* `Primitive.mandatory_only?` for fast pathKoichi Sasada2021-11-151-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Compare with the C methods, A built-in methods written in Ruby is slower if only mandatory parameters are given because it needs to check the argumens and fill default values for optional and keyword parameters (C methods can check the number of parameters with `argc`, so there are no overhead). Passing mandatory arguments are common (optional arguments are exceptional, in many cases) so it is important to provide the fast path for such common cases. `Primitive.mandatory_only?` is a special builtin function used with `if` expression like that: ```ruby def self.at(time, subsec = false, unit = :microsecond, in: nil) if Primitive.mandatory_only? Primitive.time_s_at1(time) else Primitive.time_s_at(time, subsec, unit, Primitive.arg!(:in)) end end ``` and it makes two ISeq, ``` def self.at(time, subsec = false, unit = :microsecond, in: nil) Primitive.time_s_at(time, subsec, unit, Primitive.arg!(:in)) end def self.at(time) Primitive.time_s_at1(time) end ``` and (2) is pointed by (1). Note that `Primitive.mandatory_only?` should be used only in a condition of an `if` statement and the `if` statement should be equal to the methdo body (you can not put any expression before and after the `if` statement). A method entry with `mandatory_only?` (`Time.at` on the above case) is marked as `iseq_overload`. When the method will be dispatch only with mandatory arguments (`Time.at(0)` for example), make another method entry with ISeq (2) as mandatory only method entry and it will be cached in an inline method cache. The idea is similar discussed in https://bugs.ruby-lang.org/issues/16254 but it only checks mandatory parameters or more, because many cases only mandatory parameters are given. If we find other cases (optional or keyword parameters are used frequently and it hurts performance), we can extend the feature.

* Allow tracing of optimized methodsJeremy Evans2021-08-211-0/+2
| | | | | | | | | | | | | This updates the trace instructions to directly dispatch to opt_send_without_block. So this should cause no slowdown in non-trace mode. To enable the tracing of the optimized methods, RUBY_EVENT_C_CALL and RUBY_EVENT_C_RETURN are added as events to the specialized instructions.

* add #include guard hack卜部昌平2020-04-131-3/+2
| | | | | | | | | | | | | | | | | | | | | | According to MSVC manual (*1), cl.exe can skip including a header file when that: - contains #pragma once, or - starts with #ifndef, or - starts with #if ! defined. GCC has a similar trick (*2), but it acts more stricter (e. g. there must be _no tokens_ outside of #ifndef...#endif). Sun C lacked #pragma once for a looong time. Oracle Developer Studio 12.5 finally implemented it, but we cannot assume such recent version. This changeset modifies header files so that each of them include strictly one #ifndef...#endif. I believe this is the most portable way to trigger compiler optimizations.

| | | Split ruby.h
* VALUE size packed callinfo (ci).Koichi Sasada2020-02-221-9/+0
| | | | | | | | | | | | | | | | | | | | Now, rb_call_info contains how to call the method with tuple of (mid, orig_argc, flags, kwarg). Most of cases, kwarg == NULL and mid+argc+flags only requires 64bits. So this patch packed rb_call_info to VALUE (1 word) on such cases. If we can not represent it in VALUE, then use imemo_callinfo which contains conventional callinfo (rb_callinfo, renamed from rb_call_info). iseq->body->ci_kw_size is removed because all of callinfo is VALUE size (packed ci or a pointer to imemo_callinfo). To access ci information, we need to use these functions: vm_ci_mid(ci), _flag(ci), _argc(ci), _kwarg(ci). struct rb_call_info_kw_arg is renamed to rb_callinfo_kwarg. rb_funcallv_with_cc() and rb_method_basic_definition_p_with_cc() is temporary removed because cd->ci should be marked.
* decouple internal.h headers卜部昌平2019-12-261-0/+2
| | | | | | | | | | | | | | | | | | Saves comitters' daily life by avoid #include-ing everything from internal.h to make each file do so instead. This would significantly speed up incremental builds. We take the following inclusion order in this changeset: 1. "ruby/config.h", where _GNU_SOURCE is defined (must be the very first thing among everything). 2. RUBY_EXTCONF_H if any. 3. Standard C headers, sorted alphabetically. 4. Other system headers, maybe guarded by #ifdef 5. Everything else, sorted alphabetically. Exceptions are those win32-related headers, which tend not be self- containing (headers have inclusion order dependencies).
* vm_args.c (rb_warn_check): Use iseq_unique_id instead of its pointerYusuke Endoh2019-12-091-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | (This is the second try of 036bc1da6c6c9b0fa9b7f5968d897a9554dd770e.) If iseq is GC'ed, the pointer of iseq may be reused, which may hide a deprecation warning of keyword argument change. http://ci.rvm.jp/results/trunk-test1@phosphorus-docker/2474221 ``` 1) Failure: TestKeywordArguments#test_explicit_super_kwsplat [/tmp/ruby/v2/src/trunk-test1/test/ruby/test_keyword.rb:549]: --- expected +++ actual @@ -1 +1 @@ -/The keyword argument is passed as the last hash parameter.* for `m'/m +"" ``` This change ad-hocly adds iseq_unique_id for each iseq, and use it instead of iseq pointer. This covers the case where caller is GC'ed. Still, the case where callee is GC'ed, is not covered. But anyway, it is very rare that iseq is GC'ed. Even when it occurs, it just hides some warnings. It's no big deal.
* make functions static卜部昌平2019-11-191-2/+0
| | | | | | | These functions are used from within a compilation unit so we can make them static, for better binary size. This changeset reduces the size of generated ruby binary from 26,590,128 bytes to 26,584,472 bytes on my macihne.
* delete unused functions卜部昌平2019-11-141-2/+0
| | | | | | | | | | | | Looking at the list of symbols inside of libruby-static.a, I found hundreds of functions that are defined, but used from nowhere. There can be reasons for each of them (e.g. some functions are specific to some platform, some are useful when debugging, etc). However it seems the functions deleted here exist for no reason. This changeset reduces the size of ruby binary from 26,671,456 bytes to 26,592,864 bytes on my machine.
* Avoid top-level search for nested constant reference from nil in defined?Dylan Thacker-Smith2019-11-131-1/+2
| | | | | | | | | | | | Fixes [Bug #16332] Constant access was changed to no longer allow top-level constant access through `nil`, but `defined?` wasn't changed at the same time to stay consistent. Use a separate defined type to distinguish between a constant referenced from the current lexical scope and one referenced from another namespace.

* support builtin features with Ruby and C.Koichi Sasada2019-11-081-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Support loading builtin features written in Ruby, which implement with C builtin functions. [Feature #16254] Several features: (1) Load .rb file at boottime with native binary. Now, prelude.rb is loaded at boottime. However, this file is contained into the interpreter as a text format and we need to compile it. This patch contains a feature to load from binary format. (2) __builtin_func() in Ruby call func() written in C. In Ruby file, we can write `__builtin_func()` like method call. However this is not a method call, but special syntax to call a function `func()` written in C. C functions should be defined in a file (same compile unit) which load this .rb file. Functions (`func` in above example) should be defined with (a) 1st parameter: rb_execution_context_t *ec (b) rest parameters (0 to 15). (c) VALUE return type. This is very similar requirements for functions used by rb_define_method(), however `rb_execution_context_t *ec` is new requirement. (3) automatic C code generation from .rb files. tool/mk_builtin_loader.rb creates a C code to load .rb files needed by miniruby and ruby command. This script is run by BASERUBY, so *.rb should be written in BASERUBY compatbile syntax. This script load a .rb file and find all of __builtin_ prefix method calls, and generate a part of C code to export functions. tool/mk_builtin_binary.rb creates a C code which contains binary compiled Ruby files needed by ruby command.
* avoid overflow in integer multiplication卜部昌平2019-10-091-2/+4
| | | | | | | This changeset basically replaces `ruby_xmalloc(x * y)` into `ruby_xmalloc2(x, y)`. Some convenient functions are also provided for instance `rb_xmalloc_mul_add(x, y, z)` which allocates x * y + z byes.
* Remove mark arrayAaron Patterson2019-09-261-1/+0

* Scan the ISEQ arena for markables and mark themAaron Patterson2019-09-261-0/+1
| | | | | This commit scans the ISEQ arena for objects that can be marked and marks them. This should make the mark array unnecessary.
* Introduce a secondary arenaAaron Patterson2019-09-261-2/+8
| | | | | | We'll scan the secondary arena during GC mark. So, we should only allocate "markable" instruction linked list nodes out of the secondary arena.
* Unify SUPPORT_JOKE and OPT_SUPPORT_JOKETakashi Kokubun2019-09-031-1/+1
| | | | | | | | | | for simplicity and consistency. Now SUPPORT_JOKE needs to be prefixed with OPT_ to make the config visible in `RubyVM::VmOptsH`, and the inconsistency was introduced. As it has never been available for override in configure (no #ifndef guard), it should be fine to rename the config.
* decouple compile.c usage of imemo_ifunc卜部昌平2019-08-271-1/+1
| | | | | | | After 5e86b005c0f2ef30df2f9906c7e2f3abefe286a2, I now think ANYARGS is dangerous and should be extinct. This commit deletes ANYARGS from struct vm_ifunc, but in doing so we also have to decouple the usage of this struct in compile.c, which (I think) is an abuse of ANYARGS.

Enabled tragetting TracePoints can not enabled again with and without target. * vm_core.h (rb_iseq_t): introduce `rb_iseq_t::local_hooks` to store local hooks. `rb_iseq_t::aux::trace_events` is renamed to `global_trace_events` to contrast with `local_hooks`. * vm_core.h (rb_hook_list_t): add `rb_hook_list_t::running` to represent how many Threads/Fibers are used this list. If this field is 0, nobody using this hooks and we can delete it. This is why we can remove code from cont.c. * vm_core.h (rb_vm_t): because of above change, we can eliminate `rb_vm_t::trace_running` field.
