|The frontend is written in C++.
|The frontend lexes and parses the input into an IR specific to this
|frontend known as gogo. It then runs a series of passes over the
|Finally it converts gogo to gcc's GENERIC. A goal is to move the gcc
|support code into a gcc-interface subdirectory. The gcc code will be
|put under the GPL. The rest of the frontend will not include any gcc
|Issues to be faced in this transition:
|* Representation of source locations.
| + Currently the frontend uses gcc's source_location codes, using the
| interface in libcpp/line-map.h.
|* Handling of error messages.
| + Currently the frontend uses gcc's error_at and warning_at
| + Currently the frontend uses gcc's diagnostic formatter, using
| features such as %<%> for appropriate quoting.
| + Localization may be an issue.
|This compiler works, but the code is a work in progress. Notably, the
|support for garbage collection is ineffective and needs a complete
|rethinking. The frontend pays little attention to its memory usage
|and rarely frees any memory. The code could use a general cleanup
|which we have not had time to do.
