Below is a list of areas where LLILC needs work. Their order follows the path to creating a functioning JIT, that can compile most C# programs; and doing so with contributions from the Community - so good documentation comes early. Each item is given a "star" rating: 1 star denotes easy; many stars denote challenging.
We always keep a list of open issues in the repo, to track open work items. This is a good place to start. But beware that it changes day-by-day. So if you spot an item you'd like to work on, assign it to yourself, so everyone can see it's being worked on.
As you work on an issue, it will likely spawn more work. So enter these as issues.
-
(*) Areas where documentation needs improving. Eg: #122, #124, #128, #129, #130, #131, #145, #154, #174, #175, #176
-

-
(**) Memory allocation #233

-
(*) Add benchmarks for optimization
-
(**) Add web-crawler to harvest MSIL tests and execute
-
(***) Generator for random (but legal) MSIL code #503
-
(**) Bugs
- If you want to fix an existing bug, assign to yourself and go
- If you find a new bug, please check it's not a duplicate, then enter as an issue, with as simple a repro as you can devise
-
(**) NGEN support #287
