* hash.c: cast from double to unsigned is undefinedshyouhei2018-11-151-1/+3
| | | | | | | | | | | | | | | | | | | | When a negative double is casted into an unsigned type, that operation is undefined (cf: ISO/IEC 9899:1990 section 6.2.9.3). Recent versions of C kindly footnotes that "The remaindering operation performed when a value of integer type is converted to unsigned type need not be performed when a value of real floating type is converted to unsigned type" (cf: ISO/IEC 9899:1999 section 6.3.1.4 footnote 50). So it is a wrong idea to just cast a double to st_data_t. The intention of the code is commented as "mix the actual float value in". It seems we should do a reinterpret_cast and rule out static_cast. Confirmed this changeset does not affect `make benchmark`. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@65737 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* hash.c: +(-1) is a wrong ideashyouhei2018-11-081-1/+5
| | | | | | | | | | | | | Before this changeset RHASH_ARRAY_SIZE_DEC() was expaneded to include an expression like `RHASH_ARRAY_SIZE+(-1)`. RHASH_ARRAY_SIZE is by definition unsigned int. -1 is signed, of course. Adding a signed and an unsigned value requires the "usual arithmetic conversions" (cf: ISO/IEC 9899:1990 section 6.2.1.5). -1 is converted to 0xFFFF by that. This patch prevents that conversion. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@65632 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

| | | | | | | | | | | | Both methods Hash#length and Hash#size share the same source code in Ruby, but they also share the same documentation. Now when you look at the documentation of Hash#size you only see examples for Hash#length, which is confusing. This commit includes Hash#size in the examples and also remarks that both methods are equivalent to each other.

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.

| | | | | | | | | * hash.c (mult_and_mix): use uint128_t instead of __uint128_t. [ruby-core:84438] [Bug #14231] From: Nobuyoshi Nakada <nobu@ruby-lang.org> git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61472 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* Use UINT128_T support flag from configurenobu2017-12-251-1/+1
| | | | | | | | | | | | | | | | | Current check for __uint128_t in hash.c is not valid, since it ignores compilers other than gcc. We hit this on lcc on e2k platform. Configure script properly checks from 128-bit data types support and sets HAVE_UINT128_T accordingly. This approach is already used within ruby at bignum.c, random.c, etc. Probably hash.c is an overlooked remnant of old days. This patch fixes this.

* Revamp method coverage to support define_methodmame2017-12-051-0/+8
| | | | | | | | | | | | | | Traditionally, method coverage measurement was implemented by inserting `trace2` instruction to the head of method iseq. So, it just measured methods defined by `def` keyword. This commit drastically changes the measuring mechanism of method coverage; at `RUBY_EVENT_CALL`, it keeps a hash from rb_method_entry_t* to runs (i.e., it counts the runs per method entry), and at `Coverage.result`, it creates the result hash by enumerating all `rb_method_entry_t*` objects (by `ObjectSpace.each_object`). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61023 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
