clang 3.2-1~exp5ubuntu2 on Ubuntu 13.04 amd64 gives a strange backend error
when compiling mosh (https://github.com/keithw/mosh). Using creduce I found
this minimal test case:
int main()
{
int n;
__builtin_expect(n, 0) && 0;
return 0;
}
fatal error: error in backend: Cannot select: 0x1be4580: i64 = fexp2 0x1be4480
[ORD=1] [ID=4]
0x1be4480: i64,ch = CopyFromReg 0x1bd1e30, 0x1be4380 [ORD=1] [ID=3]
0x1be4380: i64 = Register %vreg3 [ORD=1] [ID=1]
In function: main
