Hi, In gcc-5 to gcc-11, the ptx isa version was 3.1.
On trunk, the default is now 6.0, which is also what will be the value in the libraries. Consequently, there may be setups with an older driver that worked with gcc-11, but will become unsupported with gcc-12. Fix this by building the libraries with mptx=3.1. After this, setups with an older driver still won't work out of the box with gcc-12, because the default ptx isa version has changed, but should work after specifying mptx=3.1. Committed to trunk. Thanks, - Tom [nvptx] Build libraries with mptx=3.1 gcc/ChangeLog: 2022-03-03 Tom de Vries <tdevr...@suse.de> * config/nvptx/t-nvptx (MULTILIB_EXTRA_OPTS): Add mptx=3.1. --- gcc/config/nvptx/t-nvptx | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/gcc/config/nvptx/t-nvptx b/gcc/config/nvptx/t-nvptx index 056d2dd2d04..8f67264d132 100644 --- a/gcc/config/nvptx/t-nvptx +++ b/gcc/config/nvptx/t-nvptx @@ -32,4 +32,4 @@ s-nvptx-gen-opt: $(srcdir)/config/nvptx/nvptx-sm.def MULTILIB_OPTIONS = mgomp -MULTILIB_EXTRA_OPTS = misa=sm_30 +MULTILIB_EXTRA_OPTS = misa=sm_30 mptx=3.1
