We've known for a long time that this is producing worse code with GCC because of how we implemented in Q_ASSUME_IMPL(). So bite the bullet and actually deprecate the macro, replacing all extant Q_ASSUME() with Q_ASSERT(). The replacement is in C++23. Backporting the support onto Q_ASSUME_IMPL was previously rejected by reviewers. [ChangeLog][Deprecation Notice] The Q_ASSUME() macro is deprecated. This macro has different side-effects depending on the compiler used (GCC compared to Clang and MSVC), and there are certain conditions under which GCC is known to produce worse code than if the macro was absent. To give a hint to the compiler for optimizations, use the C++23 [[assume]] attribute. Change-Id: I80612a7d275c41f1baf0fffd177a3a4ad819fb2d Reviewed-by: Volker Hilsheimer <volker.hilsheimer@qt.io> |
