Thanks for your great work.
This bug is mostly fixed, but one small detail remains. The final
jump back to the leave+ret sequence is still there.
Since leave+ret is a two-byte sequence, it makes sense to replace the
jump with a leave+ret.
Here is the -S -O2 output with gcc 3.3:
foo:
pushl %ebp
movl %esp, %ebp
subl $8, %esp
cmpb $0, 8(%ebp)
jle .L2
call a
.L3:
leave
ret
.p2align 2,,3
.L2:
call b
jmp .L3
The last jmp should become
leave
ret
