* doc/md.texi (extv@var{m}, extvmisalign@var{m}, extzv@var{m})
(extzvmisalign@var{m}, insv@var{m}, insvmisalign@var{m}): Document.
(insv, extv, extzv): Deprecate.
* optabs.def (insv_optab, extv_optab, extzv_optab)
(insvmisalign_optab, extvmisalign_optab, extzvmisalign_optab):
New optabs.
* optabs.c (get_optab_extraction_insn): New function.
(get_extraction_insn): Use it.
* config/mips/mips.md (extv): Split into...
(extvmisalign<mode>, extv<mode>): ...these new patterns. Rename
existing extv<mode> pattern to...
(*extv<mode>): ...this.
(extzv): Split into...
(extzvmisalign<mode>, extzv<mode>): ...these new patterns. Rename
existing extzv<mode> pattern to...
(*extzv<mode>): ...this.
(insv): Split into...
(insvmisalign<mode>, insv<mode>): ...these new patterns. Rename
existing insv<mode> pattern to...
(*insv<mode>): ...this. Use const_int_operand rather than
immediate_operand.
* config/mips/mips.c (mips_block_move_straight): Use set_mem_size
to set the size of BLKmode accesses.
(mips_get_unaligned_mem): Require OP0 to be a BLKmode memory,
turning it from an "rtx *" to an rtx.
(mips_expand_ext_as_unaligned_load): Simplify for new optab
interface. Update call to mips_get_unaligned_mem.
(mips_expand_ins_as_unaligned_store): Update call to
mips_get_unaligned_mem.
