2025-01-08Pass allocation size to rb_imemo_newPeter Zhu
This would allow imemo to take advantage of VWA and allocate sizes larger than RVALUE (40 bytes). Notes: Merged: https://github.com/ruby/ruby/pull/12524
2025-01-07Remove IMEMO_DEBUGPeter Zhu
The code path hasn't compiled for almost a year, since 330830dd1a44b6e497250a14d93efae6fa363f82, so probably nobody uses it. Notes: Merged: https://github.com/ruby/ruby/pull/12519
2024-10-11Remove 1 allocation in Enumerable#each_with_index (#11868)Alan Wu
* Remove 1 allocation in Enumerable#each_with_index Previously, each call to Enumerable#each_with_index allocates 2 objects, one for the counting index, the other an imemo_ifunc passed to `self.each` as a block. Use `struct vm_ifunc::data` to hold the counting index directly to remove 1 allocation. * [DOC] Brief summary for usages of `struct vm_ifunc` Notes: Merged-By: maximecb <[email protected]>
2024-07-10Add rb_block_call2, a flexible variant of rb_block_callYusuke Endoh
This function accepts flags: RB_NO_KEYWORDS, RB_PASS_KEYWORDS, RB_PASS_CALLED_KEYWORDS: Works as the same as rb_block_call_kw. RB_BLOCK_NO_USE_PACKED_ARGS: The given block ("bl_proc") does not use "yielded_arg" of rb_block_call_func_t. Instead, the block accesses the yielded arguments via "argc" and "argv". This flag allows the called method to yield arguments without allocating an Array.
2024-04-26[Universal parser] Decouple IMEMO from rb_ast_tHASUMI Hitoshi
This patch removes the `VALUE flags` member from the `rb_ast_t` structure making `rb_ast_t` no longer an IMEMO object. ## Background We are trying to make the Ruby parser generated from parse.y a universal parser that can be used by other implementations such as mruby. To achieve this, it is necessary to exclude VALUE and IMEMO from parse.y, AST, and NODE. ## Summary (file by file) - `rubyparser.h` - Remove the `VALUE flags` member from `rb_ast_t` - `ruby_parser.c` and `internal/ruby_parser.h` - Use TypedData_Make_Struct VALUE which wraps `rb_ast_t` `in ast_alloc()` so that GC can manage it - You can retrieve `rb_ast_t` from the VALUE by `rb_ruby_ast_data_get()` - Change the return type of `rb_parser_compile_XXXX()` functions from `rb_ast_t *` to `VALUE` - rb_ruby_ast_new() which internally `calls ast_alloc()` is to create VALUE vast outside ruby_parser.c - `iseq.c` and `vm_core.h` - Amend the first parameter of `rb_iseq_new_XXXX()` functions from `rb_ast_body_t *` to `VALUE` - This keeps the VALUE of AST on the machine stack to prevent being removed by GC - `ast.c` - Almost all change is replacement `rb_ast_t *ast` with `VALUE vast` (sorry for the big diff) - Fix `node_memsize()` - Now it includes `rb_ast_local_table_link`, `tokens` and script_lines - `compile.c`, `load.c`, `node.c`, `parse.y`, `proc.c`, `ruby.c`, `template/prelude.c.tmpl`, `vm.c` and `vm_eval.c` - Follow-up due to the above changes - `imemo.{c|h}` - If an object with `imemo_ast` appears, considers it a bug Co-authored-by: Nobuyoshi Nakada <[email protected]>
2024-02-22Extract imemo functions from gc.c into imemo.cPeter Zhu
2024-02-21Add IMEMO_NEWPeter Zhu
Rather than exposing that an imemo has a flag and four fields, this changes the implementation to only expose one field (the klass) and fills the rest with 0. The type will have to fill in the values themselves.
2024-02-20[Feature #20257] Rearchitect Ripperyui-knk
Introduce another semantic value stack for Ripper so that Ripper can manage both Node and Ruby Object separately. This rearchitectutre of Ripper solves these issues. Therefore adding test cases for them. * [Bug 10436] https://bugs.ruby-lang.org/issues/10436 * [Bug 18988] https://bugs.ruby-lang.org/issues/18988 * [Bug 20055] https://bugs.ruby-lang.org/issues/20055 Checked the differences of `Ripper.sexp` for files under `/test/ruby` are only on test_pattern_matching.rb. The differences comes from the differences between `new_hash_pattern_tail` functions between parser and Ripper. Ripper `new_hash_pattern_tail` didn’t call `assignable` then `kw_rest_arg` wasn’t marked as local variable.

The macro SafeStringValue() became just StringValue() in c5c05460ac2, and it is deprecated nowadays. This patch replaces remaining macro usage. Some occurrences are left in ext/stringio and ext/win32ole, they should be fixed upstream. The macro itself is not deleted, because it may be used in extensions.

2022-09-26Revert this until we can figure out WB issues or remove shapes from GCAaron Patterson
Revert "* expand tabs. [ci skip]" This reverts commit 830b5b5c351c5c6efa5ad461ae4ec5085e5f0275. Revert "This commit implements the Object Shapes technique in CRuby." This reverts commit 9ddfd2ca004d1952be79cf1b84c52c79a55978f4.
2022-09-26This commit implements the Object Shapes technique in CRuby.Jemma Issroff
Object Shapes is used for accessing instance variables and representing the "frozenness" of objects. Object instances have a "shape" and the shape represents some attributes of the object (currently which instance variables are set and the "frozenness"). Shapes form a tree data structure, and when a new instance variable is set on an object, that object "transitions" to a new shape in the shape tree. Each shape has an ID that is used for caching. The shape structure is independent of class, so objects of different types can have the same shape. For example: ```ruby class Foo def initialize # Starts with shape id 0 @a = 1 # transitions to shape id 1 @b = 1 # transitions to shape id 2 end end class Bar def initialize # Starts with shape id 0 @a = 1 # transitions to shape id 1 @b = 1 # transitions to shape id 2 end end foo = Foo.new # `foo` has shape id 2 bar = Bar.new # `bar` has shape id 2 ``` Both `foo` and `bar` instances have the same shape because they both set instance variables of the same name in the same order. This technique can help to improve inline cache hits as well as generate more efficient machine code in JIT compilers. This commit also adds some methods for debugging shapes on objects. See `RubyVM::Shape` for more details. For more context on Object Shapes, see [Feature: #18776] Co-Authored-By: Aaron Patterson <[email protected]> Co-Authored-By: Eileen M.

2021-04-26node.c (rb_ast_new): imemo_ast is WB-unprotectedYusuke Endoh
Previously imemo_ast was handled as WB-protected which caused a segfault of the following code: # shareable_constant_value: literal M0 = {} M1 = {} ... M100000 = {} My analysis is here: `shareable_constant_value: literal` creates many Hash instances during parsing, and add them to node_buffer of imemo_ast. However, the contents are missed because imemo_ast is incorrectly WB-protected. This changeset makes imemo_ast as WB-unprotected.

2021-01-05enable constant cache on ractorsKoichi Sasada
constant cache `IC` is accessed by non-atomic manner and there are thread-safety issues, so Ruby 3.0 disables to use const cache on non-main ractors. This patch enables it by introducing `imemo_constcache` and allocates it by every re-fill of const cache like `imemo_callcache`. [Bug #17510] Now `IC` only has one entry `IC::entry` and it points to `iseq_inline_constant_cache_entry`, managed by T_IMEMO object. `IC` is atomic data structure so `rb_mjit_before_vm_ic_update()` and `rb_mjit_after_vm_ic_update()` is not needed.

2020-04-13add #include guard hack卜部昌平
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.

2020-02-22Introduce disposable call-cache.Koichi Sasada
This patch contains several ideas: (1) Disposable inline method cache (IMC) for race-free inline method cache * Making call-cache (CC) as a RVALUE (GC target object) and allocate new CC on cache miss. * This technique allows race-free access from parallel processing elements like RCU. (2) Introduce per-Class method cache (pCMC) * Instead of fixed-size global method cache (GMC), pCMC allows flexible cache size. * Caching CCs reduces CC allocation and allow sharing CC's fast-path between same call-info (CI) call-sites. (3) Invalidate an inline method cache by invalidating corresponding method entries (MEs) * Instead of using class serials, we set "invalidated" flag for method entry itself to represent cache invalidation. * Compare with using class serials, the impact of method modification (add/overwrite/delete) is small. * Updating class serials invalidate all method caches of the class and sub-classes. * Proposed approach only invalidate the method cache of only one ME. See [Feature #16614] for more details. Notes: Merged: https://github.com/ruby/ruby/pull/2888
2020-02-22VALUE size packed callinfo (ci).Koichi Sasada
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.

One day, I could not resist the way it was written. I finally started to make the code clean. This changeset is the beginning of a series of housekeeping commits. It is a simple refactoring; split internal.h into files, so that we can divide and concur in the upcoming commits. No lines of codes are either added or removed, except the obvious file headers/footers. The generated binary is identical to the one before.
