Actually, I think this makes performance worse because it removes the "define". So there will be only one. I will fix it to maintain the macro. ---------------------------------------- Feature #16282: Add "call data" wrapper IMEMO object so inline cache can be updated https://bugs.ruby-lang.org/issues/16282#change-82360 * Author: tenderlovemaking (Aaron Patterson) * Status: Open * Priority: Normal * Assignee: * Target version: ---------------------------------------- Hi, Currently the compactor will invalidate all inline caches. I would like to update references in inline caches so we don't have to invalidate. Most inline caches are reachable from instruction sequences, but one cache is not: https://github.com/ruby/ruby/blob/6147fa82a923e7318f493857023006801ed25eb5/internal.h#L2395 This static variable can't be reached from the GC. I'd like to introduce a new IMEMO object that wraps this cache, then the GC can reach the cache and update the value. I've attached a patch that implements the new IMEMO object, and also removes the restriction on GCC so that all compilers get the cache hit. Does this seem OK shyouhei, ko1? ---Files-------------------------------- 0001-Wrap-call-data-with-an-IMEMO-object.patch (4.52 KB) -- https://bugs.ruby-lang.org/ Unsubscribe:
