Hello,
the libgomp configuration for RTEMS uses currently the POSIX
implementation. Unfortunately the performance is unacceptable bad, so I
work currently on a specialized RTEMS configuration. I would like to
reuse the code of the Linux futex barrier. On RTEMS there is no
kernel/user space se

You can rewrite the RTL to make this easier. You can use a parallel to
do
Hi,
I have not been able to find an answer in the ".md" files i've read
through, or the docs, so I wanted to try here.
If we have an instruction on a machine that does "ADD x, y", where

For the following code
For(j = 0; j <= N;j++)
{
y = d[j];
For( I = 0 ; I <8 ; i++)
X(a[i]) = X(a[i]) + c[i] * y;
}

I think the issue here is dependences of X(A[i]) a
