>From 087e545747ca9ee977e84326877b0ce1bc4c383a Mon Sep 17 00:00:00 2001 From: Thomas Schwinge <tho...@codesourcery.com> Date: Fri, 21 Jan 2022 12:48:28 +0100 Subject: [PATCH] Strengthen a few OpenACC test cases Rather than rubber-stamp whatever requested vs. actual device kernel launch configuration happens, actually (again) verify the requested values (modulo expected variations). This better highlights that "AMD GCN has an upper limit of 'num_workers(16)'", and the deficiency that "AMD GCN uses the autovectorizer for the vector dimension: the use of a function call in vector-partitioned code [...] is not currently supported". And, this removes several instances of race conditions, where variables are concurrently written to in OpenACC gang-redundant mode. libgomp/ * testsuite/libgomp.oacc-c-c++-common/loop-gwv-1.c: Strengthen. * testsuite/libgomp.oacc-c-c++-common/loop-gwv-2.c: Likewise. * testsuite/libgomp.oacc-c-c++-common/loop-red-gwv-1.c: Likewise. * testsuite/libgomp.oacc-c-c++-common/loop-red-v-1.c: Likewise. * testsuite/libgomp.oacc-c-c++-common/loop-red-v-2.c: Likewise. * testsuite/libgomp.oacc-c-c++-common/loop-red-w-1.c: Likewise. * testsuite/libgomp.oacc-c-c++-common/loop-red-w-2.c: Likewise. * testsuite/libgomp.oacc-c-c++-common/loop-red-wv-1.c: Likewise. * testsuite/libgomp.oacc-c-c++-common/loop-v-1.c: Likewise. * testsuite/libgomp.oacc-c-c++-common/loop-w-1.c: Likewise. * testsuite/libgomp.oacc-c-c++-common/loop-wv-1.c: Likewise. * testsuite/libgomp.oacc-c-c++-common/routine-gwv-1.c: Likewise. * testsuite/libgomp.oacc-c-c++-common/routine-v-1.c: Likewise. * testsuite/libgomp.oacc-c-c++-common/routine-w-1.c: Likewise. * testsuite/libgomp.oacc-c-c++-common/routine-wv-1.c: Likewise. --- .../libgomp.oacc-c-c++-common/loop-gwv-1.c | 25 ++++++++++---- .../libgomp.oacc-c-c++-common/loop-gwv-2.c | 34 +++++++++++++++---- .../loop-red-gwv-1.c | 22 +++++++++--- .../libgomp.oacc-c-c++-common/loop-red-v-1.c | 11 ++++-- .../libgomp.oacc-c-c++-common/loop-red-v-2.c | 11 ++++-- .../libgomp.oacc-c-c++-common/loop-red-w-1.c | 13 +++++-- .../libgomp.oacc-c-c++-common/loop-red-w-2.c | 13 +++++-- .../libgomp.oacc-c-c++-common/loop-red-wv-1.c | 19 ++++++++--- .../libgomp.oacc-c-c++-common/loop-v-1.c | 13 +++++-- .../libgomp.oacc-c-c++-common/loop-w-1.c | 13 +++++-- .../libgomp.oacc-c-c++-common/loop-wv-1.c | 19 ++++++++--- .../libgomp.oacc-c-c++-common/routine-gwv-1.c | 21 +++++++++--- .../libgomp.oacc-c-c++-common/routine-v-1.c | 13 +++++-- .../libgomp.oacc-c-c++-common/routine-w-1.c | 13 +++++-- .../libgomp.oacc-c-c++-common/routine-wv-1.c | 19 ++++++++--- 15 files changed, 202 insertions(+), 57 deletions(-) diff --git a/libgomp/testsuite/libgomp.oacc-c-c++-common/loop-gwv-1.c b/libgomp/testsuite/libgomp.oacc-c-c++-common/loop-gwv-1.c index e5ed2ab7006..d3f6ea24e7e 100644 --- a/libgomp/testsuite/libgomp.oacc-c-c++-common/loop-gwv-1.c +++ b/libgomp/testsuite/libgomp.oacc-c-c++-common/loop-gwv-1.c @@ -19,9 +19,12 @@ int main () for (ix = 0;
