[-- Attachment #1: Type: text/plain, Size: 614 bytes --]
This patch does not implement anything new, but simply separates OpenACC
'enter data' and 'exit data' into two libgomp API functions. The
original API name is kept for backward compatibility, but no longer
referenced by the compiler.
The previous implementation assumed that it would always be possible to
infer which kind of pragma it was dealing with from the context, but
there are a few exceptions, and I want to add one more: zero-length arrays.
By cleaning this up I will be free to add the new feature without the
reference counting getting broken.
OK for mainline (and backport to OG10)?

OpenACC: Separate enter/exit data APIs
Move the OpenACC enter and exit data directives from using a single builtin
to having one each. For most purposes it was easy to tell which was which,
from the directives given, but there are some exceptions. In particular,
zero-length array copies are indistiguishable, but we still want reference
counting to work.
gcc/ChangeLog:

Here's an updated patch that handles the variadic functions properly.
Thanks to Julian for pointing out my misunderstanding.
OK for mainline (and backport to OG10)?

OpenACC: Separate enter/exit data APIs
Move the OpenACC enter and exit data directives from using a single builtin
to having one each. For most purposes it was easy to tell which was which,
from the directives given, but there are some exceptions. In particular,
zero-length array copies are indistiguishable, but we still want reference
counting to work.

This update fixes a new conflict and updates the patterns in a number of
testcases that were affected.
OK to commit?

OpenACC: Separate enter/exit data APIs
Move the OpenACC enter and exit data directives from using a single builtin
to having one each. For most purposes it was easy to tell which was which,
from the directives given, but there are some exceptions. In particular,
zero-length array copies are indistiguishable, but we still want reference
counting to work.

ACK, that's a good cleanup already for its own sake.

... just that you missed all the Fortran testcases, had me do the "dirty

A few comments, hope that's useful:

We shall re-number, so that 'GF_OMP_TARGET_KIND_OACC_ENTER_DATA' and
'GF_OMP_TARGET_KIND_OACC_EXIT_DATA' stay in proximity.

As we've been told, new symbols need a new symbol version if 'GOACC_2.0'
(here) has already been part of a GCC release.

Don't remove: "This file contains prototypes of functions in the external
ABI" -- and 'GOACC_enter_exit_data' remains part of that.

The order 'async', 'data_enter', 'num_waits' seemed a bit awkward to me,
so I changed that to 'data_enter', 'async', 'num_waits'.

I've separately pushed "Clean up 'GOMP_MAP_POINTER' handling in

And, after separately pushed "Move
'libgomp/oacc-parallel.c:GOACC_declare' into 'libgomp/oacc-mem.c'", we
can then directly call the internal 'goacc_enter_exit_data_internal'
here, instead of the external 'GOACC_enter_data'/'GOACC_exit_data', which
is benefitial for certain reasons.

No reason to remove these as part of this patch.
Fixed these items, plus some minor additional clean-up.
I've then first pushed "Extract 'goacc_enter_exit_data_internal' from
'libgomp/oacc-mem.c:GOACC_enter_exit_data'" to master branch in
commit 7999363961dc6feeb0976cc6d85ea91a120d0e1d, see attached. Doing
that as a separate step makes sure that we don't break anything for
'GOACC_enter_exit_data'.
Then I've pushed "OpenACC: Separate enter/exit data ABIs" to master
branch in commit 7aefef31365b9c3d32a0edb6ea0d3b8864d7e91a, see attached.
This now doesn't anymore touch the old 'GOACC_enter_exit_data' ABI, so
cannot possibly break anything there.
Grüße
Thomas

Move the OpenACC enter and exit data directives from using a single builtin to
having one each. For most purposes it was easy to tell which was which, from
the clauses given, but it's overhead we can easily avoid, and there may be
future uses where that isn't possible.
