[Bug target/27440] [4.0/4.1/4.2 regression] code quality regression due to ivopts

[rguenth at gcc dot gnu dot org]

------- Comment #6 from rguenth at gcc dot gnu dot org  2006-10-10 14:06 -------
Confirmed (as in comment #1).  With -Os instead of -O2 we even produce

.L3:
        movl    %ebx, -4(%edx)
        incl    %eax
.L2:
        addl    $4, %edx
        cmpl    %ecx, %eax
        jb      .L3

(because loop header copying is disabled there).
