I've been working on it. Is there a PR?

Hi,
I have a fairly decent knowledge about compiler internals, object
oriented programming and algorithms. I would like to make a
non-trivial contribution to gcc/g++. I am interested in adding a new
optimization phase or improving some existing ones or write stuff
related to OO program compilati

Jakub,
Have you made any progress on fixing this? I would rather that the
debug information is not available than that equivalence is broken.
Best regards

I modified the gcc i386 backend. Now my gcc optimizes function prologue

movq%rbp, -8(%rsp)
subq$16, %rsp
to
movq%rbx, -16(%rsp)
movq%rbp, -8(%rsp)
pushq %rax
pushq %rax
The change was introduced b

Once you've checked out a tree, CVS stores the remote user in the

What's the magic incantation to get gcc with subversion?
I've read the wiki page, but
troutmask:sgk[205] svn co svn+ssh://gcc.gnu.org/svn/gcc/trunk
Permission denied (publickey,gssapi-with-mic).

I would not recommend use of uberbaum. There are some old-time

The advice you'll get here is exactly the same: post a small example
which reproduces the error message which troubles you.

Hi Dave,
Thanks for that patch. It has taken me a while to get around to using
it, but it is very useful. I've attached a version which works with the
current mainline.
Was there any particular reason why you haven't submitted it to
mainline, as I'm sure that others could benefit from it?

int main(void) {
const char * const literal = "xxx";
fprintf(stderr, literal);
return 0;
}

Hi,
Since October 13, SPEC's swim, applu, and sixtrack fail to build and

I am working on a VC++ to gcc conversion, and I'm facing some problems that
I cannot find the answers for. I'm working on a Windows XP machine with
