From 64d6e187f19ed670429652020561887e6b220216 Mon Sep 17 00:00:00 2001 From: Vladimir Marko Date: Thu, 14 Oct 2021 09:32:01 +0100 Subject: JNI: Remove `JniMethodFast{Start,End}()`. Inline suspend check from `GoToRunnableFast()` to JNI stubs. The only remaining code in `JniMethodFast{Start,End}()` is a debug mode check that the method is @FastNative, so remove the call altogether as we prefer better performance over the debug mode check. Replace `JniMethodFastEndWithReference()` with a simple `JniDecodeReferenceResult()`.
