This repo contains a version of clang that is being modified to support Checked C. Checked C extends C with checking to detect or prevent common programming errors such as out-of-bounds memory accesses. The Checked C specification is available at the Checked C repo.
On January 25, 2019, we updated to LLVM/clang sources from January 16, 2019. If you are building the Checked C clang compiler from source code, we suggest you do a clean build by deleting your cmake object directory.
We have a position available for a Principal Software Engineer or a Senior Software Engineer. We are looking for someone wih compiler and programming language implementation experience who is passionate about making software more secure and reliable.
Programmers are welcome to ``kick the tires'' on Checked C as it is being implemented. We have pre-built compiler installers for Windows available for download on the release page. For other platforms, you will have to build your own copy of the compiler. For directions on how to do this, see the Checked C clang wiki. The compiler user manual is here. For more information on Checked C and pointers to example code, see our Wiki.
For more information on the Checked C clang compiler, see the Checked C clang wiki.
