llvm-mirror/test/Transforms/BBVectorize/func-alias.ll
Hal Finkel 56c6162a55 Update BBVectorize to use aliasesUnknownInst.
This allows BBVectorize to check the "unknown instruction" list in the
alias sets. This is important to prevent instruction fusing from reordering
function calls. Resolves PR11920.
