The executables precompile Qt since #7235, but the libcockatrice_* static libraries still reparse the full Qt Core stack in every TU. Measured over the tree after the IWYU pass: 380 MB of header parse in the libraries, 92% of it reachable from qtcore_pch.h. - Apply qtcore_pch.h to the 14 Qt Core static library targets (skips libcockatrice_rng: its SFMT.c is C and cannot use a C++ precompiled header). - Grow qtcore_pch.h with 25 QtCore headers that IWYU shows are re-parsed across many TUs and were not already reachable from the existing list (JSON/QUuid cluster, QSettings, item models, threading, XmlStream, QTemporaryDir, ...). - Grow qtwidgets_pch.h with 30 QtGui/QtWidgets headers (dialog cluster, item views, QImageReader, ...). Only stable Qt headers go into the PCH, so it rarely invalidates. Test executables stay PCH-less: 1-3 TUs per target does not amortize the extra precompile.

/** @file qtcore_pch.h
|
|
* @brief Precompiled header for all Qt targets (Qt Core only).
|
|
*
|
|
* Safe for every target that links Qt Core, including the headless
|
|
* Servatrice binary. Keep this header free of any widget/gui types.
|
|
*
|
|
* Candidates are chosen from IWYU include statistics: a header earns a
|
|
* spot when it is not already reachable from the rest of this list and
|
|
* enough translation units re-parse it. Qt headers are stable across
|
|
* builds, so the precompiled header rarely invalidates.
