The functions all reported not being inlined due to 'dllimport check failed'.
Testing with this, and a small class that uses various QRect(F) members:
cl.exe /nologo /O2 /Ob2 /std:c++20 /Zc:__cplusplus /EHsc /MD
/I "C:\projects\qt\dev\build-release\qtbase\include"
/I "C:\projects\qt\dev\build-release\qtbase\include\QtCore"
/D QT_CORE_LIB /D UNICODE /D _UNICODE
/d2inlinestats /d2cgsummary
/FAcs /Fa"C:\temp\qrectf_test.asm"
/c "C:\temp\qrectf_test.cpp"
/Fo"C:\temp\qrectf_test.obj"
The /d2inlinestats /d2cgsummary are the ones that output details on the
inlining.

That's strange - why does it work with QRectF then?
