Try and compile a conftest that uses it. If you wanted a possibly

Snapshot gcc-4.5-20120119 is now available on
ftp://gcc.gnu.org/pub/gcc/snapshots/4.5-20120119/
and on various mirrors, see http://gcc.gnu.org/mirrors.html for details.
This snapshot has been generated from the GCC 4.5 SVN branch

For a Go program being compiled in gcc, from the middle end, is there a way to
figure-out which routines make up the interface-method-table? I could check the

methods compose it from the middle-end?
Thanks!

Nice work! The only think is that you didn't enable WPO/LTCG on VC++
builds, so that test is a little skewed...

Write a test that checks for the existence of that machinery. I agree with the
earlier comments. Checking version strings or program names is the wrong way,
because you're essentially saying "if it is X then I know it can do Y" rather
than directly asking the question "can it do Y". The issue
libacml from AMD is also a good candidate to try:

Hi Ludo,
A number of compilers claim to be GCC, without actually being GCC. This
has come to a point where they can hardly be distinguished–until one
actually tries to use them.
this suggests that you shouldn't be testing for GCC, and instead should be
testing for support for particular featu

Does the vectorizer fail on unrolled loops?
I can compile some assembly dumps showing both the vectorized and the
unvectorized loop?

Hello.
Thanks for your fast response.
With expand_location I get struct expanded_location which has these fields:

I know how I have to use expand_location function but I
