Ulrich Weigand 6c28a7eec8 This patch fixes failures in the SingleSource/Regression/C/uint64_to_float test case on PowerPC caused by rounding errors when converting from a 64-bit integer to a single-precision floating point. The reason for this are double-rounding effects, since on PowerPC we have to convert to an intermediate double-precision value first, which gets rounded to the final single-precision result. The patch fixes the problem by preparing the 64-bit integer so that the first conversion step to double-precision will always be exact, and the final rounding step will result in the correctly-rounded single-precision result. The generated code sequence is equivalent to what GCC would generate. When -enable-unsafe-fp-math is in effect, that extra effort is omitted and we accept possible rounding errors (just like GCC does as well). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166178 91177308-0d34-0410-b5e6-96231b3b80d8		2012-10-18 13:16:11 +00:00
