[LLVMdev] The implementation algorithm behind LLVM's RegionInfo class
Hi Tobi, I have one additional question about the RegionInfo::isRegion function. In the second case (i.e. Entry dominates Exit), why is checking the following two conditions are equivalent to checking it's a refined region: For any BB in DF(exit), 1) BB should be in DF(entry) 2) BB reachable only from entry through a path pas...

[LLVMdev] The implementation algorithm behind LLVM's RegionInfo class
Hi Tobias, Thanks a lot for the detailed reply. I am working on several new optimizations for OpenCL kernels for a DSP architecture. The project itself has an NDA associated with it, so I cannot go into more details, but the source will be open to public after completion. One of the first steps is to serialize the work-items in a work-group (e.g., insert nested loops around REGIONs in
