This change enables the _POSIX_ dynamic loader plugin for _QNX_, and is the
fourth in a series of changes that look to facilitate remote debug of _AArch64_
targets on _QNX_.
_QNX Neutrino Real-Time Operating System_ is a commercial Unix-like real-time
operating system primarily targeting the embedded systems market including
automotive, medical devices, robotics, transportation, and industrial embedded
systems.
The series of changes in question looks to provision support for –
- Launching a debuggee
- Attaching to a debuggee
- Having the debuggee come up stopped at the entry point
- Setting breakpoints
- Stopping at breakpoints
- Reading/writing contents of/to the debuggee's memory
- Reading/writing contents of/to the debuggee's registers
- Reading/writing contents of/to the debuggee's variables
- Resuming the debuggee's execution
- Single-stepping the debuggee's execution
- Interrupting the debuggee's execution
- Dumping information pertaining to the debuggee's stack trace
Kindly note that _ptrace_ isn't available on QNX. Instead, _devctl_ can be
leveraged to observe and control the execution of a process under debug on
_QNX_.
Any additional support (including the facilitation of execution of tests) will
be the subject of future work.
