Subject: [TargetLowering] SimplifyDemandedVectorElts - use same arg names as SimplifyDemandedB... 
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=e1e70d12644bce83a071ec4e387237272e91bc28;p=llvm

[TargetLowering] SimplifyDemandedVectorElts - use same arg names as SimplifyDemandedBits. NFCI.

Helps with debugging as we recurse between them.
