Hi,
this patch makes the test-cases libgomp.oacc-c-c++-common/loop-g-{1,2}.c
work for non-nvidia devices.
For nvidia devices, a vector_length of 32 is required for the test to pass.
For devices with a non-32 forced vector_length, this test-case will fail
the test for excess errors due to:
...
warning: using vector_length (x), ignoring 32
...
Fixed by removing the explicit vector_length setting. For nvidia
devices, 32 is required, but that's also the forced default, so there's
no need to be explicit about it.
Committed as obvious.
Thanks,
- Tom
Fix libgomp.oacc-c-c++-common/loop-g-{1,2}.c for non-nvidia devices
2017-09-28 Tom de Vries <t...@codesourcery.com>
* testsuite/libgomp.oacc-c-c++-common/loop-g-1.c (main): Remove
vector_length(32) clause from acc parallel directive.
* testsuite/libgomp.oacc-c-c++-common/loop-g-2.c (main): Same.
