2018-11-09numeric.c: avoid division by zeroshyouhei
In C, division by zero is undefined, even if the expression is double (cf: ISO/IEC 9899:1990 section 6.3.5). OTOH we have tests about such operations and results, means we expect no exceptional situation shall occur. We need to carefully reroute the situation, and generate what is needed. See also: https://travis-ci.org/ruby/ruby/jobs/452680646#L2943 PS: Recently (last two decades), C have Annex. F document. It normatively specifies that the division operator is IEEE 754's division operator (cf: ISO/IEC 9899:1999 section F.3). If we could move to such newer version this could be no problem. But that is not possible today. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@65642 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2018-08-06enumerator.c: Introduce Enumerator::ArithmeticSequencemrkn
This commit introduces new core class Enumerator::ArithmeticSequence. Enumerator::ArithmeticSequence is a subclass of Enumerator, and represents a number generator of an arithmetic sequence. After this commit, Numeric#step and Range#step without blocks returned an ArithmeticSequence object instead of an Enumerator. This class introduces the following incompatibilities: - You can create a zero-step ArithmeticSequence, and its size is not ArgumentError, but Infinity. - You can create a negative-step ArithmeticSequence from a range.

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.

This commit is based on the pull-request #1320 created by Makoto Kishimoto. [Feature #12508] [Feature #11003] [close GH-1320] * bignum.c (rb_int_powm): Added for Integer#pow(b, m). * internal.h (rb_int_powm): Declared to refer in numeric.c. * bignum.c (bary_powm_gmp): Added for Integer#pow(b, m) using GMP. * bignum.c (int_pow_tmp1): Added for implementing Integer#pow(b, m). * bignum.c (int_pow_tmp2, int_pow_tmp3): ditto. * internal.h (rb_num_positive_int_p): Moved from numeric.c for sharing the definition with bignum.c. * internal.h (rb_num_negative_int_p, rb_num_compare_with_zero): ditto. * numeric.c(negative_int_p): Moved to internal.h for sharing the definition with bignum.c. * numeric.c (positive_int_p, compare_with_zero): ditto. * numeric.c (rb_int_odd_p): Exported (renamed from int_odd_p). * internal.h (rb_int_odd_p): ditto. * internal.h (HALF_LONG_MSB): Added. * numeric.c (SQRT_LONG_MAX): Redefined by using HALF_LONG_MSB. * test/ruby/test_numeric.rb (test_pow): Added for Integer#pow(b, m). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61003 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
