Sanjay Patel 9ac7e74796 [LibCallSimplifier] use instruction-level fast-math-flags to transform sqrt calls ... This is a continuation of adding FMF to call instructions: http://reviews.llvm.org/rL255555 The intent of the patch is to preserve the current behavior of the transform except that we use the sqrt instruction's 'fast' attribute as a trigger rather than the function-level attribute. But this raises a bug noted by the new FIXME comment. In order to do this transform: sqrt((x * x) * y) ---> fabs(x) * sqrt(y) ...we need all of the sqrt, the first fmul, and the second fmul to be 'fast'. If any of those ops is strict, we should bail out. Differential Revision: http://reviews.llvm.org/D15937 llvm-svn: 257400		2016-01-11 22:34:19 +00:00
