I really think a modern Linux port should support those > (and only those), but Linux/M32R isn't going to support them, the code > can be simplified even more. It sounds reasonable. I'll implement PTRACE_GETREGS/PTRACE_SETREGS on Linux/M32R kernel and simplify the register handling codes. > Are there any plans to support a FPU? Some chips of M32R have FPU. But their target is ECU (Engine Control Unit) and does not support Linux because ECU doesn't need a large OS like Linux. So FPU support is not necessary for Linux/M32R. > Meanwhile I have a few more comments concerning m32r-linux-tdep.c. OK. I'll revise my patch. === Kei Sakamoto Renesas Technology Corp. sakamoto.kei@renesas.com
