[nvptx] Add __PTX_ISA_VERSION_{MAJOR,MINOR}__
Add preprocessor macros __PTX_ISA_VERSION_MAJOR__ and
__PTX_ISA_VERSION_MINOR__.
For the default 6.0, we have:
...
$ echo | cc1 -E -dD - 2>&1 | grep PTX_ISA_VERSION
#define __PTX_ISA_VERSION_MAJOR__ 6
#define __PTX_ISA_VERSION_MINOR__ 0
...
and for 3.1, we have:
...
$ echo | cc1 -mptx=3.1 -E -dD - 2>&1 | grep PTX_ISA_VERSION
#define __PTX_ISA_VERSION_MAJOR__ 3
#define __PTX_ISA_VERSION_MINOR__ 1
...
These can be used to express things like:
...
#if __PTX_ISA_VERSION_MAJOR__ >= 4 && __PTX_ISA_VERSION_MAJOR__ >= 1
/* Code using %dynamic_smem_size. */
#else
/* Fallback code. */
#endif
...
Tested on nvptx.
