[Sema] #pragma clang transform
Needs ReviewPublic

Authored by Meinersbur on Oct 17 2019, 12:29 AM.



Add the AST node kinds: the Stmt representing the #pragma, the clauses and Transform. The latter represents the semantic analysis result similar to an ImplicitCast. Moreover, the AnalysisTransform component constructs a loop nest tree to which transformations are applied to such that Sema can warn about inconsistencies, e.g. there is no inner or ambiguous loops for unrollandjam.

  • Switch to Monorepo
  • Move Transform.h/cpp to clangBasic
  • Transform is not an AST node anymore, but created on demand using ExtractTransform
  • Remove handling of LoopHints (#pragma clang loop) and OpenMP (#pragma omp simd) to reduce the size of the patches. Compatibility with OpenMP is still a goal (to implement the upcoming OpenMP loop transformations such as #pragma omp tile), but for now they are handled by separate code paths.
  • Rework TransformedTree a bit
