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 <>. 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. 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.

To convert the object implicitly, it has had two parts in convert_type() which are 1. lookink up the method's id 2. calling the method Seems that strncmp() and strcmp() in convert_type() are slightly heavy to look up the method's id for type conversion. This patch will add and use internal APIs (rb_convert_type_with_id, rb_check_convert_type_with_id) to call the method without looking up the method's id when convert the object.

In here, it has condition branch for shared / non shared Array object and it can use rb_ary_modify_check() which is smaller function than rb_ary_modify() for non shared object. rb_ary_modify_check() will be expand as inline function. If it will compile with GCC, Array#<< will be faster around 8%.

2017-05-24Add debug counters.ko1
* debug_counter.h: add the following counters to measure object types. obj_free: freed count obj_str_ptr: freed count of Strings they have extra buff. obj_str_embed: freed count of Strings they don't have extra buff. obj_str_shared: freed count of Strings they have shared extra buff. obj_str_nofree: freed count of Strings they are marked as nofree. obj_str_fstr: freed count of Strings they are marked as fstr. obj_ary_ptr: freed count of Arrays they have extra buff. obj_ary_embed: freed count of Arrays they don't have extra buff. obj_obj_ptr: freed count of Objects (T_OBJECT) they have extra buff. obj_obj_embed: freed count of Objects they don't have extra buff. git-svn-id: svn+ssh:// b2dd03c8-39d4-4d8f-98ff-823fe69b080e

Found a part where copy&paste can be eliminated. Reduces vm_exec_core from 26,228 bytes to 26,176 bytes in size on my machine. I believe it does not affect any runtime performance. ---- * array.c (rb_ary_tmp_new_from_values): extend existing rb_ary_new_from_values function so that it can take additional value for klass. * array.c (rb_ary_new_from_values): use the new function. * insns.def (toregexp): ditto. git-svn-id: svn+ssh:// b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2017-04-13array.c: report correct memsize for shared root arraysrhe
For a shared array root, struct RArray::as.heap.aux.capa stores the number of Arrays holding reference to that T_ARRAY instead of the actual heap-allocated capacity. Use ARY_CAPA() macro which handles this appropriately. git-svn-id: svn+ssh:// b2dd03c8-39d4-4d8f-98ff-823fe69b080e
