When I last attempted this patch I had the MINUS still in it but got
confused easily by needing to think of too many cases at once leading to
lots of stupid mistakes. Hence, I left it ou

This patch provides a workaround for unreliable operation of asynchronous
kernels regions on AMD GCN. At present, kernels regions are decomposed
into a series of parallel regions surrounded by a data region capturing
the data-movement clauses needed by the region as a whole:
#pragma acc kernels
These patches stabilise async support for AMD GCN. Several tests that
previously failed (some intermittently) now work.
Further commentary is provided alongside each patch. Tested with
offloading to AMD GCN.
I will apply shortly to the openacc-gcc-9-branch.
Thanks,
Julian

In libgomp, host-to-device transfers are instigated in several places
where the source data is either on the stack, or in an unstable
heap location (i.e. which is immediately freed after performing the
host-to-device transfer).
When the transfer is asynchronous, this means that taking the address
This patch lets the AMD GCN libgomp plugin wait for asynchronous queues
to have some space to push new operations when they are full, rather
than just erroring out immediately on that condition. This fixes the
libgomp.oacc-c-c++-common/da-4.c test.

Hi.
Here is a clean patch that does not fold roundeven resulting for
integer type and the conditions for folding functions
round/ceil/floor/roundeven and trunc only checks for signaling NaN.
This patch also conforms to GNU's coding style and standards. The fact
