Benjamin Kramer	44993ede60	[InstCombine] For cos/sin -> tan copy attributes from cos instead of the ... parent function Ideally we should merge the attributes from the functions somehow, but this is obviously an improvement over taking random attributes from the caller which will trip up the verifier if they're nonsensical for an unary intrinsic call. llvm-svn: 322284	2018-01-11 15:19:02 +00:00
Dmitry Venikov	e5fbf591a7	[InstCombine] Missed optimization in math expression: sin(x) / cos(x) => tan(x) ...
