaded to the standard address.
(RTLD_START): Reformat. Call _dl_start in a way that is safe even
before the dynamic linker itself is relocated.
* sysdeps/mips/dl-machine.h (elf_machine_runtime_link_map): Verify
that gpreg really points to the GOT section of the calling object.
Scan all PT_LOAD segments of objects for stub_pc, instead of only
checking a start address of first one.
Fix typos.
* sysdeps/mips/mips64/dl-machine.h (elf_machine_runtime_link_map):
Likewise.
* sysdeps/mips/dl-machine.h (__dl_runtime_resolve): Fix a typo.
* sysdeps/mips/dl-machine.h (elf_machine_got_rel): Optimize a bit
as suggested by Ulrich Drepper.
(__dl_runtime_resolve): Remove unused variable, initialize sym
directly.
(RTLD_START): Document OFFSET_GP_GOT.
(OFFSET_GP_GOT): New magic value.
(elf_mips_got_from_gpreg): Use OFFSET_GP_GOT.
(elf_machine_got_rel): Only declare strtab if needed.
* sysdeps/mips/dl-machine.h (__start): Rewritten for 2.2 startup
conventions.
(elf_machine_rel): Use R_MIPS_REL32 for RESOLVE.
(elf_machine_runtime_setup,elf_machine_got_rel): Move at end of
file and make dependend on RESOLVE.
(ELF_MACHINE_RUNTIME_TRAMPOLINE): Fix arguments to _dl_lookup_symbol.
(RESOLVE_GOTSYM): Fix arguments to _dl_lookup_symbol.
* sysdeps/mips/dl-machine.h (elf_machine_matches_host): Follow
change from 1999-10-07 to elf/elf.h and rename EM_MIPS_RS4_BE to
EM_MIPS_RS3_LE.
* sysdeps/mips/mips64/dl-machine.h: Likewise.
(elf_machine_got): Removed, not needed anymore.
(ELF_MACHINE_RELOC_NOPLT): Removed.
(ELF_MACHINE_JMP_SLOT): Added.
(_RTLD_PROLOGUE): We use gcc, no need to check for __STDC__.
(_RTLD_EPILOGUE): Likewise.
(RESOLVE_GOTSYM): Use R_MIPS_REL32.
(ELF_MACHINE_RUNTIME_TRAMPOLINE): Likewise.
