--- Comment #2 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Tom de Vries <vr...@gcc.gnu.org>: https://gcc.gnu.org/g:a2eacdbd4c4a698b3b6f27ef5e1f8dd3d836b2e5 commit r12-7893-ga2eacdbd4c4a698b3b6f27ef5e1f8dd3d836b2e5 Author: Tom de Vries <tdevr...@suse.de> Date: Tue Mar 29 16:04:09 2022 +0200 [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 ...
