In x64_tracers.cc:

Enable tracing:

#define ITRACE 1  <--- for only ppc instructions
#define DTRACE 1  <--- add HIR data

If tracing data, run with the following flags:

--store_all_context_values

By default, tracing will start at the beginning and only for the specified thread.

Change traced thread by thread creation ID:

#define TARGET_THREAD 4

To only trace at a certain point, change default trace flag to false:

bool trace_enabled = true;

Add a breakpoint:

--break_on_instruction=0x821009A4

On break, add the following to the Watch window and set it to true:

xe::cpu::backend::x64::trace_enabled

Continue, and watch stuff appear in the log.
