2021-08-13Revert "Pause an MJIT worker when JIT is cancelled"Takashi Kokubun
This reverts commit b64f81c81729bbc248d19af01cafde88eb60fdc7. It seems to cause a problem in --jit / --jit-wait CIs. Reverting for now.

2021-07-15Add pattern matching pin support for instance/class/global variablesJeremy Evans
Pin matching for local variables and constants is already supported, and it is fairly simple to add support for these variable types. Note that pin matching for method calls is still not supported without wrapping in parentheses (pin expressions). I think that's for the best as method calls are far more complex (arguments/blocks).

2021-04-21Evaluate multiple assignment left hand side before right hand sideJeremy Evans
In regular assignment, Ruby evaluates the left hand side before the right hand side. For example: ```ruby foo[0] = bar ``` Calls `foo`, then `bar`, then `[]=` on the result of `foo`. Previously, multiple assignment didn't work this way. If you did: ```ruby abc.def, foo[0] = bar, baz ``` Ruby would previously call `bar`, then `baz`, then `abc`, then `def=` on the result of `abc`, then `foo`, then `[]=` on the result of `foo`. This change makes multiple assignment similar to single assignment, changing the evaluation order of the above multiple assignment code to calling `abc`, then `foo`, then `bar`, then `baz`, then `def=` on the result of `abc`, then `[]=` on the result of `foo`. Implementing this is challenging with the stack-based virtual machine. We need to keep track of all of the left hand side attribute setter receivers and setter arguments, and then keep track of the stack level while handling the assignment processing, so we can issue the appropriate topn instructions to get the receiver. Here's an example of how the multiple assignment is executed, showing the stack and instructions: ``` self # putself abc # send abc, self # putself abc, foo # send abc, foo, 0 # putobject 0 abc, foo, 0, [bar, baz] # evaluate RHS abc, foo, 0, [bar, baz], baz, bar # expandarray abc, foo, 0, [bar, baz], baz, bar, abc # topn 5 abc, foo, 0, [bar, baz], baz, abc, bar # swap abc, foo, 0, [bar, baz], baz, def= # send abc, foo, 0, [bar, baz], baz # pop abc, foo, 0, [bar, baz], baz, foo # topn 3 abc, foo, 0, [bar, baz], baz, foo, 0 # topn 3 abc, foo, 0, [bar, baz], baz, foo, 0, baz # topn 2 abc, foo, 0, [bar, baz], baz, []= # send abc, foo, 0, [bar, baz], baz # pop abc, foo, 0, [bar, baz] # pop [bar, baz], foo, 0, [bar, baz] # setn 3 [bar, baz], foo, 0 # pop [bar, baz], foo # pop [bar, baz] # pop ``` As multiple assignment must deal with splats, post args, and any level of nesting, it gets quite a bit more complex than this in non-trivial cases. To handle this, struct masgn_state is added to keep track of the overall state of the mass assignment, which stores a linked list of struct masgn_attrasgn, one for each assigned attribute. This adds a new optimization that replaces a topn 1/pop instruction combination with a single swap instruction for multiple assignment to non-aref attributes. This new approach isn't compatible with one of the optimizations previously used, in the case where the multiple assignment return value was not needed, there was no lhs splat, and one of the left hand side used an attribute setter. This removes that optimization. Removing the optimization allowed for removing the POP_ELEMENT and adjust_stack functions. This adds a benchmark to measure how much slower multiple assignment is with the correct evaluation order. This benchmark shows: * 4-9% decrease for attribute sets * 14-23% decrease for array member sets * Basically same speed for local variable sets Importantly, it shows no significant difference between the popped (where return value of the multiple assignment is not needed) and !popped (where return value of the multiple assignment is needed) cases for attribute and array member sets. This indicates the previous optimization, which was dropped in the evaluation order fix and only affected the popped case, is not important to performance.

2021-01-14Make Module#prepend affect ancestor chain even if argument already included ↵Jeremy Evans
in receiver Previously, if a class included a module and then prepended the same module, the prepend had no effect. This changes the behavior so that the prepend has an effect unless the module is already prepended the receiver. While here, rename the origin_seen variable in include_modules_at, since it is misleading. The variable tracks whether c has been seen, not whether the origin of klass has been.

2021-01-13Rename RubyVM::MJIT to RubyVM::JITTakashi Kokubun
because the name "MJIT" is an internal code name, it's inconsistent with --jit while they are related to each other, and I want to discourage future JIT implementation-specific (e.g. MJIT-specific) APIs by this rename. [Feature #17490]
