From 1c3c106fc896453e6e9b8dd5914eddf5b20d2416 Mon Sep 17 00:00:00 2001 From: Vladimir Marko Date: Tue, 3 Dec 2019 11:18:44 +0000 Subject: jni: Do not create a managed frame for @CriticalNative. Omit managed frame for @CriticalNative methods, do not check for exceptions and and make a tail call when possible. Pass the method pointer in a hidden argument to prepare for implementing late binding for @CriticalNative methods. This changes only the JNI compiler, Generic JNI shall be updated in a separate change.
