Subject: Introduce tui_source_window_base::location_matches_p method
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c2cd8994669f63eb415522352a5d5006d0fbfb48;p=binutils-gdb.git

Introduce tui_source_window_base::location_matches_p method

This introduces the location_matches_p method, removing a spot that
explicitly examines a window's type.
