[nvptx] Add -mptx=_
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.
gcc/ChangeLog:
2022-02-28 Tom de Vries <tdevries@suse.de>
* config/nvptx/nvptx-opts.h (enum ptx_version): Add
PTX_VERSION_default.
* config/nvptx/nvptx.cc (handle_ptx_version_option): Handle
PTX_VERSION_default.
* config/nvptx/nvptx.opt: Add EnumValue "_" / PTX_VERSION_default.
