This is probably an odd request, but I'd like to see more news
articles on GCC development. Every time a minor revision of the Linux
kernel comes out, there's no scarcity of news articles written about
it. Indeed, any time something interesting happens, someone writes an
article about it, like fo

Hi,
I am very sorry to insist but I would really appreciate if someone
could shed some light on my current problem. I really don't see why my
code is only segfaulting when using gcc4.0.1 (and above).
Description:
I am running a program that is outputing a file. The very same program

Actually, there's no guarantee that even if you submit patches to fix
a bug that it will be fixed in any official release.

Kevin, what you don't seem to understand is that the SC can't order
anyone to do anything. The SC has no employees, doesn't sign paychecks.

We noticed that the simple loop here
extern int a[];
int foo(int w) {
int n = w;
while (n >= 512)

}

Hi,
We're supposed to be getting closer to a 4.1 release branch, but just
like in the past so-many releases we have succeeded again in slowing
down GCC, and we've slowed it down a _lot_ compared even to GCC 4.0.
Taking SPECint and CSiBE as examples:

Please, stop screaming. We can hear you. This is the wrong list for
such questions. Please go try gcc-help.
I modified the file: ./libstdc++-v3/config/cpu/sparc/atomicity.h
to use the 32bit equivalent CAS/LD instructions from the arch64 bit in
the arch32.
I then built the code using the -mv8plus option in the (xxx)FLAGS and
all is happy.
However, the code will no longer compile without the v9 32bi
