The majority of the time spent in the pass checking for the register reads. Rather than searching all of the defined registers for uses in each instruction, use a set of defined registers and check the operands of the instruction. This process still is algorithmically not great, but with the additional trick of skipping the analysis for addresses with one use, this brings one slow testcase into a reasonable range. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@312206 91177308-0d34-0410-b5e6-96231b3b80d8
