Hi, Before the commit "[libgomp, testsuite, openacc] Don't use const int for dimensions", the "const int" construct was used to set launch dimensions in reductions-[1-5].c. In the case of -xc -O0, the const int is implemented as a variable by the C front-end. Consequently, the nvptx back-end generated warnings that vector_length was overridden to be hard-coded, rather than left to be set at runtime. The test-cases silenced these warnings by switching off all warnings in the accelerator compiler using "-foffload=-w".
Given that no warnings occur anymore, remove the "-foffload=-w" setting. Committed to trunk. Thanks, - Tom [libgomp, testsuite, openacc] Remove -foffload=-w in reduction-[1-5].c 2019-01-11 Tom de Vries <tdevr...@suse.de> * testsuite/libgomp.oacc-c-c++-common/reduction-1.c: Remove -foffload=-w. * testsuite/libgomp.oacc-c-c++-common/reduction-2.c: Same. * testsuite/libgomp.oacc-c-c++-common/reduction-3.c: Same. * testsuite/libgomp.oacc-c-c++-common/reduction-4.c: Same. * testsuite/libgomp.oacc-c-c++-common/reduction-5.c: Same. --- libgomp/testsuite/libgomp.oacc-c-c++-common/reduction-1.c | 3 --- libgomp/testsuite/libgomp.oacc-c-c++-common/reduction-2.c | 3 --- libgomp/testsuite/libgomp.oacc-c-c++-common/reduction-3.c | 3 --- libgomp/testsuite/libgomp.oacc-c-c++-common/reduction-4.c | 3 --- libgomp/testsuite/libgomp.oacc-c-c++-common/reduction-5.c | 3 --- 5 files changed, 15 deletions(-) diff --git a/libgomp/testsuite/libgomp.oacc-c-c++-common/reduction-1.c b/libgomp/testsuite/libgomp.oacc-c-c++-common/reduction-1.c index 3fe9ae65309..4e76ccd5b5c 100644 --- a/libgomp/testsuite/libgomp.oacc-c-c++-common/reduction-1.c +++ b/libgomp/testsuite/libgomp.oacc-c-c++-common/reduction-1.c @@ -1,8 +1,5 @@ /* { dg-do run } */ -/* Ignore vector_length warnings for offloaded (nvptx) targets. */ -/* { dg-additional-options "-foffload=-w" } */ - /* Integer reductions. */ #include <stdlib.h> diff --git a/libgomp/testsuite/libgomp.oacc-c-c++-common/reduction-2.c b/libgomp/testsuite/libgomp.oacc-c-c++-common/reduction-2.c index 83986abf7e0..96e6c079ef3 100644 --- a/libgomp/testsuite/libgomp.oacc-c-c++-common/reduction-2.c +++ b/libgomp/testsuite/libgomp.oacc-c-c++-common/reduction-2.c @@ -1,8 +1,5 @@ /* { dg-do run } */ -/* Ignore vector_length warnings for offloaded (nvptx) targets. */ -/* { dg-additional-options "-foffload=-w" } */ - /* float reductions. */ #include <stdlib.h> diff --git a/libgomp/testsuite/libgomp.oacc-c-c++-common/reduction-3.c b/libgomp/testsuite/libgomp.oacc-c-c++-common/reduction-3.c index 3ac0f996a86..dc18426d748 100644 --- a/libgomp/testsuite/libgomp.oacc-c-c++-common/reduction-3.c +++ b/libgomp/testsuite/libgomp.oacc-c-c++-common/reduction-3.c @@ -1,8 +1,5 @@ /* { dg-do run } */ -/* Ignore vector_length warnings for offloaded (nvptx) targets. */ -/* { dg-additional-options "-foffload=-w" } */ - /* double reductions. */ #include <stdlib.h> diff --git a/libgomp/testsuite/libgomp.oacc-c-c++-common/reduction-4.c b/libgomp/testsuite/libgomp.oacc-c-c++-common/reduction-4.c index b8fa954cfee..d152674be45 100644 --- a/libgomp/testsuite/libgomp.oacc-c-c++-common/reduction-4.c +++ b/libgomp/testsuite/libgomp.oacc-c-c++-common/reduction-4.c @@ -1,8 +1,5 @@ /* { dg-do run { target { ! { hppa*-*-hpux* } } } } */ -/* Ignore vector_length warnings for offloaded (nvptx) targets. */ -/* { dg-additional-options "-foffload=-w" } */ - /* complex reductions. */ #include <stdlib.h> diff --git a/libgomp/testsuite/libgomp.oacc-c-c++-common/reduction-5.c b/libgomp/testsuite/libgomp.oacc-c-c++-common/reduction-5.c index 215d919a103..6f5d29316a0 100644 --- a/libgomp/testsuite/libgomp.oacc-c-c++-common/reduction-5.c +++ b/libgomp/testsuite/libgomp.oacc-c-c++-common/reduction-5.c @@ -1,9 +1,6 @@ /* { dg-do run } */ /* { dg-additional-options "-w" } */ -/* Ignore vector_length warnings for offloaded (nvptx) targets. */ -/* { dg-additional-options "-foffload=-w" } */ - /* Multiple reductions. */ #include <stdio.h>
