[PATCH] D149587: InstSimplify: Simplifications for ldexp

[Jay Foad via Phabricator via llvm-commits]

foad added a comment.

I think you can simplify ldexp(x, C) -> x * ldexp(1.0, C). Even for strictfp this should work if you use a constrained fmul and the if the new ldexp itself does not overflow or underflow.
