Shared by the [Digital Mars C compiler](https://github.com/DigitalMars/Compiler/), but not [LDC](https://github.com/ldc-developers/ldc) or [GDC](https://gdcproject.org/). | | [dmd/common/](https://github.com/dlang/dmd/tree/master/compiler/src/dmd/common) | Code shared by the front-end and back-end | | [dmd/root/](https://github.com/dlang/dmd/tree/master/compiler/src/dmd/root) | Meant as a portable utility library, but ["it wasn't very good and the only project left using it is dmd"](https://github.com/dlang/dmd/pull/9844#issuecomment-498479516). | DMD has a mostly flat directory structure, so this section aims to divide all source files into logical groups for easier navigation. The groups are roughly ordered by how late they appear in the compilation process. Note that these groups have no strict meaning, the category assignments are a bit subjective. ### Driver | File | Purpose | |-----------------------------------------------------------------------------|-----------------------------------------------------------------------| | [mars.d](https://github.com/dlang/dmd/blob/master/compiler/src/dmd/mars.d) | The entry point.
