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. gcc/ChangeLog: 2022-03-03 Tom de Vries * config/nvptx/t-nvptx (MULTILIB_EXTRA_OPTS): Add mptx=3.1. --- diff --git a/gcc/config/nvptx/t-nvptx b/gcc/config/nvptx/t-nvptx index 056d2dd..8f67264 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
