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
