Details |
We currently inline megamorphic cache lookups in Ion. This bug tracks inlining megamorphic cache lookups in Baseline as well. Initial experimentation with this showed neutral/negative results. However, after tuning things a bit and eliminating the redundant extra cache lookups by passing the cache entry pointer from JIT to C++, I'm actually seeing some promising results here.
