wrong?
This issue concerned me, once lxvd2x is heavily used on compiled code.

It would be beneficial to make the behaviour consistent between those 2 cases.
Thanks for your input

Guys,
Small sample below fails (at least on 6.1) for multiple targets. The
difference between two functions start at the very first tree pass...
Please confirm that I'm not crazy and it's not supposed to be like this...

What the pitfalls or this approach are?
Thanks

Guys,
I'm trying to make compiler to generate better code on superscalar
in-order machine but can't find the right way to do it.
Imagine the following code:
long f(long* p, long a, long b)
{
long a1 = a << 2;
long a2 = a1 + b;
return p[a1] + p[a2];
}
by default compiler generates somethin

Or maybe permission denied? ;-)
Yeah, I can try to do benchmarking with such optset instead of O3.
Thanks,

Yeah, this is my point exactly. Atom case seems just triggered that fact.

Thanks a lot for the explanation!
I can take care of the benchmarking but only on Intel hardware... Do
you think that possble changes according those results would be
acceptable?

Hi All!
Is there any particular reason that matmul* modules from libgfortran
are compiled with -O2 -ftree-vectorize?
I see some regressions on Atom processor after r202980
(http://gcc.gnu.org/ml/gcc-cvs/2013-09/msg00846.html)
Why not just use O3 for those modules?
Thanks,
Igor

Thanks,

reaction on this PR I'd like to ask either
to look at it in some observable future or revert the commit which is
guilty for the issue.
Thanks,
Igor
anks a lot,

Hi All!
Is there any particular reason why tree loop if conversion
(tree-if-conv.c) isn't enabled by default on O2 (as far as I can see
it's true for any platforms)?
Thanks,
Igor
is problem?
Thanks in advance,

Hi All,
Sorry for my bad english.
How can I add to gcc support for a 8-bit micro (Harvard architecture)?
An RTFM link would be really appreciated. :-)
Thanks!

Consider the following code that starting with GCC 4.1.0 generates

grep the error messages.
Right, but are there any way to learn about endianess of the paltform
or the direction of stack growth just from knowing that program
compiles or not? GCC nows about this and it would be nice if there is
a way to expose these.
Regards, Igor
Is there any option to ask GCC to print various size and alignment
info on the target platform? This would be very nice during cross
compilation when one can not run the executables to autoconfigure for
such parameters.
Currently I consider for that a hack like copiling the following source:
