Hi all, Can someone walk me through in a friendly way how to check the assembly produced by dmd? The application in this case is checking some new patches to Phobos. It's something I'm not familiar with doing in general and particularly not with dmd (which doesn't seem to have an assembly-output switch), so I'm hoping someone can advise :-) Thanks & best wishes, -- Joe

There is obj2asm by Walter, but it is part of the paid Digital Mars package (AFAIK). objconv[1] should work though, and it is free. Alternatively, if you don't mind GDC-generated assembly, you can do it online quite easily[2]. [1]: http://www.agner.org/optimize/ [2]: http://d.godbolt.org/

I'm running latest git-HEAD self-compiled DMD, so I never download any of the packages.
