Introduce disposable call-cache. This patch contains several ideas: (1) Disposable inline method cache (IMC) for race-free inline method cache * Making call-cache (CC) as a RVALUE (GC target object) and allocate new CC on cache miss. * This technique allows race-free access from parallel processing elements like RCU. (2) Introduce per-Class method cache (pCMC) * Instead of fixed-size global method cache (GMC), pCMC allows flexible cache size. * Caching CCs reduces CC allocation and allow sharing CC's fast-path between same call-info (CI) call-sites. (3) Invalidate an inline method cache by invalidating corresponding method entries (MEs) * Instead of using class serials, we set "invalidated" flag for method entry itself to represent cache invalidation. * Compare with using class serials, the impact of method modification (add/overwrite/delete) is small. * Updating class serials invalidate all method caches of the class and sub-classes. * Proposed approach only invalidate the method cache of only one ME.

Add a cache for class variables Redo of 34a2acdac788602c14bf05fb616215187badd504 and 931138b00696419945dc03e10f033b1f53cd50f3 which were reverted. GitHub PR #4340. This change implements a cache for class variables. Previously there was no cache for cvars. Cvar access is slow due to needing to travel all the way up th ancestor tree before returning the cvar value. The deeper the ancestor tree the slower cvar access will be. The benefits of the cache are more visible with a higher number of included modules due to the way Ruby looks up class variables. The benchmark here includes 26 modules and shows with the cache, this branch is 6.5x faster when accessing class variables. ``` compare-ruby: ruby 3.1.0dev (2021-03-15T06:22:34Z master 9e5105c) [x86_64-darwin19] built-ruby: ruby 3.1.0dev (2021-03-15T12:12:44Z add-cache-for-clas.. c6be009) [x86_64-darwin19] | |compare-ruby|built-ruby| |:--------|-----------:|---------:| |vm_cvar | 5.681M| 36.980M| | | -| 6.51x| ``` Benchmark.ips calling `ActiveRecord::Base.logger` from within a Rails application.

VALUE size packed callinfo (ci). Now, rb_call_info contains how to call the method with tuple of (mid, orig_argc, flags, kwarg). Most of cases, kwarg == NULL and mid+argc+flags only requires 64bits. So this patch packed rb_call_info to VALUE (1 word) on such cases. If we can not represent it in VALUE, then use imemo_callinfo which contains conventional callinfo (rb_callinfo, renamed from rb_call_info). iseq->body->ci_kw_size is removed because all of callinfo is VALUE size (packed ci or a pointer to imemo_callinfo). To access ci information, we need to use these functions: vm_ci_mid(ci), _flag(ci), _argc(ci), _kwarg(ci). struct rb_call_info_kw_arg is renamed to rb_callinfo_kwarg. rb_funcallv_with_cc() and rb_method_basic_definition_p_with_cc() is temporary removed because cd->ci should be marked.

global call-cache cache table for rb_funcall* rb_funcall* (rb_funcall(), rb_funcallv(), ...) functions invokes Ruby's method with given receiver. Ruby 2.7 introduced inline method cache with static memory area. However, Ruby 3.0 reimplemented the method cache data structures and the inline cache was removed. Without inline cache, rb_funcall* searched methods everytime. Most of cases per-Class Method Cache (pCMC) will be helped but pCMC requires VM-wide locking and it hurts performance on multi-Ractor execution, especially all Ractors calls methods with rb_funcall*. This patch introduced Global Call-Cache Cache Table (gccct) for rb_funcall*. Call-Cache was introduced from Ruby 3.0 to manage method cache entry atomically and gccct enables method-caching without VM-wide locking. This table solves the performance issue on multi-ractor execution. [Bug #17497] Ruby-level method invocation does not use gccct because it has inline-method-cache and the table size is limited. Basically rb_funcall* is not used frequently, so 1023 entries can be enough. We will revisit the table size if it is not enough.

VALUE size packed callinfo (ci). Now, rb_call_info contains how to call the method with tuple of (mid, orig_argc, flags, kwarg). Most of cases, kwarg == NULL and mid+argc+flags only requires 64bits. So this patch packed rb_call_info to VALUE (1 word) on such cases. If we can not represent it in VALUE, then use imemo_callinfo which contains conventional callinfo (rb_callinfo, renamed from rb_call_info). iseq->body->ci_kw_size is removed because all of callinfo is VALUE size (packed ci or a pointer to imemo_callinfo). To access ci information, we need to use these functions: vm_ci_mid(ci), _flag(ci), _argc(ci), _kwarg(ci). struct rb_call_info_kw_arg is renamed to rb_callinfo_kwarg. rb_funcallv_with_cc() and rb_method_basic_definition_p_with_cc() is temporary removed because cd->ci should be marked.

Introduce disposable call-cache. This patch contains several ideas: (1) Disposable inline method cache (IMC) for race-free inline method cache * Making call-cache (CC) as a RVALUE (GC target object) and allocate new CC on cache miss. * This technique allows race-free access from parallel processing elements like RCU. (2) Introduce per-Class method cache (pCMC) * Instead of fixed-size global method cache (GMC), pCMC allows flexible cache size. * Caching CCs reduces CC allocation and allow sharing CC's fast-path between same call-info (CI) call-sites. (3) Invalidate an inline method cache by invalidating corresponding method entries (MEs) * Instead of using class serials, we set "invalidated" flag for method entry itself to represent cache invalidation. * Compare with using class serials, the impact of method modification (add/overwrite/delete) is small. * Updating class serials invalidate all method caches of the class and sub-classes. * Proposed approach only invalidate the method cache of only one ME. See [Feature #16614] for more details.

enable constant cache on ractors constant cache `IC` is accessed by non-atomic manner and there are thread-safety issues, so Ruby 3.0 disables to use const cache on non-main ractors. This patch enables it by introducing `imemo_constcache` and allocates it by every re-fill of const cache like `imemo_callcache`. [Bug #17510] Now `IC` only has one entry `IC::entry` and it points to `iseq_inline_constant_cache_entry`, managed by T_IMEMO object. `IC` is atomic data structure so `rb_mjit_before_vm_ic_update()` and `rb_mjit_after_vm_ic_update()` is not needed.

Use 1 byte hint for ar_table [Feature #15602] On ar_table, Do not keep a full-length hash value (FLHV, 8 bytes) but keep a 1 byte hint from a FLHV (lowest byte of FLHV). An ar_table only contains at least 8 entries, so hints consumes 8 bytes at most. We can store hints in RHash::ar_hint. On 32bit CPU, we use 4 entries ar_table. The advantages: * We don't need to keep FLHV so ar_table only consumes 16 bytes (VALUEs of key and value) * 8 entries = 128 bytes. * We don't need to scan ar_table, but only need to check hints in many cases. Especially we don't need to access ar_table if there is no match entries (in many cases). It will increase memory cache locality. The disadvantages: * This technique can increase `#eql?` time because hints can conflicts (in theory, it conflicts once in 256 times). It can introduce incompatibility if there is a object x where x.eql? returns true even if hash values are different. I believe we don't need to care such irregular case. * We need to re-calculate FLHV if we need to switch from ar_table to st_table (e.g. exceeds 8 entries). It also can introduce incompatibility, on mutating key objects. I believe we don't need to care such irregular case too. Add new debug counters to measure the performance: * artable_hint_hit - hint is matched and eql?#=>true * artable_hint_miss - hint is not matched but eql?#=>false * artable_hint_notfound - lookup counts

introduce TransientHeap. [Bug #14858] * transient_heap.c, transient_heap.h: implement TransientHeap (theap). theap is designed for Ruby's object system. theap is like Eden heap on generational GC terminology. theap allocation is very fast because it only needs to bump up pointer and deallocation is also fast because we don't do anything. However we need to evacuate (Copy GC terminology) if theap memory is long-lived. Evacuation logic is needed for each type. See [Bug #14858] for details. * array.c: Now, theap for T_ARRAY is supported. ary_heap_alloc() tries to allocate memory area from theap. If this trial sccesses, this array has theap ptr and RARRAY_TRANSIENT_FLAG is turned on. We don't need to free theap ptr. * ruby.h: RARRAY_CONST_PTR() returns malloc'ed memory area. It menas that if ary is allocated at theap, force evacuation to malloc'ed memory. It makes programs slow, but very compatible with current code because theap memory can be evacuated (theap memory will be recycled). If you want to get transient heap ptr, use RARRAY_CONST_PTR_TRANSIENT() instead of RARRAY_CONST_PTR(). If you can't understand when evacuation will occur, use RARRAY_CONST_PTR().

Introduce disposable call-cache. This patch contains several ideas: (1) Disposable inline method cache (IMC) for race-free inline method cache * Making call-cache (CC) as a RVALUE (GC target object) and allocate new CC on cache miss. * This technique allows race-free access from parallel processing elements like RCU. (2) Introduce per-Class method cache (pCMC) * Instead of fixed-size global method cache (GMC), pCMC allows flexible cache size. * Caching CCs reduces CC allocation and allow sharing CC's fast-path between same call-info (CI) call-sites. (3) Invalidate an inline method cache by invalidating corresponding method entries (MEs) * Instead of using class serials, we set "invalidated" flag for method entry itself to represent cache invalidation. * Compare with using class serials, the impact of method modification (add/overwrite/delete) is small. * Updating class serials invalidate all method caches of the class and sub-classes. * Proposed approach only invalidate the method cache of only one ME. See [Feature #16614] for more details.
