* config/tc-mips.c (RELAX_ENCODE): Remove WARN argument.
(RELAX_FIRST, RELAX_SECOND): Turn into 8-bit quantities.
(RELAX_USE_SECOND): Bump to 0x10000.
(RELAX_SECOND_LONGER, RELAX_NOMACRO, RELAX_DELAY_SLOT): New flags.
(mips_macro_warning): New variable.
(md_assemble): Wrap macro expansion in macro_start() and macro_end().
(s_cpload, s_cpsetup, s_cprestore, s_cpreturn): Likewise.
(relax_close_frag): Set mips_macro_warning.first_frag. Adjust use
of RELAX_ENCODE.
(append_insn): Update mips_macro_warning.sizes.
(macro_start, macro_warning, macro_end): New functions.
(macro_build): Don't emit warnings here.
(macro_build_lui, md_estimate_size_before_relax): ...or here.
(md_convert_frag): Check for cases where one macro alternative
needs a warning and the other doesn't. Emit a warning if the
longer sequence was chosen.
* config/tc-mips.h (tc_frag_data_type, TC_FRAG_TYPE): Remove.
* config/tc-mips.c (RELAX_ENCODE): Take three arguments: the size of
the first sequence, the size of the second sequence, and a flag
that says whether we should warn.
(RELAX_OLD, RELAX_NEW, RELAX_RELOC[123]): Delete.
(RELAX_FIRST, RELAX_SECOND): New.
(mips_relax): New variable.
(relax_close_frag, relax_start, relax_switch, relax_end): New fns.
(append_insn): Remove "place" argument. Use mips_relax.sequence
rather than "place" to check whether we're expanding the second
alternative of a relaxable macro. Remove redundant check for
branch relaxation. If generating a normal insn, and there
is not enough room in the current frag, call relax_close_frag()
to close it. Update mips_relax.sizes[]. Emit fixups for the
second version of a relaxable macro. Record the first relaxable
fixup in mips_relax. Remove tc_gen_reloc workaround.
(macro_build): Remove all uses of "place". Use mips_relax.sequence
in the same way as in append_insn.
(mips16_macro_build): Remove "place" argument.
(macro_build_lui): As for macro_build. Don't drop the add_symbol
when generating the second version of a relaxable macro.
(load_got_offset, add_got_offset): New functions.
(load_address, macro): Use new relaxation machinery. Remove
tc_gen_reloc workarounds.
(md_estimate_size_before_relax): Set RELAX_USE_SECOND if the second
version of a relaxable macro is needed. Return -RELAX_SECOND if the
first version is needed.
(tc_gen_reloc): Remove relaxation handling.
(md_convert_frag): Go through the fixups for a relaxable macro and
mark those that belong to the unneeded alternative as done. If the
second alternative is needed, adjust the fixup addresses to account
for the deleted first alternative.
