Introduction

This document contains the release notes for the language interoperability library CppInterOp, release 1.6.0. CppInterOp is built on top of Clang and LLVM compiler infrastructure. Here we describe the status of CppInterOp in some detail, including major improvements from the previous release and new feature work. Note that if you are reading this file from a git checkout, this document
applies to the next release, not the current one.

CppInterOp exposes API from Clang and LLVM in a backward compatibe way. The API support downstream tools that utilize interactive C++ by using the compiler as a service. That is, embed Clang and LLVM as a libraries in their codebases. The API are designed to be minimalistic and aid non-trivial tasks such as language interoperability on the fly. In such scenarios CppInterOp can be used to provide the necessary introspection information to the other side helping the language cross talk.

What's New in CppInterOp 1.6.0?

Some of the major new features and improvements to CppInterOp are listed here. Generic improvements to CppInterOp as a whole or to its underlying infrastructure are described first.

External Dependencies

  • CppInterOp now works with:
    • llvm19

Introspection

  • Added IsPointerType and GetPointerType functions.
  • Added IsReferenceType and GetNonReferenceType functions.
  • Introduced IsFunctionPointerType function.
  • Implemented GetEnumConstantDatamembers function to resolve all EnumConstantDecls declared in a class.
  • Added IsClassPolymorphic function.

Just-in-Time Compilation

  • Introduced Demangle function for handling name demangling.

Incremental C++

  • Code generation fixes for MakeFunctionCallable for template operators and incorrect handling when the return type is a function pointer.

Misc

  • Fixed a bug preventing users from disabling testing in CMake.
  • Prefixed interpreter CMake option for better clarity.
  • Multiple improvements in the continuous integration infrastructure including
    compilation times, cache sizes, added new jobs for arm.
