------- Comment #7 from bagnara at cs dot unipr dot it 2005-12-20 07:49 -------
I can confirm both problems (incorrect reordering and performance regression)
are present in GCC version 4.0.2 and version 4.2.0 20051209 (experimental).

Confirmed, we should not be reordering unary minus with -frounding-math but we
are, even on the mainline.

It's convert.c:convert_to_real which does this. Should be easy to fix.

Unless I'm mistaken, the patch has only been applied to the trunk and not to
the branches, in particular not to the current release series. Shouldn't this
bug-report, either be reopened until it has been fixed in all active branches,
or be closed as "won't fix"?

As this isn't a regression from previous releases the policy is to fix such
bugs in current development sources only and declare it as fixed there.
With wrong-code bugs we sometimes make exceptions, but the release manager has
to approve this. So you can raise this particular issue on the mailinglist and
CC

Actually, not only is it wrong-code, but this is also a regression (see
PR29538). Programs using interval arithmetic that were working fine when
compiled with GCC 3.3 are broken now.

My fault: I forgot to use the -frounding-math option. So, for the "wrong-code"
aspect there is no problem. But the "missed-optimization" bit is still there:
why do we have
fldl 12(%ebp)
fchs
movl 8(%ebp), %eax
fstps -20(%ebp)
flds -20(%ebp)
fstps -4(%ebp)
flds -4(%ebp)
fchs
fstps (%eax)
insted of simply
fldl 12(%ebp)
fchs
fstps -4(%ebp)
flds -4(%ebp)
fchs
fstps (%eax)
?

Since the original issue is resolved and the audit trail of the bug already
very long, I'll close this PR. If you feel that the missed optimization
isn't addressed yet, please open a new report with this issue that solely
tracks the optimization enhancement request.
