# Updating RyuJIT
|
||
|
|
|
||
|
|
Following steps are necessary to pick up a new version of RyuJIT code generation backend from CoreCLR:
|
||
|
|
|
||
|
|
1. From the master branch of the CoreCLR repo, copy header files that are part of the contract with RyuJIT from `src\inc` on the CoreCLR side, to `src\JitInterface\src\ThunkGenerator` on the CoreRT side.
|
||
|
|
2. Inspect the diffs
|
||
|
|
1. If an enum was modified, port the change to the managed version of the enum manually.
|
||
|
|
2. If a JitInterface method was added or changed, update `src\JitInterface\src\ThunkGenerator\ThunkInput.txt` and run the generation script next to the file to regenerate `CorInfoBase.cs` and `jitinterface.h`. Update the managed implementation of the method in `CorInfoImpl.cs` manually.
|
||
|
|
3. If the JitInterface GUID was updated, update it in `src\Native\jitinterface\jitwrapper.cpp`
|
||
|
|
3. Go to https://dotnet.myget.org/feed/dotnet-core/package/nuget/Microsoft.NETCore.Jit and find the latest version of the RyuJIT package. Update the version number in dependencies.props at the root of the repo.
|
||
|
|
4. Rebuild everything and run tests to validate the change.
|
||
|
|
5. Create a pull request with title "Update RyuJIT".
