Subject: [RegisterBankInfo] Take advantage of the extra argument of SmallVector::resize.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=22bb41e797e148d070feec9f96a9f2db9ce1b58e;p=llvm

[RegisterBankInfo] Take advantage of the extra argument of SmallVector::resize.

When initializing an instance of OperandsMapper, instead of using
SmallVector::resize followed by std::fill, use the function that
directly does that in SmallVector.
