2019-07-16[mips] Fix ambiguous .md attribute usesRichard Sandiford1-1/+1
This patch is part of a series that fixes ambiguous attribute uses in .md files, i.e. cases in which attributes didn't use <ITER:ATTR> to specify an iterator, and in which <ATTR> could have different values depending on the iterator chosen. No behavioural change -- produces the same code as before. 2019-07-16 Richard Sandiford <richard.sandiford@arm.com> gcc/ * config/mips/micromips.md (*movep<MOVEP1:mode><MOVEP2:mode>): Explicitly use <MOVEP1:MODE> for the mode attribute.
