the failures I got in the Ada testsuite were:

Patch that fixes the problem and does not introduce regressions
The previous patch had a few regressions in vlas,
The problem occurs with both 3.4.5 and 3.4.6. I haven't tested newer compilers,
but 3.3.6 works. Problem can be avoided by reducing -O2 to -O1.

We're moved on since then and haven't been able to verify the fix. I
would say close it if the related bug has been fixed.

Hi guys. My name is Clint Whaley, I'm the developer of ATLAS, an open source
linear algebra package:

My users are asking me to support gcc 4, but right now its x87 fp performance
is much worse than gcc 3. Depending on the machine and code being run it

Do you have a small testcase which shows the problem?

Andrew,
Thanks for the reply. For the small case demonstrating the problem, I

Yes, I agree it is an x86/x86_64 issue. I have not yet scoped the performance
of any of the other architectures with gcc 4 vs. 3: since 90% of

Andrew,
I can confirm that the proposed patch (with the missing null check) resolves
the new gfortran
failures on Darwin. Could you update the patch in this PR to revised version
with the null check
Calling an ARM-targeted GCC 3.4.4 on the testsuite file gcc.dg/pr21255-2-mb.c
results in internal compiler error: in shift_op, at config/arm/arm.c:7917.
A slightly reduced version of the file is:
double d;

f (void)
{
double r;
asm (mov %S1,%S0; mov %R1,%R0 : =r (r) : m (d));

Does this happen in 3.4.5 or 3.4.6?
Also 3.4.x is no longer being maintainer, does this happen in 4.0.x or 4.1.x?
