[PATCH 2/3] tests/tcg: Factor out gdbstub test functions

[PATCH 2/3] tests/tcg: Factor out gdbstub test functions |
|
Date: |
Tue, 9 Jan 2024 00:34:07 +0100 |
Both the report() function as well as the initial gdbstub test sequence
are copy-pasted into ~10 files with slight modifications. This
indicates that they are indeed generic, so factor them out. While
at it, add a few newlines to make the formatting closer to PEP-8.
