X-Git-Url: https://git.stderr.nl/gitweb?a=commitdiff_plain;ds=sidebyside;p=matthijs%2Fmaster-project%2Fc%CE%BBash.git Really revert all of the recent rotating changes. Some minor structural and comment changes were left, no functional changes, though. --- diff --git a/clash/CLasH/VHDL/Generate.hs b/clash/CLasH/VHDL/Generate.hs index b6aa8c6..c56bdbe 100644 --- a/clash/CLasH/VHDL/Generate.hs +++ b/clash/CLasH/VHDL/Generate.hs @@ -310,9 +310,8 @@ mkConcSm (bndr, expr@(CoreSyn.Case (CoreSyn.Var scrut) _ _ alts)) = do -- Compare the (constructor field of the) scrutinee with each of the -- alternatives. let cond_exprs = map (\x -> cmp AST.:=: x) altcons - -- Rotate expressions to the leftso that the expression related to the default case is the last - let alts' = (tail alts) ++ [head alts] - exprs <- MonadState.lift tsType $ mapM (varToVHDLExpr .
