Tested by setting the default ptx isa version to 7.0, and doing a build and libgomp test run. gcc/ChangeLog: * config/nvptx/nvptx-opts.h (enum ptx_version): Add PTX_VERSION_7_0. * config/nvptx/nvptx.c (nvptx_file_start): Handle TARGET_PTX_7_0. * config/nvptx/nvptx.h (TARGET_PTX_7_0): New macro. * config/nvptx/nvptx.opt (ptx_version): Add 7.0.
