* config/tc-mips.h (tc_frag_data_type, TC_FRAG_TYPE): Remove.

Browse source 
* 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.

	* gas/mips/elf-rel19.[sd]: New test.
