* Remove obsoleted lldb_yjit.pyTakashi Kokubun2024-01-081-47/+0
| | | | | | | which clearly seems to be written for Ruby 3.1 YJIT that was not rewritten in Rust yet. Since it has been left there as is, I don't think anybody is actively using this script. We could add a new one if we need it again.
* Introduce NODE_FILEyui-knk2024-01-021-0/+2
| | | | | | | | `__FILE__` was managed by `NODE_STR` with `String` object. This commit introduces `NODE_FILE` and `struct rb_parser_string` so that 1. `__FILE__` is detectable from AST Node 2. Reduce dependency ruby object

* YJIT: implement call fuzzer script (#9129)Maxime Chevalier-Boisvert2023-12-112-0/+385
| | | | | | | | | | | | | | | | | | | | | | | * YJIT: implement call fuzzer script Attempt to detect bugs in YJIT call implementation. * Add basic checks for rest, kwrest. Impprove formatting. * Refactor call fuzzer to make it more powerful and maintainable Compute checksum of arguments * Fix checksum computation. Add useless locals as sussged by Alan. * Add some useless if statements * Add arguments of different types * Pass object arguments as well. Force different shapes. * Compute fuzzing time/speed * Make use of block param

* gdb: Fix a command exampleTakashi Kokubun2023-04-011-1/+1
| | | | | It was actually harder to type `cfp + 1`. `cfp 1` also works and is more useful.

| | | | | Somehow my gdb stopped recognizing VM_BLOCK_HANDLER_NONE (macro) today. Just changing it to a safer code.

| | | | | | | | | | They are needed very often but it's hard to remember. I thought it'd be useful to just copy that to /.vscode and edit that. Usage: cp -r misc/.vscode .vscode Don't symlink it because you'd edit it but not want to commit it.
* Ivar copy needs to happen _before_ setting the shapeAaron Patterson2022-11-011-2/+2
| | | | | | | | When we copy instance variables, it is possible for the GC to be kicked off. The GC looks at the shape to determine what slots to mark inside the object. If the shape is set too soon, the GC could think that there are more instance variables on the object than there actually are at that moment.

* This commit implements the Object Shapes technique in CRuby.Jemma Issroff2022-09-281-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
