Hi, Though PTRACE_SINGLESTEP is defined on MIPS Linux, the kernel does not support that kind of request. The ptrace call failed and sets errno to EIO and paused process is not resumed. In case of run-ptrace-mapper and run-ptrace-misc this leads to hanged execution because next call to wait4 never returns.
This change adds run-ptrace-mapper and run-ptrace-misc to the list of 'expected failed' tests on MIPS targets. -- Simon Atanasyan
