Bug #: 14707
Summary: fptoui crash
Product: libraries
Version: trunk
Platform: PC
OS/Version: Windows XP

sample code
The attached LLVM assembly file causes lli to crash on Windows XP 32 bits.
The function
define internal i32 @Addr_002CB450(double) {
%retvalue = fptoui double %0 to i32
ret i32 %retvalue
}
is being translated to
_Addr_002CB450: # @Addr_002CB450
# BB#0:
pushl %ebp
movl %esp, %ebp
andl $-8, %esp
subl $16, %esp
movsd 8(%ebp), %xmm0
movsd %xmm0, 8(%esp)
fldl 8(%esp)
calll __ftol2
movl %ebp, %esp
popl %ebp
ret
(note the call to __ftol2, so there is a integer size mismatch)
