Hi,
patch below makes GDB single stepping for MIPS work.
For debugging (breakpoint set), in
target-mips/translate.c/gen_intermediate_code_internal()
gen_opc_pc[] isn't initialized. So in debugging case don't call
cpu_restore_state() which then accesses uninitalized
gen_opc_pc[]. do_raise_exception_direct() indirectly calls
cpu_restore_state(), do_raise_exception() doesn't.
Best regards
Dirk
