[LLVMdev] X86 rsqrt instruction generated
Hi, We have implemented the rsqrt instruction generation for X86 target architecture. We have introduced a flag -fp-rsqrt flag which controls the generatation of X86 rsqrt instruction generation. We have observed minor effects on precision due to rsqrt and hence has put these transformations under the mentioned flag. Note that -fp-rsqrt is only enabled with -enable-unsafe-fp-math flag presently.
