Placeholder for record style GADT declaration
A GADT Declaration is now presented as CmmCondBranch :: {..} -> CmmNode O C cml_pred :: CmmExpr cml_true, cml_false :: !Label cml_likely :: Maybe Bool for CmmCondBranch :: { -- conditional branch cml_pred :: CmmExpr, cml_true, cml_false :: ULabel, cml_likely :: Maybe Bool -- likely result of the conditional, -- if known } -> CmmNode O C
