  • The -march flag has been added. The -misa + flag is now considered an alias of the -march flag.
    • +
  • Support for PTX ISA target architectures sm_53, + sm_70, sm_75 and sm_80 has been + added. These can be specified using the -march flag.
    • +
  • The default PTX ISA target architecture has been set back + to sm_30, to fix support for sm_30 boards.
    • +
  • The -march-map flag has been added. The + -march-map value will be mapped to an valid + -march flag value. For instance, + -march-map=sm_50 maps to -march=sm_35. + This can be used to specify that generated code is to be executed on a + board with at least some specific compute capability, without having to + know the valid values for the -march flag.
  • The -mptx flag has been added to specify the PTX ISA version for the generated code; permitted values are 3.1 - (default, matches previous GCC versions) and 6.3. + (matches previous GCC versions), 6.0, 6.3, + and 7.0. If not specified, the used version is the minimal + version required for -march but at least 6.0.
    • +
  • An mptx-3.1 multilib was added. This allows using older + drivers which do not support PTX ISA version 6.0.
  • The new __PTX_SM__ predefined macro allows code to check the - compute model being targeted by the compiler.
    • + PTX ISA target architecture being targeted by the compiler. +
  • The new __PTX_ISA_VERSION_MAJOR__ + and __PTX_ISA_VERSION_MINOR__ predefined macros allows code + to check the PTX ISA version being targeted by the compiler.
