2018-02-04mjit_compile.c: merge initial JIT compilerk0kubun
which has been developed by Takashi Kokubun <takashikkbn@gmail> as YARV-MJIT. Many of its bugs are fixed by wanabe <s.wanabe@gmail.com>. This JIT compiler is designed to be a safe migration path to introduce JIT compiler to MRI. So this commit does not include any bytecode changes or dynamic instruction modifications, which are done in original MJIT. This commit even strips off some aggressive optimizations from YARV-MJIT, and thus it's slower than YARV-MJIT too. But it's still fairly faster than Ruby 2.5 in some benchmarks (attached below). Note that this JIT compiler passes `make test`, `make test-all`, `make test-spec` without JIT, and even with JIT. Not only it's perfectly safe with JIT disabled because it does not replace VM instructions unlike MJIT, but also with JIT enabled it stably runs Ruby applications including Rails applications. I'm expecting this version as just "initial" JIT compiler. I have many optimization ideas which are skipped for initial merging, and you may easily replace this JIT compiler with a faster one by just replacing mjit_compile.c. `mjit_compile` interface is designed for the purpose. common.mk: update dependencies for mjit_compile.c. internal.h: declare `rb_vm_insn_addr2insn` for MJIT. vm.c: exclude some definitions if `-DMJIT_HEADER` is provided to compiler. This avoids to include some functions which take a long time to compile, e.g. vm_exec_core. Some of the purpose is achieved in transform_mjit_header.rb (see `IGNORED_FUNCTIONS`) but others are manually resolved for now. Load mjit_helper.h for MJIT header. mjit_helper.h: New. This is a file used only by JIT-ed code. I'll refactor `mjit_call_cfunc` later. vm_eval.c: add some #ifdef switches to skip compiling some functions like Init_vm_eval. win32/mkexports.rb: export thread/ec functions, which are used by MJIT. include/ruby/defines.h: add MJIT_FUNC_EXPORTED macro alis to clarify that a function is exported only for MJIT. array.c: export a function used by MJIT. bignum.c: ditto. class.c: ditto. compile.c: ditto. error.c: ditto. gc.c: ditto. hash.c: ditto. iseq.c: ditto. numeric.c: ditto. object.c: ditto. proc.c: ditto. re.c: ditto. st.c: ditto. string.c: ditto. thread.c: ditto. variable.c: ditto. vm_backtrace.c: ditto. vm_insnhelper.c: ditto. vm_method.c: ditto. I would like to improve maintainability of function exports, but I believe this way is acceptable as initial merging if we clarify the new exports are for MJIT (so that we can use them as TODO list to fix) and add unit tests to detect unresolved symbols. I'll add unit tests of JIT compilations in succeeding commits. Author: Takashi Kokubun <takashikkbn@gmail.com> Contributor: wanabe <s.wanabe@gmail.com> Part of [Feature #14235] --- * Known issues * Code generated by gcc is faster than clang. The benchmark may be worse in macOS. Following benchmark result is provided by gcc w/ Linux. * Performance is decreased when Google Chrome is running * JIT can work on MinGW, but it doesn't improve performance at least in short running benchmark. * Currently it doesn't perform well with Rails.

TL;DR see http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2031.htm Suppose we have: struct X { struct Y { z_t z; } y; } x; then, you _cant_ infer offsetof(struct X, y.z). The ISO C99 section 7.17 says nothing about such situation. At least clang warns this being an extension to the language (-Wextended-offsetof). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61560 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

We cannot assume autoload_provided/rb_feature_provided returning TRUE means it is safe to proceed without waiting. Another thread may call rb_provide_feature before setting the constant (via autoload_const_set). So we must wait until autoload is completed by another thread.

2016-11-29Stop reading past the end of `ivptr` arraytenderlove
If you have code like this: ```ruby class A def initialize @a = nil @b = nil @c = nil @d = nil @e = nil end end x = A.new y = x.clone 100.times { |z| x.instance_variable_set(:"@foo#{z}", nil) } puts y.inspect ``` `x` and `y` will share `iv_index_tbl` hashes. However, the size of the hash will grow larger than the number if entries in `ivptr` in `y`. Before this commit, `rb_ivar_count` would use the size of the hash to determine how far to read in to the array, but this means that it could read past the end of the array and cause the program to segv [ruby-core:78403] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@56938 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2016-01-12resolve class name earlier and more consistentlynormal
This further avoids class name resolution issues which came about due to relying on hash table ordering before r53376. Pre-caching the class name when it is never used raises memory use, but the overall gain from moving away from st still gives us a small gain.
