||
|
||
* config/tc-mips.c (load_address, macro): Update comments about
|
||
NewABI GP relaxation.

||
(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.

|
||
(s_cpload, s_cpsetup, s_cprestore, s_cpreturn): Likewise.

|
||
* config/tc-mips.c (RELAX_ENCODE): Take three arguments: the size of

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.

|
||
|
||
* config/tc-mips.c (append_insn): Properly detect variant frags
|
||
