[Bug target/21715] [4.0/4.1 regression] code-generation performance regression

[kazu at gcc dot gnu dot org]

------- Comment #6 from kazu at gcc dot gnu dot org  2005-12-19 02:30 -------
I just compiled the testcase on x86_64.  I got

foo:
.LFB2:
        movq    %rdi, %rax
        negq    %rax
        andq    %rdi, %rax
        ret

which is as good as the assembly generated by 3.4.3.

This is no longer a regression on 4.2.
