Hi,
I have been exploring non-deterministic failures in cactusADM (when
autopar is enabled with a low threshold)' on a Power7 multi core machine.
The failure actually reoccurs in several other spec2006 benchmarks
when the threshold is lowered to allow for more loops to get parallelized.

Hello,
Described here is the future plan for automatic parallelization in GCC.
The current autopar pass is based on GOMP infrastructure; it distributes
iterations of loops
to several threads (the number is instructed by the user) if it was
determined that
they are independent. The only depen

Hi,
I'm trying to bootstrap with -ftree-parallelize-loops=4 enabled (passed as
BOOTCFLAGS).
I'm failing at the begining of stage2 because the compiler can't find
libgomp.spec
Can anyone help..?
Thanks,

Described these two optimizations in more detail.
O.K now?

In order to generate code for omp_atomic, I use force_gimple_operand which
calls gimplify_omp_atomic;
in some cases it calls gimplify_omp_atomic_pipeline, which expands the
atomic operation to a

However, the cond_expr that is

Hi,
My case is this:
I version the operator<< function and name it operator<<.number (creating
an identifier which is not valid in the source code).
The assembly name created for the versioned function is the same as the
tree identifier, which is not valid for the assembler.
I tried creating an
