Config

Fields

• maxLookahead :: Int

  Maximum number of statements to look ahead for equality.

  Increasing this potentially finds more de-inlining opportunities but also drastically increases the cost of not finding any. This number does not matter if we always find an opportunity quickly.

• minRepeats :: Int

  Minimum number of times a piece of code needs to appear for it to be worth extracting into a function.

• maxRepeats :: Int

  Maximum number of initial repeats to use for maximization. If we find enough, we're happy and stop looking. Most of the time we'll find fewer than 10, but sometimes a bit of code is repeated a lot which would slow down the algorithm significantly.

• windowSize :: Int

  Number of statements in the sliding window.

defaultConfig :: Config

pass :: Annot a => Config -> GLSL a -> GLSL a

diTopDecl :: Annot a => Config -> TopDecl a -> TopDecl a

diStmts :: Annot a => Config -> [StmtAnnot a] -> [StmtAnnot a]

deleteBody :: Maybe ConstExprs -> [StmtAnnot a] -> [StmtAnnot a] -> [StmtAnnot a]

Remove all occurrences of body from ss.

findBody :: Config -> Maybe ConstExprs -> [StmtAnnot a] -> Maybe [StmtAnnot a]

transpose :: [[a]] -> [[a]]

allEqual :: Maybe ConstExprs -> [StmtAnnot a] -> Bool

Check for each statement whether it's structurally equal to the first one.
