Subject: [committed][nvptx] Add -mptx=_
Date: Mon, 28 Feb 2022 10:16:04 +0100 [thread overview]
Message-ID: <20220228091603.GA5880@delia.home> (raw)
Hi,
Add an -mptx=_ value, that indicates the default ptx version.
It can be used to undo an explicit -mptx setting, so this:
...
$ gcc test.c -mptx=3.1 -mptx=_
...
has the same effect as:
...
$ gcc test.c
...
Tested on nvptx.
Committed to trunk.
Thanks,
- Tom
