My Clang Contributions

• clang tooling library:
  • AST matchers:
    • extend hasType to work with TypedefDecl nodes
    • add functionProtoType matcher for matching FunctionProtoType nodes
    • extend parameterCountIs matcher to FunctionProtoType nodes
• clang-tidy checks:
  • modernize-macro-to-enum converts groups of macros to unscoped anonymous enums
• modernize-raw-string-literal converts string literals with escaped characters to raw string literals

Case Study

• Our case study is the open source fractal generator Iterated Dynamics, a fork of FRACTINT.
• This is a 30 year old code base that started as a 16-bit MS-DOS program written in C and 16-bit x86 assembly.
• The code base has contributions from many, many authors over the years.
• Source formatting and identifier conventions are varied due to the large number of authors.
• Source code organization has been tortured by the constraints of early MS-DOS programs operating in a limited amount of physical memory and the use of overlays.
• Conditional compilation was sprinkled throughout to enable various debugging facilities or experiments in alternative implementations.
• As C does not have inline functions, there are some places that heavily use preprocessor macros.
• Some of the functions are [exceedingly long*](https://github.com/LegalizeAdulthood

A colleague discovered that switching from `-stc=c++17` to `-std=c++20` 
in their project resulted in a different behavior from some associative 
containers. A bit of research allowed to narrow down the culprit to what 
can be demonstrated by the following minimalist example
