Hi,
For following test-case, taken from pr88152.C:
#include
template
using V [[gnu::vector_size(N)]] = T;
int f10 (V a)
{
return _mm_movemask_pd (reinterpret_cast<__m128d> (a > __LONG_LONG_MAX__));
}
.optimized dump shows:
f10 (V a)
{
vector(2) signed long _1;
vector(2) long int _2;

You would need to change X th
Hi everyone,
I'll share my status for GSoC first evaluation.
Current status of libgomp task system:
I'll first summarize my understanding of libgomp.
Please correct me if I'm wrong.
Currently libgomp has 3 different queues: children_queue, taskloop_queue and
team_queue.
These three queues are pr
