Richard,
I apologize for the mix up in testing the race
condition patch for value profiling of the indirect
calls on darwin. We may need to regress that out for
gcc 4.5, but first I would like to try to get a PR
opened to define the scope of the problem that it causes.
In particular, it is very

for gcov_indirect, I get

Hi,
I would like to add swap32 built in function to gcc. I looked how other
built in functions are implemented, but I didn't managed.
Can someone give me some idea what to do?

Hi,
The old GNU assemblers may use memcpy to copy overlap memory:
http://sourceware.org/bugzilla/show_bug.cgi?id=11456
It has been fixed by replacing memcpy with memove. I recommend
all existing GNU assemblers be fixed, especially with glibc trunk on
x86 since it has the optimized memcpy which m

If you mean something like __builtin_bswap32, just use it ;)

If you mean something else... explain in better detail.

The problem (again) is that floating point multiplication is
just too damn fast. On x86, even though the latency

Hi, I'm new in mail list, I expect that it is the right place to ask
for guidance.
I want to track input variables between functions. I already can mark
and track an input variable in the same function; however, when the
program uses that variable (directly or indirectly) as a argument in a

Hello,
The mercurial mirror of the gcc repository, at http://gcc.gnu.org/hg/gcc has
been broken for months. and the contact listed there does not answer emails.
Can somebody here at least remove those misleading pages..?
Also, i would volunteer to fix this, and even to maintain the mirror.
