X-Git-Tag: upstream/17.0.6~21426
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=43cf2f8103f9ef0f292c2cd12e89c55406182e1a;p=platform%2Fupstream%2Fllvm.git

[LoongArch] Refine the condition to return Match_RequiresAMORdDifferRkRj in AsmParser. NFC

This can suppress compilation warning like `enumerated mismatch in conditional expression`.
