...nto expected form. Rather than that, this proposal aims to address more high-level scope of use, where developers need to verify the consistency of many parts of compiler pipeline - from frontend to code generation. One natural solution might be to markup loops in high-level language: #pragma llvm loopname Loop1 for (int i = 0; i < n; i++) { ... } and pass this name through the frontend to LLVM IR metadata node or annotation intrinsic attached to the loop header. In order to support multiple target languages (we are mostly interested in C and Fortran), it is preferred to have GCC frontend su...
