...ssible to lower all OpenMP directives to the above four intrinsics in the frontend (please read this in conjunction with [1]): Parallel regions can be lowered as a parallel_map with @llvm.num_threads as the limit. ``` #pragma PARALLEL block ``` desugars to ``` @llvm.parallel_map(num_threads, block_closure, shared_closure) ... void block_closure(i32 tid, i8* shared_vars) { block } ``` Reductions are handled by a parallel_map followed by a regular reduction loop (exactly as in Hal's proposal). Serial blocks reduce to a block conditional on the index inside the function being parallelly mapped...
