gcc asm bug for shifts and rotates

Not sure if this is the correct forum for bug reports on gcc, but here
goes anyway. Opcodes such as

sal %cl,20(%esp)

need a size specifier to say whether the 20(%esp) is a byte, half word
or word pointer. For most opcodes requiring a size specifier, gcc
complains if it is missing. But for this one, and probably other
shifts and rotates, it just silently chooses byte.
