[LLVMdev] Using MSVC _ftol2 runtime function for fptoui on Win32
Hi Joe & Michael,
In rev. 151382 you have changed the fptoui implementation of the x86 codegen for win32.
Before the change fptoui was lowered to
flds 16(%esp)
fisttpll 8(%esp)
movl 8(%esp), %eax
After the change fptoui is lowered to
flds 40(%esp)
calll _ftol2
Please note that the assumption that _ftol2 doesn't modify ECX isn't true on sandybridge platform.
