[PATCH] D142234: [LVI] Handle Intrinsic::ctlz

[Antonio Frighetto via Phabricator via llvm-commits]

antoniofrighetto updated this revision to Diff 492056.
antoniofrighetto added a comment.

Moved the implementation in `ConstantRange.cpp`, and tested exhaustively. For the sake of completeness and rigor, I left the test in LVI, further improved: it shouldn’t harm, and there are similar unit tests in `ConstantRangeTest.cpp` which are also in test/Analysis.
