Package: gcc-3.0
Version: 1:3.0-0pre010403
Severity: minor
gcc-3.0 wastes a byte in the following code on i386:
a:
pushl %ebp
movl %esp, %ebp
movl 8(%ebp), %eax
andl $1, %eax
cwtl
popl %ebp
ret
The cwtl is unnecessary since %eax has just been anded with 1.
The source is:
int a(short i) {
return i & 1;
}
