* [PATCH v13a 2/9] ci: Use meson for most of CompilerWarnings, it's a lot faster
@ 2026-06-09 14:18 Andres Freund <andres@anarazel.de>
  0 siblings, 0 replies; 515+ messages in thread

From: Andres Freund @ 2026-06-09 14:18 UTC (permalink / raw)

Previously, with a cold cache or a change in a central header, the
CompilerWarnings job would take ~35 minutes. The worst aspect of that was the
windows cross build, which would take about 8-10 minutes.

Migrate the compiler warnings tasks to meson, that generally makes the
cold-cache build a bit faster, and makes the windows cross build a *lot*
faster, due to being able to use precompiled headers.

With that the cold cache performance improves to about 12 minutes.
