2018-02-09compile.c: popped hashnobu
* compile.c (compile_array): skip creating new hash if preceeding elements are popped all. [ruby-core:85486] [Bug #14459] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@62333 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
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.

2018-01-15__attibute__((__aligned__)) for RSTRING_PTR()shyouhei
For instance array.c:rb_ary_product() uses RSTRING_PTR() as an array of int. So to avoid misaligned memory access RSTRING_PTR() must at least be sizeof(int)-aligned. However the type of RSTRING_PTR() is char*, which of course can expect alignment as much as 1. This is a problem. The reality is, there is no misaligned memory access because the memory region behind RSTRING_PTR() is allocated using malloc(). Memory regions returned from malloc() are always aligned appropriately. So let's tell the compiler about this information. It seems GCC, clang, and MSVC have such feature. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61827 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2018-01-03compile.c: fix disasm dumpnobu
* compile.c (DECL_ANCHOR): initialize as anchor type, which is not a valid iseq element. * compile.c (BADINSN_DUMP): dump from the first element, excluding the anchor itself. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61584 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2018-01-02bit-fields other than int is a C99ismshyouhei
To be precise C90 says "A bit-field may have type int, unsigned int, or signed int". It is clear that char or enum are NG. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61554 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2018-01-01iseq.h: Extract position array from iseq_insn_info_entrymame
This makes TracePoint a bit fast by reducing cache misses of `get_insn_info_binary_search`. Also, I plan to use succinct bitvector algorithm for `get_insn_info` instead of binary search. This change will make it easy. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61536 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

This factors rb_iseq_constant_body#insns_info and #insns_info_size to struct iseq_insn_info. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61534 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2017-12-25Set first line numbers for empty iseqs.ko1
* compile.c (iseq_compile_each): for empty method, block and so on, `last_line` is not set so that line number of `putnil` instruction will be zero. This patch set `first_lineno` for such `putnil`. Problem is reported by deivid-rodriguez via Yuichiro Kaneko. * test/ruby/test_iseq.rb: add a test for this spec. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61457 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
