Subject: MIPS: asm: compiler: Add new macros to set ISA and arch asm annotations
From: Markos Chandras <markos.chandras@xxxxxxxxxx>
commit be5136988e25ae0dc8379fcb937efc63d87aba9e upstream.
There are certain places where the code uses .set mips32 or .set mips64
or .set arch=r4000. In preparation of MIPS R6 support, and in order to
use as less #ifdefs as possible, we define new macros to set similar
annotations for MIPS R6.
