hold register masks.
(md_begin): Initialize them to zero.
(append_insn): Update mips_gprmask and mips_cprmask. Also add
register variables pinfo and prev_pinfo.
* config/tc-mips.h (mips_gprmask, mips_cprmask): Declare.
* config/obj-ecoff.c (ecoff_frob_file): If TC_MIPS, set gprmask
and cprmask from mips_gprmask and mips_cprmask.
* config/tc-mips.c (GPOPT): Define if OBJ_ECOFF or OBJ_ELF.
(various): Change all references to GP references to apply if
GPOPT, not if OBJ_ECOFF.
(s_change_sec): Rearrange somewhat. If OBJ_ELF, use .rodata
instead of .rdata. If OBJ_ELF, set section flags for .rodata and
.sdata sections.
(s_frame, s_loc, s_mask): Comment out entire functions, rather
than just body. They're not used anyhow.
* configure.in: Set cpu_type to mips for mips*. Accept
mips-*-elfl* and mips-*-elf*.
* config/tc-mips.c: Include opcode/mips.h rather than
mips-opcode.h.
(append_insn): An extra NOP is only needed after instructions
which set HI or LO, not after instructions which read it.
(macro_build, mips_ip): Support new 'E', 'G' and 'B' arguments.
(macro): cfc1 and ctc1 now take "t,G" rather than "t,d".
* config/tc-mips.h (struct mips_opcode): Don't define.
* config/mips-big.mt, config/mips-lit.mt (TARG_CPU_DEPENDENTS):
Set to $(srcdir)/../include/opcode/mips.h.
Get the MIPS assembler up to speed with other gas changes:
* config/obj-ecoff.c (ecoff_set_vma, ecoff_frob_symbol):
Removed; don't change the symbol value.
(ecoff_build_symbols, ecoff_build_procs, ecoff_frob_file): Use
bfd_asymbol_value rather than S_GET_VALUE to include section
vma in symbol value.
(ecoff_frob_file): Ignore BSF_SECTION_SYM symbols, since ECOFF
doesn't output them. Set the vma of sections.
* config/obj-ecoff.h: Don't define obj_frob_symbol.
* config/tc-mips.c (tc_gen_reloc): Adjustment by section vma is no
longer necessary.
(various): use valueT rather than long.
* as.c (perform_an_assemly_pass): Don't set output_section here.
* expr.c (expr_part, expr): Turn off section assertions for ECOFF,
since it has additional sections.
* read.c (s_lcomm): For MIPS ECOFF, put small objects in .sbss,
not bss_section.
* config/obj-ecoff.h (TARGET_SYMBOL_FIELDS): Added
ecoff_undefined field.
* config/obj-ecoff.c (obj_symbol_new_hook): Initialize
ecoff_undefined field.
(add_file): If using stabs, just output a stabs symbol rather than
creating a new fdr.
(obj_ecoff_begin, obj_ecoff_bend): Ignore line number by reading
it with get_absolute_expression, rather than skipping it by hand.
(obj_ecoff_loc): If using stabs, just output a stabs symbol rather
than ECOFF line number information.
(obj_ecoff_stab): Accept non-zero values for stabs line number.
(ecoff_build_symbols): Set ifilesym correctly. Set storage class
to small, undefined and/or readonly sections if appropriate.
Don't output symbol names containing \001 characters.
(ecoff_frob_file): Make sure at least one fdr is output.
* config/tc-mips.h: Define TC_MIPS.
* config/tc-mips.c (g_switch_value): New static variable.
(md_assemble): Set gp size of output BFD.
(gp_reference): New function; returns 1 if expression can be
accesssed via gp. Always returns 0 if not using ECOFF.
(macro_build): Convert BFD_RELOC_LO16 to BFD_RELOC_MIPS_GPREL if
possible.
(macro): Generate sequences using gp if possible.
(md_parse_option): Ignore -EL and -EB. Parse -G.
(md_apply_fix): Added BFD_RELOC_MIPS_GPREL to ignored case.
(s_change_sec): Handle .rdata and .sdata for ECOFF.
(s_extern): Mark symbol as external. Set ecoff_undefined field.
