2021-01-05enable constant cache on ractorsKoichi Sasada
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.

2020-12-14Skip defined check in NODE_OP_ASGN_OR with ivarJohn Hawthorn
Previously we would add code to check if an ivar was defined when using `@foo ||= 123`, which was slower than `@foo || (@foo = 123)` when `@foo` was already defined. Recently 01b7d5acc702df22d306ae95f1a9c3096e63e624 made it so that accessing an undefined variable no longer generates a warning, making the defined check unnecessary and both statements exactly equal. This commit avoids emitting the defined instruction when compiling NODE_OP_ASGN_OR with a NODE_IVAR. Before: $ ruby --dump=insn -e '@foo ||= 123' == disasm: #<ISeq:<main>@-e:1 (1,0)-(1,12)> (catch: FALSE) 0000 putnil ( 1)[Li] 0001 defined instance-variable, :@foo, false 0005 branchunless 14 0007 getinstancevariable :@foo, <is:0> 0010 dup 0011 branchif 20 0013 pop 0014 putobject 123 0016 dup 0017 setinstancevariable :@foo, <is:0> 0020 leave After: $ ./ruby --dump=insn -e '@foo ||= 123' == disasm: #<ISeq:<main>@-e:1 (1,0)-(1,12)> (catch: FALSE) 0000 getinstancevariable :@foo, <is:0> ( 1)[Li] 0003 dup 0004 branchif 13 0006 pop 0007 putobject 123 0009 dup 0010 setinstancevariable :@foo, <is:0> 0013 leave This seems to be about 50% faster in this benchmark: require "benchmark/ips" class Foo def initialize @foo = nil end def test1 @foo ||= 123 end def test2 @foo || (@foo = 123) end end FOO = Foo.new Benchmark.ips do |x| x.report("test1", "FOO.test1") x.report("test2", "FOO.test2") end Before: $ ruby benchmark_ivar.rb Warming up -------------------------------------- test1 1.957M i/100ms test2 3.125M i/100ms Calculating ------------------------------------- test1 20.030M (± 1.7%) i/s - 101.780M in 5.083040s test2 31.227M (± 4.5%) i/s - 156.262M in 5.015936s After: $ ./ruby benchmark_ivar.rb Warming up -------------------------------------- test1 3.205M i/100ms test2 3.197M i/100ms Calculating ------------------------------------- test1 32.066M (± 1.1%) i/s - 163.440M in 5.097581s test2 31.438M (± 4.9%) i/s - 159.860M in 5.098961s Notes: Merged: https://github.com/ruby/ruby/pull/3904

* `GC.auto_compact=`, `GC.auto_compact` can be used to control when compaction runs. Setting `auto_compact=` to true will cause compaction to occurr duing major collections. At the moment, compaction adds significant overhead to major collections, so please test first! [Feature #17176]

2020-10-17sync RClass::ext::iv_index_tblKoichi Sasada
iv_index_tbl manages instance variable indexes (ID -> index). This data structure should be synchronized with other ractors so introduce some VM locks. This patch also introduced atomic ivar cache used by set/getinlinecache instructions. To make updating ivar cache (IVC), we changed iv_index_tbl data structure to manage (ID -> entry) and an entry points serial and index. IVC points to this entry so that cache update becomes atomically. Notes: Merged: https://github.com/ruby/ruby/pull/3662

2020-09-03Introduce Ractor mechanism for parallel executionKoichi Sasada
This commit introduces Ractor mechanism to run Ruby program in parallel. See doc/ractor.md for more details about Ractor. See ticket [Feature #17100] to see the implementation details and discussions. [Feature #17100] This commit does not complete the implementation. You can find many bugs on using Ractor. Also the specification will be changed so that this feature is experimental. You will see a warning when you make the first Ractor with `Ractor.new`. I hope this feature can help programmers from thread-safety issues. Notes: Merged: https://github.com/ruby/ruby/pull/3365

2020-07-03Use ID instead of GENTRY for gvars. (#3278)Koichi Sasada
Use ID instead of GENTRY for gvars. Global variables are compiled into GENTRY (a pointer to struct rb_global_entry). This patch replace this GENTRY to ID and make the code simple. We need to search GENTRY from ID every time (st_lookup), so additional overhead will be introduced. However, the performance of accessing global variables is not important now a day and this simplicity helps Ractor development. Notes: Merged-By: ko1 <ko1@atdot.net>
