For this it is convenient to permit floats to be used with EXTRACT_ELEMENT, so I tweaked things to allow that. I also added libcalls for ppcf128 to i32 forms of FP_TO_XINT, since they exist in libgcc and this case can certainly occur (and does occur in the testsuite) - before the i64 libcall was being used. Also, the XINT_TO_FP result seemed to be wrong when the argument is an i128: the wrong fudge factor was added (the i32 and i64 cases were handled directly, but the i128 code fell through to some generic softening code which seemed to think it was i64 to f32!). So I fixed it by adding a fudge factor that I found in my breakfast cereal. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52739 91177308-0d34-0410-b5e6-96231b3b80d8
