[llvm-commits] CVS: llvm/lib/Target/X86/X86ISelLowering.cpp

[Evan Cheng]

Changes in directory llvm/lib/Target/X86:

X86ISelLowering.cpp updated: 1.45 -> 1.46
---
Log message:

SSE does not support i64 SINT_TO_FP (FP stack doesn't either, but we custom
expand it), so ask legalizer to expand i32 UINT_TO_FP.
