This patch adds a new function to logically decrement the "dynamic
reference counter" for a mapped OpenACC variable, and handles some cases
in which that counter drops to zero inside a structured data
block. Previously, it's likely that at least in some cases, ending a
dynamic data lifetime in
es. Tested with
offloading to NVPTX, also with a version of my refcount-verification patch
(not currently on trunk).
I believe this (at least the first two parts) fixes a regression (for
the pr92843-1.c test case), so OK for stage 4?
Thanks,
Julian
Julian Brown (3):
Introduce dynamic data mappin
This patch prevents "exit data" directives from copying back data that
was mapped with an acc_map_data API call. This matches the behaviour
expected by the pr92843-1.c test, and together with the previous patch
in this series, allows that test to pass (with no other regressions).

This patch provides a way to distinguish target_mem_descs that arise from
"enter data" operations from those that arise from structured OpenACC
data blocks. In that way, we can implement the equivalent of the "no-op"
behaviour of decrementing a dynamic reference count that is already zero

It appears that the hsa_memory_copy API routine
has problems copying from read-only data: in the
libgomp/testsuite/libgomp.oacc-c-c++-common/reduction-8.c test, a "const"
variable cannot be successfully copied to the target. I think the problem
is with read-only page mappings (in the HSA runtime).
The AMD GCN runtime support appears to exercise asynchronous operations
more heavily than other offload targets. As such, latent problems with
asynchronous host-to-device copies have come to light with GCN. This
patch provides a solution to those.

that support.
Tested with offloading to NVPTX, with good results (though a couple of
tests need fixing also).
A follow-up patch provides self-checking of the reference count
implementation.
OK for trunk?
Thanks,
Julian

This patch adds profiling support to the AMD GCN libgomp plugin, modeled
after the equivalent support in the NVPTX plugin. This gives a positive
test delta in AMD GCN offload testing.
I will apply to the openacc-gcc-9-branch shortly.
