Hello All I am looking for an LLVM pass that is able to detect branches whose condition is known if they are reached. To illustrate what I mean, I attached a screenshot showing a partial CFG of a function. The branch in basic block for.cond.cleanup3 tests the same condition as the branch in the entry block, and has the same target BB if the condition is false. Also, if you inspect the graph carefully, the basic block for.cond.cleanup3 cannot be reached unless the first branch condition was true. This means that the condition of the branch in f...

Hi all, Here''s a work in progress series whcih does a partial revert of the previous swiotlb changes, and does a partial replacement with Becky Bruce''s series. The most important difference is Becky''s use of phys_addr_t rather than page+offset to represent arbitrary pages. This turns out to be simpler. I didn''t replicate the map_single_page changes, since
