Use jit interface thunkgen tech for more files by davidwrighton · Pull Request #45044 · dotnet/runtime

davidwrighton · 2020-11-21T01:47:40Z

Reduce the boilerplate logic when modifying the jit ee interface
3 new files in superpmi are now autogenerated as well as 2 files in the jit directory are now autogenerated
Reduce to only having one copy of the jit-ee interface guid

Thanks! I had been thinking we should do something like this for a long time.

Can you leave breadcrumbs here and in the other newly auto-generated files to hiht at how they can be regenerated?

Yes, please include pointers to the instructions for re-generation

https://github.com/dotnet/runtime/blob/master/docs/project/updating-jitinterface.md is the current doc if changes are needed there.

AndyAyersMS · 2020-11-21T02:28:09Z

@BruceForstall @sandreenko think you should look this over too.

jkotas · 2020-11-21T02:35:05Z

Unfortunately requires compiling the libjitinterface with the PAL

Why is that? That's very unfortunate.

I think depending on the PAL headers would be ok, but it would be really nice to avoid linking with the PAL. I was hoping that the number of places we link the PAL will decrease over time...

BruceForstall

This should make updating the JIT-EE interface easier, which is much appreciated.

nit? Looks like you could save lots of duplicated code by extracting a function to output function signatures, and function argument call lists

BruceForstall · 2020-11-24T18:28:45Z

src/coreclr/src/tools/Common/JitInterface/ThunkGenerator/Program.cs

Seems like you should have at least minimal argument validation here, like checking the number of arguments, and a "usage" message that would also serve as a short description of what this tool is doing.

looks good, I like the simplified jit ee interface changes.

src/coreclr/src/tools/aot/jitinterface/corinfoexception.h

question: why was it renamed?

CorInfoException is an enum type in corinfo.h

- Removes duplicate copy of jit ee api version guid - Sets up for making jit interface wrapper actually implement the jit interface Update generater to match previous manual modification Use ICorJitInfo interface for jit thunk directly instead of relying on parallel definition to match up - Found a bug in handling of TryResolveToken Generate api names Generate jit api wrapper from thunk generator Generate icorjitinfoimpl.h spmi counter shim icorjitinfo superpmi-shim-simple Update linux script Fix utf8 char out marshalling Builds on Linux but doesn't work Compile with PAL Respond to code review feedback

davidwrighton · 2020-12-01T00:38:58Z

Updated with code review feedback. I've stepped back from requiring the PAL, as that was causing odd problems. I may address that in a future change.

Nit: The indentation is off.

The generator is ugly enough as it is. Unless there is pushback, I'd prefer to leave the indentation.

Seems like the "END JITEEVersionIdentifier" comment needs to be in the jiteeversionguid.h file.

We probably should have big, unmiss-able, comments at the top of all the JIT-EE interface files pointing to the JIT-EE version, but that's somewhat unrelated; this system only works when code reviewers know to ask for an interface GUID change.

Maybe the jiteeversionguid.h file should also point to the updating-jitinterface.md documentation.

With dotnet#45044 it moved from corinfo.h to jiteeversionguid.h
