Oh right! Something like a masked compare or so...probably not
implementable in an efficient way indeed I guess.
Whatever you call efficient. A simple memory compare won't do, as others
already pointed out, and everything else depends on the actual layout
of the structure.
Your structure is very short, code length will explode for larger
structures. It's inefficient compared to "REPE CMPSD" with proper
context, this is only a few lines.
andl $56, %eax
andl $56, %edx
cmpb %al, %dl
je .L49
.L42:
movl %esi, %eax
popl %edx
popl %ebx
popl %esi
ret
What does this part do btw? Compare lengths?
