There may yet be changes made to this ABI, so it's # for testing only. # # rfscv is implemented to return from scv type system calls. It can not # be used to return from sc system calls because those are defined to # preserve lr. # # In a comparison of getpid syscall, the test program had scv taking # about 3 more cycles in user mode (92 vs 89 for sc), due to lr handling. # getpid syscall throughput on POWER9 is improved by 33%, mostly due to # reducing mtmsr and mtspr. # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-ld --version #
