Sparc has its own PTRACE_GETREGS64/PTRACE_SETREGS64 requests that transfer the uapi struct pt_regs directly from <asm/ptrace.h>, so thel ocal definition wasn't needed after all. One small quirk I hit though. The requests use the historical layout that omits %g0, so the transferred block starts at %g1 and every u_regs index is one lower than the register number suggests (%g1 is u_regs[0], %o0 is u_regs[7]). Will post v2 with a comment saying so now. Re-ran the suite on the T4-1 with the new version: still 95 of 95. -- Best regards Stian Halseth
