This is an automated email from the git hooks/post-receive script. x2go pushed a commit to branch upstream/28.4.1 in repository pale-moon. commit 80dfca45772a4d4fc5fd61630e2a812e779ec620 Author: wolfbeast <mcwerewolf@wolfbeast.com> Date: Thu Mar 21 09:53:24 2019 +0100 Pref the use of unboxed plain objects in JS and disable by default. This should be all that's needed for #1017, but verification of impact is definitely desired. --- js/src/jit/JitOptions.cpp | 2 +- js/src/jsapi.cpp | 3 +++ js/src/jsapi.h | 25 +++++++++++++------------ js/xpconnect/src/XPCJSContext.cpp | 4 ++++ modules/libpref/init/all.js | 1 + 5 files changed, 22 insertions(+), 13 deletions(-) diff --git a/js/src/jit/JitOptions.cpp b/js/src/jit/JitOptions.cpp index eb5a6c1..b9a7c7b 100644 --- a/js/src/jit/JitOptions.cpp +++ b/js/src/jit/JitOptions.cpp @@ -222,7 +222,7 @@ DefaultJitOptions::DefaultJitOptions() } // Toggles whether unboxed plain objects can be created by the VM. - SET_DEFAULT(disableUnboxedObjects, false); + SET_DEFAULT(disableUnboxedObjects, true); // Test whether Atomics are allowed in asm.js code.
