X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=955cd057454b323419e06affa7df7d59dc3cd1fb;p=gcc.git

Add gcc/config/gcn/t-omp-device for OpenMP declare variant kind/arch/isa

        gcc/
        * config/gcn/gcn.c (gcn_omp_device_kind_arch_isa): New function.
        (TARGET_OMP_DEVICE_KIND_ARCH_ISA): Redefine to
        gcn_omp_device_kind_arch_isa.
        * config/gcn/t-omp-device: New file.
        * configure.ac: Support gcn for omp_device_property.
        * configure: Regenerate.
