Date: Wed, 4 Nov 2020 18:28:21 +0100 [thread overview]
Message-ID: <e34c6440-b577-1ee7-aa00-5826f5f536f4@linux.ibm.com> (raw)
In-Reply-To: <20201103214656.1877781-1-iii@linux.ibm.com>
These tests all use the -mzvector option but do not appear to make use of the z vector languages
extensions. I think that option could be removed. Then these tests should be moved to the vector subdir.
You could do the asm scanning also in dg-do run tests.
