Greetings,
I have a patch in my tree that employs the constexpr keyword in most of
the places in the library where it is required in n3000. This patch
bootstraps and causes no new regressions on MacOS at least. I still
need test cases.
My question is this: Is constexpr in good enough shape

Above gcc/config/ia64/ia64.c:ia64_print_operand.

Greetings,
A pointer would be much appreciated!
In ia64.md for *cmpdi_normal this is found:
"cmp.%C1 %0, %I0 = %3, %r2"
Where are %C, %I, %r described?

Thanks Tim, I thought that the gcc list was the most appropriate one
regarding the gomp implementation, but I'll post this question on the
gcc-help list.
By the way, Ubuntu 9.10 is the latest version (dd Oct. 2009). HTT works
fine for daily use, but massive parallel applications show some odd

If you think a question might be related to gcc, but don't know which
forum to use, gcc-help is more
Dear gcc list,
I noticed that starting an OpenMP parallel section takes a significant
amount of time on Nehalem cpu's with hyper-threading enabled.
The differences with HTT turned on and off are really huge:
- HTT disabled: about 100.000 parallel sections per second
- HTT enabled: about 15 pa
