Single stepping command were used for next_pc in straight line code, with imm instruction and the branch with delay Slot.
Your terminology may be a bit confusing. Gdbserver
is a program (part of GDB) which runs on a platform (e.g.
Linux), and which implements the GDB Remote Serial Protocol.
XMD does not run gdbserver. It has an independent implementation
of the GDB Remote Serial Protocol. It would be better to
say that XMD is a remote stub.
Please provide a disassembly of the test case and
a log of the commands to gdb and gdb's output, showing
stepping over imm and delay slot instructions.
Is there a test case which shows single stepping failing
without the patch?
Even better would be to update the gdb regression
test suite with the test case.
