I have a program where the various routines are all marked pragma( inline, true ). The compiler obeys this but the LDC and GDC compilers still compile the function bodies even though the bodies are not needed as they are supposed to be ‘private’ to the module, explicitly marked as such, hoping that that is like static in C. There are no pointers to the routines, so no need for the bodies because of any indirect calls. Is there a way to control this code bloat in LDC / GDC ? Using the godbolt compiler explorer with LDC and GDC I can indeed see that the code is being inlined. Does this count as a compiler performance-type bug?
This is with full -O3 optimisation and -release / -frelease for LDC and GDC respectively.
