Ok, so the tempation to quote the excelent “I need a hole in my head” blog
masthead is too great to avoid and I appologize in advance but gosh, I need
a hole in my head!
somebody call the compiler guys and let them know that __forceinline (or in
DDK land FORCEINLINE) really ought to do just that!
You know what the otherwise excelent wdfkd.wdfspinlock extension tells me is
the callers address in a debug build? (drum roll…)
!WdfSpinLockAcquire(). Geez, that is useful.
But seriously, does anyone have any suggestions on how to leverage this
capability when working with a debug build other than forcing /Ob1 for the
entire build or is that the only way? I would, of course, like to have my
cake and eat it too. I use FORCEINLINE functions all over the place and I
don’t want to unecessarilly expand them all (but that is where I am going
now until I find this spinlock issue).
TIA,

By design that FORCEINLINE evaluates to a real symbol on a chk build,
makes debugging easier, but as you point out, it has unintended
sideaffects. I don’t have a good solution on how to overcome this
feature on chk build and get the real caller’s address
