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?

-o- does skip codegen already....

DMD does inlining in the frontend, and without the That's not what causes the long compile time though, I was aware (and am not a fan of) inlining in the frontend, but didn't look at the Phobos code. 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 |

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 |
