Dear GCC Team :
This is just a friendly letter. There probably will not be another GCC
update from the Sunfreeware site ( which is still showing 3.4.6 ) for a
long time now that Oracle has pulled finances. The same sad state of
affairs affects the OpenSolaris project as a whole.
I do expect that

Hello,
In the example accompanying the patch below we consider that the
types

at line marked with //#0 and

at the line marked with //#1 should compare equal. And I believe that
is correct[1].
It follows that during the instantiantion
Hi Sebastian,
I currently encountered an issue when testing
gcc.dg/graphite/interchange-9.c on a ARM bare-metal board which has only
4MB memory.
Apparently, with
#define N
#define M
"int A[N*M]" in main is too large to fit in stack.
There are several ways to solve this issue:
1.

This is the beta release of binutils 2.20.51.0.11 for Linux, which is
based on binutils 2010 0810 in CVS on sourceware.org plus various
changes. It is purely for Linux.
All relevant patches in patches have been applied to the source tree.

Are you trying to debug gcc or cc1/cc1plus? If the former try running
with -v and seeing that cc1/cc1plus is involved and then debug
cc1/cc1plus instead.
Thanks,

thanks so much. I was using gdb version 7.1. So it understood deferred
breakpoints but as long as I started gdb with something like ~/bin/gcc it never
stopped in my function.
As soon as I switched to running gdb on cc1, it worked!
Now i can work on debugging the seg-fault i'm causin
Hi Vladimir,
Thanks for the feedback! Very interesting.

That's a surprise to me. I have to say that the GCC community has done amazing
work, as you came within factor 1.4 (gfortran) and 1.6 (g++
