--000e0cd11bb4a9c925047ea9800a Content-Type: text/plain; charset=UTF-8 The ptrace system call implementation seems to have a bug, we need to save ra and gp before calling the __error, and that will need a stack frame. I've attached a patch that should fix this for o32 ABI - but it really should be written with ABI-independent macros, any clue on how to do this which will take care of n32/64 too will be helpful. I also have some initial patches for making gdb work on MIPS. . That patch is also attached, but it is work in progress, only the static executables work now. JC. --000e0cd11bb4a9c925047ea9800a--
