toBlockList :: CmmGraph -> [CmmBlock] Source

bodyToBlockList :: Body CmmNode -> [CmmBlock] Source

toBlockListEntryFirst :: CmmGraph -> [CmmBlock] Source

like toBlockList, but the entry block always comes first

toBlockListEntryFirstFalseFallthrough :: CmmGraph -> [CmmBlock] Source

Like toBlockListEntryFirst, but we strive to ensure that we order blocks so that the false case of a conditional jumps to the next block in the output list of blocks. This matches the way OldCmm blocks were output since in OldCmm the false case was a fallthrough, whereas in Cmm conditional branches have both true and false successors. Block ordering can make a big difference in performance in the LLVM backend. Note that we rely crucially on the order of successors returned for CmmCondBranch by the NonLocal instance for CmmNode defind in cmm/CmmNode.hs. -GBM
