Add a mechanism to permit plugins running code between optimizations and the back-end passes. Implement this through the LLVM plug-in mechanism to make permit plugins to be written independently of the front-end. The primary motivation for this point is TPDE-LLVM, which substitutes the LLVM back-end (optionally falling back to it for unsupported IR). We have been distributing a Clang patch; but requiring a custom-build toolchain is impracticable for many users. Front-end adjustments will follow as separate patches.

This directory contains test cases for individual source features of LLVM. It is designed to make sure that the major components of LLVM support all of the features of LLVM, for very small examples. Entire programs should not go here. Regression tests for individual bug fixes should go into the test/Regression dir.
