"rightseg" rather than recalculating. For "symbol OP symbol"
subtract, set "retval" to absolute_section if symbols in same
section.

O_symbol. Simplify a +/- b code. Allow equality and non-equality
comparisons on symbols from any section. Allow other comparison
operators as for subtraction.

(macro): Reflect change to MAX_GPREL_OFFSET.
(mips_ip): Check explicitly against S_EX_NONE.

support for %higher and %highest.
(LP): Remove.
(RP): Remove.

reliable. Add support for %higher and %highest. Further support to
parse %gprel and %neg is implemented but currently deactivated.
-mipsX is specified. Make both -mcpu/-march and -mcpu/-mtune pairs
mutually exclusive (if they are different).

set more than once.
* config/tc-mips.c (mips_fp32, mips_32bit_abi): New static variables.
(md_long_opts): Add -mfp32 option.

used in branch and M_LI_D macros. Use HAVE_64BIT_FPRS to determine
the width registers used in M_LI_DD macros. Use HAVE_32BIT_ADDRESSES
to determine the width of addresses in load, store and jump macros.
(macro2): Use HAVE_32BIT_GPRS to determine the width of registers
used in set instructions; do not check the address size for them.
Use HAVE_32BIT_ADDRESSES to determine the width of addresses in
unaligned load and store macros.
(mips_ip): Use the new macros to check the width of a register when
processing float constants. Force a constant into memory if it is
destined for an FPR and the FPRs are wider than the GPRs. Warn about
odd FPR numbers if HAVE_32BIT_FPRS. Use HAVE_32BIT_GPRS rather
than mips_gp32 to select synthetic instructions.
(macro_build): Use HAVE_32BIT_GPRS rather than mips_gp32 to select
synthetic instructions.
* config/tc-mips.c (md_estimate_size_before_relax): Make sure
we treat weak like extern only for ELF.
(mips_fix_adjustable): Make sure we don't adjust extern/weak
symbols only for ELF.

extern/weak symbols for ELF.

ELF.
(mips_fix_adjustable): Don't adjust extern/weak symbols for
ELF.

* config/tc-mips.c (mips16_mark_labels): Reduce number of calls to
S_GET_VALUE by using a temp.
(append_insn): Likewise, and for S_GET_VALUE too.
(mips_emit_delays): Likewise.
(my_getExpression): Likewise.
(md_apply_fix): Likewise. Use "valueT" rather than "long" for "value".
(mips16_extended_frag): Remove code concerned with avoiding
locking in a frag address now that symbols are not finalized until
relaxation is complete. Cater for first relaxation pass having
bogus addresses. Use relax_marker to reliably determine whether a
symbol frag has been reached on the current pass.
* config/tc-mips.c: Support ELF64 for traditional MIPS targets.
* Makefile.am: (TARG_ENV_HFILES): Add tc-mips.h.
