[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
