Subject: SimplifySelectOps can only handle selects with a scalar condition. Add a check
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=f94fdb6f571c2cdf8390ead558ba40b267df1172;p=llvm

SimplifySelectOps can only handle selects with a scalar condition. Add a check
that the condition is not a vector.
