46 (RELAX_FIRST, RELAX_SECOND): Turn into 8-bit quantities.

49 (mips_macro_warning): New variable.

53 of RELAX_ENCODE.

63
64 * config/tc-mips.h (tc_frag_data_type, TC_FRAG_TYPE): Remove.
65 * config/tc-mips.c (RELAX_ENCODE): Take three arguments: the size of
66 the first sequence, the size of the second sequence, and a flag
67 that says whether we should warn.
68 (RELAX_OLD, RELAX_NEW, RELAX_RELOC[123]): Delete.
69 (RELAX_FIRST, RELAX_SECOND): New.
70 (mips_relax): New variable.
71 (relax_close_frag, relax_start, relax_switch, relax_end): New fns.
72 (append_insn): Remove "place" argument. Use mips_relax.sequence
73 rather than "place" to check whether we're expanding the second
74 alternative of a relaxable macro. Remove redundant check for
75 branch relaxation. If generating a normal insn, and there
76 is not enough room in the current frag, call relax_close_frag()
77 to close it. Update mips_relax.sizes[]. Emit fixups for the
78 second version of a relaxable macro. Record the first relaxable
79 fixup in mips_relax. Remove tc_gen_reloc workaround.
80 (macro_build): Remove all uses of "place". Use mips_relax.sequence
81 in the same way as in append_insn.
82 (mips16_macro_build): Remove "place" argument.
83 (macro_build_lui): As for macro_build. Don't drop the add_symbol
84 when generating the second version of a relaxable macro.
85 (load_got_offset, add_got_offset): New functions.
86 (load_address, macro): Use new relaxation machinery. Remove
87 tc_gen_reloc workarounds.
88 (md_estimate_size_before_relax): Set RELAX_USE_SECOND if the second
89 version of a relaxable macro is needed. Return -RELAX_SECOND if the
90 first version is needed.
91 (tc_gen_reloc): Remove relaxation handling.
92 (md_convert_frag): Go through the fixups for a relaxable macro and
93 mark those that belong to the unneeded alternative as done. If the
94 second alternative is needed, adjust the fixup addresses to account
95 for the deleted first alternative.

121 * config/tc-mips.c (append_insn): Properly detect variant frags
122 that preclude swapping of relaxed branches. Correctly swap
123 instructions between frags when dealing with relaxed branches.
