Commit Message

David Malcolm Sept. 9, 2024, 11:48 p.m. UTC
Rename diagnostic_context's "printer" field to "m_printer",
for consistency with other fields, and to highlight places
where we currently use this, to help assess feasibility
of supporting multiple output sinks (PR other/116613).

No functional change intended.

Successfully bootstrapped & regrtested on x86_64-pc-linux-gnu.
Pushed to trunk as r15-3554-g19363bf5564ffb.
