* Move `catch_except_p` to `compile_data`eileencodes2023-04-111-0/+1
| | | | | | | | | | | | | | The `catch_except_p` flag is used for communicating between parent and child iseq's that a throw instruction was emitted. So for example if a child iseq has a throw in it and the parent wants to catch the throw, we use this flag to communicate to the parent iseq that a throw instruction was emitted. This flag is only useful at compile time, it only impacts the compilation process so it seems to be fine to move it from the iseq body to the compile_data struct.

* New constant caching insn: opt_getconstant_pathJohn Hawthorn2022-09-011-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously YARV bytecode implemented constant caching by having a pair of instructions, opt_getinlinecache and opt_setinlinecache, wrapping a series of getconstant calls (with putobject providing supporting arguments). This commit replaces that pattern with a new instruction, opt_getconstant_path, handling both getting/setting the inline cache and fetching the constant on a cache miss. This is implemented by storing the full constant path as a null-terminated array of IDs inside of the IC structure. idNULL is used to signal an absolute constant reference. $ ./miniruby --dump=insns -e '::Foo::Bar::Baz' == disasm: #<ISeq:<main>@-e:1 (1,0)-(1,13)> (catch: FALSE) 0000 opt_getconstant_path <ic:0 ::Foo::Bar::Baz> ( 1)[Li] 0002 leave The motivation for this is that we had increasingly found the need to disassemble the instructions between the opt_getinlinecache and opt_setinlinecache in order to determine the constant we are fetching, or otherwise store metadata. This disassembly was done: * In opt_setinlinecache, to register the IC against the constant names it is using for granular invalidation. * In rb_iseq_free, to unregister the IC from the invalidation table. * In YJIT to find the position of a opt_getinlinecache instruction to invalidate it when the cache is populated * In YJIT to register the constant names being used for invalidation. With this change we no longe need disassemly for these (in fact rb_iseq_each is now unused), as the list of constant names being referenced is held in the IC. This should also make it possible to make more optimizations in the future. This may also reduce the size of iseqs, as previously each segment required 32 bytes (on 64-bit platforms) for each constant segment. This implementation only stores one ID per-segment. There should be no significant performance change between this and the previous implementation. Previously opt_getinlinecache was a "leaf" instruction, but it included a jump (almost always to a separate cache line). Now opt_getconstant_path is a non-leaf (it may raise/autoload/call const_missing) but it does not jump. These seem to even out.

* Fix ISeq dump / load in array casesAaron Patterson2022-06-291-0/+1
| | | | | | | | | | | We need to dump relative offsets for inline storage entries so that loading iseqs as an array works as well. This commit also has some minor refactoring to make computing relative ISE information easier. This should fix the iseq dump / load as array tests we're seeing fail in CI.

* Speed up ISeq by marking via bitmaps and IC rearrangingAaron Patterson2022-06-231-0/+6
| | | | | | | | | | | | | | | | This commit adds a bitfield to the iseq body that stores offsets inside the iseq buffer that contain values we need to mark. We can use this bitfield to mark objects instead of disassembling the instructions. This commit also groups inline storage entries and adds a counter for each entry. This allows us to iterate and mark each entry without disassembling instructions Since we have a bitfield and grouped inline caches, we can mark all VALUE objects associated with instructions without actually disassembling the instructions at mark time.

* Finer-grained constant cache invalidation (take 2)Kevin Newton2022-04-011-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | This commit reintroduces finer-grained constant cache invalidation. After 8008fb7 got merged, it was causing issues on token-threaded builds (such as on Windows). The issue was that when you're iterating through instruction sequences and using the translator functions to get back the instruction structs, you're either using `rb_vm_insn_null_translator` or `rb_vm_insn_addr2insn2` depending if it's a direct-threading build. `rb_vm_insn_addr2insn2` does some normalization to always return to you the non-trace version of whatever instruction you're looking at. `rb_vm_insn_null_translator` does not do that normalization. This means that when you're looping through the instructions if you're trying to do an opcode comparison, it can change depending on the type of threading that you're using. This can be very confusing. So, this commit creates a new translator function `rb_vm_insn_normalizing_translator` to always return the non-trace version so that opcode comparisons don't have to worry about different configurations.

* Finer-grained inline constant cache invalidationKevin Newton2022-03-241-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current behavior - caches depend on a global counter. All constant mutations cause caches to be invalidated. ```ruby class A B = 1 end def foo A::B # inline cache depends on global counter end foo # populate inline cache foo # hit inline cache C = 1 # global counter increments, all caches are invalidated foo # misses inline cache due to `C = 1` ``` Proposed behavior - caches depend on name components. Only constant mutations with corresponding names will invalidate the cache. ```ruby class A B = 1 end def foo A::B # inline cache depends constants named "A" and "B" end foo # populate inline cache foo # hit inline cache C = 1 # caches that depend on the name "C" are invalidated foo # hits inline cache because IC only depends on "A" and "B" ``` Examples of breaking the new cache: ```ruby module C # Breaks `foo` cache because "A" constant is set and the cache in foo depends # on "A" and "B" class A; end end B = 1 ``` We expect the new cache scheme to be invalidated less often because names aren't frequently reused. With the cache being invalidated less, we can rely on its stability more to keep our constant references fast and reduce the need to throw away generated code in YJIT.
* Add ISEQ_BODY macroPeter Zhu2022-03-241-11/+11

* Rework tracing for blocks running as methodsAlan Wu2021-12-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The main impetus for this change is to fix [Bug #13392]. Previously, we fired the "return" TracePoint event after popping the stack frame for the block running as method (BMETHOD). This gave undesirable source location outputs as the return event normally fires right before the frame going away. The iseq for each block can run both as a block and as a method. To accommodate that, this commit makes vm_trace() fire call/return events for instructions that have b_call/b_return events attached when the iseq is running as a BMETHOD. The logic for rewriting to "trace_*" instruction is tweaked so that when the user listens to call/return events, instructions with b_call/b_return become trace variants. To continue to provide the return value for non-local returns done using the "return" or "break" keyword inside BMETHODs, the stack unwinding code is tweaked. b_return events now provide the same return value as return events for these non-local cases. A pre-existing test deemed not providing a return value for these b_return events as a limitation. This commit removes the checks for call/return TracePoint events that happen when calling into BMETHODs when no TracePoints are active. Technically, migrating just the return event is enough to fix the bug, but migrating both call and return removes our reliance on `VM_FRAME_FLAG_FINISH` and re-entering the interpreter when the caller is already in the interpreter.
* `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.

| | | | | | | | | | | | | 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.

* 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.

| | | | | | | | | | | | Looking at the list of symbols inside of libruby-static.a, I found hundreds of functions that are defined, but used from nowhere.

* 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
