[cfe-dev] Question about contribution

[Stephen Kelly via cfe-dev]

If you go with a clang-tidy check (seems appropriate) you would need to 
write AST Matchers to find the places in code to transform, and then 
make transformations at the appropriate source locations.

This gives you a start in the former: http://ce.steveire.com/z/d3njX8

and http://ce.steveire.com/z/qJd39w with the latter and see

  https://steveire.wordpress.com/2019/04/30/the-future-of-ast-matching-refactoring-tools-eurollvm-and-accu/

for more.

Thanks,

Stephen
