2022-09-06 r/4656 feat(tvix/eval): allow ignoring locals by prefixing with _Vincent Ambo1-1/+2
This is a common idiom in both Nix and other languages when a local is declared without actually being used. Since Tvix warns for unused locals, having this available is useful and can be included in the final error message as a suggestion if an unused variable is intentional.

The `With` struct no longer contained any internals after the cleanup logic for the stack had been moved into Compiler::compile_with, leaving the `Vec<With>` to essentially act as a counter for the number of things on the with stack. That's inefficient of course, so with this commit it actually becomes an integer (with an encapsulated API within scope::Scope).

2022-09-04 r/4639 fix(tvix/eval): open/close additional scope around `with`Vincent Ambo1-0/+2
This is required to correctly clean up the `with` values. At the moment, the attrset from which identifiers are being taken is always pushed on the stack. This means that it must also be removed again, otherwise in an expression like with { a = 15; }; a The final stack is `[ { a = 15; } 15 ]` *after the last operation*, which means that the attrset is still on there as garbage. This has little practical impact right now because it is always shadowed by the fact that the actual expression value is at the right location, but becomes relevant when accounting for upvalue captures.

These cases are not yet handled specially, and the logic of when things are marked initialised (which was previously always at the same spot as their declaration) has not changed, making this commit a runtime no-op for now.

2022-09-03 r/4629 feat(tvix/eval): implement runtime closure construction (OpClosure)Vincent Ambo1-1/+28
Implements the final bit of logic remaining for wiring up closures, which is the runtime construction of closure objects. When encountering an OpClosure, the VM walks through the bytecode collecting all the upvalue location operands (see commit introducing the OpCode::Data* variants for details) and stores the runtime values in the new closures upvalue vector. After that, the handling of the closure itself becomes functionally identical to that of lambdas. With this initial implementation of closures there are several large optimisation potentials available, the two most notable ones are: - Distinguish the runtime representation of lambdas and closures explicitly. - Detect and handle multiple-arity functions directly in the compiler. However, for both of these we should wait until we have appropriate benchmarking infrastructure in place. This is because our test implementations have shown that the complexity of either of these changes is quite significant, and we do not yet know if they really pay off.

2022-09-03 r/4625 feat(tvix/eval): compile creation of closure objectsVincent Ambo4-6/+51
Fully implements the instructions for compiling closure objects (without runtime handling yet). Closure (and thunk) objects are created at runtime by capturing all known upvalues. To represent this, the instructions for creating them need to have a variable number of arguments. Due to that, this commit introduces new variants in OpCode that are not actually operations, but data. If the VM is implemented correctly, the instruction pointer should never point at these. Due to this, the VM will panic if it sees a data operand during an execution run.

Refactors the update function to take the attribute sets by value instead. To facilitate this, we use an equivalent of the currently unstable `Rc::clone_or_unwrap` in the VM when encountering attribute sets, so that in cases where the only references to the attrs being updated are the ones on the stack those clones are avoided completely. This does make update() a little bit more tricky internally, as some optimised branches can directly return the moved value, and others need to destructure with ownership. For this reason there are now two different match statements handling the different ownership cases.
