This gets gdbstub working at least to the point where clients can
communicate with it.
What works:
- Reading/writing GPRegs
- Reading/writing memory
- Interrupting the emulated program and continuing
What does NOT work:
- Breakpoints. Sizes have been updated to u64, but support will need to be
added in the interpreter for them to work.
- VRegs. Mostly because my gdb was having issues with 128-bit regs for
some reason. However, the current u128 representation is a bit
awkward to use and should probably be updated first.
Corrects a few issues with regards to Doxygen documentation, for example:
- Incorrect parameter referencing.
- Missing @param tags.
- Typos in @param tags.
and a few minor other issues.
Currently, this is only ever queried, so adding a function to check if the
server is enabled is more sensible.
If directly modifying this externally is ever desirable, it should be done
by adding a function to the interface, rather than exposing implementation
details directly.
Previously, the padding wasn't correctly accounted for which caused the gdbstub to read and write everything after R15 (starting with the dummy FPA registers) incorrectly, which caused CPSR to not be handled correctly. Everything appears to be working as expected with this change.
