Take the following C code:
-int x(int y) { return (y & 63) << 14; }
-
-Code produced by gcc:
- andl $63, %edi
- sall $14, %edi
- movl %edi, %eax
- ret
-
-Code produced by clang:
- shll $14, %edi
- movl %edi, %eax
- andl $1032192, %eax
- ret

-The code produced by gcc is 3 bytes shorter. This sort of construct often
-shows up with bitfields.

-Take the following C code:
int f(int a, int b) { return (unsigned char)a == (unsigned char)b; }
We generate the following IR with clang:
