digitalmars.D - Ldc vs dmd vs gdc
- Rikki Cattermole (11/11) Dec 15 2014 I found a little interesting difference between ldc, dmd and gdc today.
- Rikki Cattermole (5/20) Dec 25 2014 Could really use an answer to this.
- Iain Buclaw via Digitalmars-d (8/22) Dec 26 2014 function prototypes with different parameters but same mangling aka name...
- Rikki Cattermole (3/28) Dec 26 2014 This is the answer I was looking for thank you. Just needed somebody to

I found a little interesting difference between ldc, dmd and gdc today. Summarized in ldc it does not allow you to have multiple extern c'd function prototypes with different parameters but same mangling aka name. In dmd and gdc it compiles fine. I believe this is actually wrong. As c abi does not support overloading of functions, shouldn't the compilers at the very least report a warning of this?

The frontend should at least disallow conflicting extern(C) prototypes.
