2004-01-23  Richard Sandiford  <rsandifo@redhat.com>

	* 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.

2004-01-23  Richard Sandiford  <rsandifo@redhat.com>

	* 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.

2004-01-23  Richard Sandiford  <rsandifo@redhat.com>

	* frags.h (frag_room): Declare.
	* frags.c (frag_room): New function.
