llvm-mirror/test/Transforms/InstSimplify/log-exp-intrinsic.ll
Sanjay Patel a4be43cc7e [InstSimplify] allow exp/log simplifications with only 'reassoc' FMF
These intrinsic folds were added with D41381, but only allowed with isFast().
That's more than necessary because FMF has 'reassoc' to apply to these
kinds of folds after D39304, and that's all we need in these cases.
