  26         (mips_macro_warning): New variable.
  27         (md_assemble): Wrap macro expansion in macro_start() and macro_end().
  28         (s_cpload, s_cpsetup, s_cprestore, s_cpreturn): Likewise.
  29         (relax_close_frag): Set mips_macro_warning.first_frag.  Adjust use
  30         of RELAX_ENCODE.

  39 2004-01-23  Richard Sandiford  <rsandifo@redhat.com>
  40
  41         * config/tc-mips.h (tc_frag_data_type, TC_FRAG_TYPE): Remove.
  42         * config/tc-mips.c (RELAX_ENCODE): Take three arguments: the size of
  43         the first sequence, the size of the second sequence, and a flag
  44         that says whether we should warn.
  45         (RELAX_OLD, RELAX_NEW, RELAX_RELOC[123]): Delete.
  46         (RELAX_FIRST, RELAX_SECOND): New.

  48         (relax_close_frag, relax_start, relax_switch, relax_end): New fns.
  49         (append_insn): Remove "place" argument.  Use mips_relax.sequence
  50         rather than "place" to check whether we're expanding the second
  51         alternative of a relaxable macro.  Remove redundant check for
  52         branch relaxation.  If generating a normal insn, and there
  53         is not enough room in the current frag, call relax_close_frag()
  54         to close it.  Update mips_relax.sizes[].  Emit fixups for the
  55         second version of a relaxable macro.  Record the first relaxable
  56         fixup in mips_relax.  Remove tc_gen_reloc workaround.
  57         (macro_build): Remove all uses of "place".  Use mips_relax.sequence
  58         in the same way as in append_insn.
  59         (mips16_macro_build): Remove "place" argument.
  60         (macro_build_lui): As for macro_build.  Don't drop the add_symbol
  61         when generating the second version of a relaxable macro.
  62         (load_got_offset, add_got_offset): New functions.
  63         (load_address, macro): Use new relaxation machinery.  Remove
  64         tc_gen_reloc workarounds.
  65         (md_estimate_size_before_relax): Set RELAX_USE_SECOND if the second
  66         version of a relaxable macro is needed.  Return -RELAX_SECOND if the
  67         first version is needed.
  68         (tc_gen_reloc): Remove relaxation handling.
  69         (md_convert_frag): Go through the fixups for a relaxable macro and
  70         mark those that belong to the unneeded alternative as done.  If the
  71         second alternative is needed, adjust the fixup addresses to account
  72         for the deleted first alternative.
  73

  82         * config/tc-mips.c (append_insn): Don't do r3900 interlock
  83         optimization for -mtune=r3900, as this will break on other CPUs.
  84
  85 2004-01-11  Tom Rix   <tcrix@worldnet.att.net>
  86
  87         * config/tc-m68hc11.c (build_indexed_byte): movb and movw cannot
  88         be relaxed, use fixup.
  89         (md_apply_fix3): Use 5 bit reloc from movb and movw fixup.

  97
  98         * config/tc-mips.c (append_insn): Properly detect variant frags
  99         that preclude swapping of relaxed branches.  Correctly swap
