Remove the 3 HACK HACK HACKs I put in before, fixing them properly with
...
the new TLI that is available.
Implement support for handling out of range shifts. This allows us to
compile this code (a 64-bit rotate):
unsigned long long f3(unsigned long long x) {
return (x << 32) | (x >> (64-32));
}
into this:
f3:
mov %EDX, DWORD PTR [%ESP + 4]
mov %EAX, DWORD PTR [%ESP + 8]
ret
GCC produces this:
$ gcc t.c -masm=intel -O3 -S -o - -fomit-frame-pointer
..
f3:
push %ebx
mov %ebx, DWORD PTR [%esp+12]
mov %ecx, DWORD PTR [%esp+8]
mov %eax, %ebx
mov %edx, %ecx
pop %ebx
ret
The Simple ISEL produces (eww gross):
f3:
sub %ESP, 4
mov DWORD PTR [%ESP], %ESI
mov %EDX, DWORD PTR [%ESP + 8]
mov %ECX, DWORD PTR [%ESP + 12]
mov %EAX, 0
mov %ESI, 0
or %EAX, %ECX
or %EDX, %ESI
mov %ESI, DWORD PTR [%ESP]
add %ESP, 4
