1772252 - the argument --debugger-args seems to have broken (and it doesn't show up in help)

Status: NEW

(Testing :: General, defect, P3)

Description

[Randell Jesup [:jesup] (needinfo me)]

./mach test --debugger=rr --debugger-args="record --disable-avx-512" (for pernosco recordings) no longer works, because the args in --debugger-args aren't passed to the rr commandline.

This used to work. I see multiple references to --debugger-args in our python code, but ./mach test --help doesn't list --debugger-args. Thinking back, I think this has been broken for a while. (my "record -M" args weren't printing when values)

no error is given (it appears to accept it), but the args aren't included in the command line.

It can be worked around by modifying mozdebug.py to include:
"rr": {"interactive": True, "args": ["record", "--disable-avx-512"]},
in the _DEBUGGER_INFO array

I believe I was using xpcshell tests when I saw this, if it matters
