masking shifts.
This fixes the miscompilation of this:
long long test1(unsigned A, unsigned B) {
return ((unsigned long long)A << 32) | B;
}
into this:
test1:
movl 4(%esp), %edx
movl %edx, %eax
orl 8(%esp), %eax
ret
allowing us to generate this instead:
test1:
movl 4(%esp), %edx
movl 8(%esp), %eax
ret
