History

Sanjay Patel db811f479f [InstCombine] move tests for select with bit-test of condition; NFC These are all but 1 of the select-of-constant tests that appear to be transformed within foldSelectICmpAnd() and the block above it predicated by decomposeBitTestICmp(). As discussed in D45862 (and can be seen in several tests here), we probably want to stop doing those transforms because they can increase the instruction count without benefitting other passes or codegen. The 1 test not included here is a urem test where the bit hackery allows us to remove a urem. To preserve killing that urem, we should do some stronger known-bits analysis or pattern matching of 'urem x, (select-of-pow2-constants)'. llvm-svn: 330768		2018-04-24 21:06:06 +00:00
