Subject: Reset debug loc to OldInduction in InnerLoopVectorizer::createInductionVariable.... 
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=cc1ad89bbb4f0b720e0c07714109f628e6cb8106;p=llvm

Reset debug loc to OldInduction in InnerLoopVectorizer::createInductionVariable. (NFC)

This is to prevent SetInsertionPoint from setting debug loc to Latch->getTerminator().
