4d7206a284 * config/tc-mips.h (tc_frag_data_type, TC_FRAG_TYPE): Remove.
* config/tc-mips.c (RELAX_ENCODE): Take three arguments: the size of

	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.

	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.

	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.
