Honestly dmd shouldn't have an optimizer IMO, it's not fit for purpose anymore, if you want optimizations use GDC or LDC. Inlining doesn't even respect the semantics of the language IIRC DMD optimization are still valuable, DMD still compile faster than LDC/GDC For games it's even more important you don't want your debug build to run at 5 FPS

avoid codegen pass
hello, i run dmd from editor to check syntax of what i am writing, with -c -o-. how to run only semantic and avoid codegen to have a quicker run?
