Note that GDB at least implements single stepping for MIPS using software breakpoints explicitly rather than using PT_STEP, so this has only been tested via tests in ptrace_test which now pass rather than fail. - Fix several places to use uintptr_t instead of int for virtual addresses. - Check for errors from ptrace_read_int() when setting a breakpoint for a step. - Properly check for errors from ptrace_write_int() as it returns non-zero, not negative values on failure. - Change the error returns for ptrace_read_int() and ptrace_write_int() from ENOMEM to EFAULT. - Clear a single step breakpoint when it traps rather than waiting for it to be cleared from ptrace(). This matches the behavior of the arm port and in general seems a bit more reliable than waiting for ptrace() to clear it via FIX_SSTEP. - Drop the PROC_LOCK around ptrace_write_int() in ptrace_clear_single_step() since it can sleep. - Reorder the breakpoint handler in trap() to only read the instruction if the address matches the current thread's breakpoint address. - Replace various #if 0'd debugging printfs with KTR_PTRACE traces. Tested on: mips64 |
