Subject: mips.md (cprestore): Provide two alternatives...
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b8b044f117805342a401401483c7d62f8a62cc59;p=gcc.git

mips.md (cprestore): Provide two alternatives...

	* config/mips/mips.md (cprestore): Provide two alternatives, one for
	an in-range offset and one for an out-of-range offset.  Wrap the latter
	in .set macro/.set nomacro if it's inside a .set nomacro block.
