This patch series fixes support for mixing arbitrary derived type
accesses and array element accesses in OpenACC directives, and fixes a
bug in derived-type lowering.
Somewhat relatedly, it also allows strided accesses in update directives.
Further commentary alongside each patch. Some of the test cases were
originally written by Tobias Burnus.
Tested with offloading to AMD GCN. OK for mainline (or for stage1)?
Thanks,
Julian
