> This PR removes some unnecessary coupling between Lower, Gen and > LocalProxyVarsGen. > > It does so by making LocalProxyVarsGen no longer a standalone pass but, > rather, a helper for Gen::normalizeMethod. > > The main idea is that we can make things more regular, by having Gen always > inserting variable initializer in the correct place. > Then, LocalProxyVarGen will create a blank proxy, and use its visitor to > inspect the rest of the constructor body. > Since the visitor _already_ rewires assignments to real fields as assignments > to proxies, this new arrangement has the desired effect of generating the > same code as before, but w/o too much coupling. > > Some massaging to `Gen::normalizeMethod` was needed because now we need to > make sure it calls the proxy step for all constructors, not just in case > there's some pending var initializers. > > Finally, when cleaning up `Lower` I noticed a likely bug: `freevardefs` was > no longer preserving the `LOCAL_CAPTURE_FIELD` -- sometimes it was replacing > it with `STRICT`. But `LOCAL_CAPTURE_FIELD` is used by LambdaToMethod, so > changing this probably results in bad downstream lowering. > I've fixed this by adding both `STRICT` _and_ `LOCAL_CAPTURE_FIELD` to the > captured sym. > > --------- > - [x] I confirm that I make this contribution in accordance with the [OpenJDK > Interim AI Policy](https://openjdk.org/legal/ai).
