- Subject: inefficient code output?
is there a reason for code output like the following or is this a bug?
if it is I can try to provide a simple example.
movl %ebx, -200(%ebp)
movl %ebx, -196(%ebp)
movl %eax, 4(%esp)
movl -200(%ebp), %edx
movl -196(%ebp), %ecx
gcc 3.4.3, -O3 -march=pentium4 -mtune=pentium4 -mfpmatch=sse -msse2
no "volatile" involved.
