      Description

      From clang 8.0.0, the support for precompiled header has become quite stable, but Qt still prevent clang from using this feature. But if I enabled it manually when building Qt, clang will complaint about can't find "qt_pch.h". However, clang works well when building qmake with precompiled header enabled. Maybe there is something wrong with qmake?
