2022-09-18	r/4908 refactor(tvix/eval): Don't (ab)use PartialEq for Nix equality	Griffin Smith	1	-2/+2
	Using rust's PartialEq trait to implement Nix equality semantics is reasonably fraught with peril, both because the actual laws are different than what nix expects, and (more importantly) because certain things actually require extra context to compare for equality (for example, thunks need to be forced). This converts the manual PartialEq impl for Value (and all its descendants) to a derived PartialEq impl (which requires a lot of extra PartialEq derives on miscellanious other types within the codebase), and converts the previous nix-semantics equality comparison into a new `nix_eq` method. This returns an EvalResult, even though it can't currently return an error, to allow it to fail when eg forcing thunks (which it will do soon). Since the PartialEq impls for Value and NixAttrs are now quite boring, this converts the generated proptests for those into handwritten ones that cover `nix_eq` instead Change-Id: If3da7171f88c22eda5b7a60030d8b00c3b76f672 Reviewed-on: https://cl.tvl.fyi/c/depot/+/6650 Autosubmit: grfn <grfn@gws.fyi> Tested-by: BuildkiteCI Reviewed-by: tazjin <tazjin@tvl.su>

2022-09-11	r/4812 feat(tvix/eval): add Chunk::pop_op method	Vincent Ambo	1	-0/+22
	This is used to drop an already emitted operation from a chunk again and clean up its span tracking. This is required in cases where the compiler has to backtrack.

2022-09-09	r/4775 feat(tvix/eval): implement DisassemblingObserver for compiler	Vincent Ambo	1	-8/+5
	This type implements an observer that is called whenever the compiler emits a chunk (after the toplevel, thunks, or lambdas) and prints the output of the disassembler to its internal writer. This replaces half of the uses of the `disassembler` feature, which has been removed from the Cargo configuration. Note that at this commit runtime tracing is not yet implemented as an observer.

2022-09-07	r/4709 feat(tvix/eval): add data structures for tracking spans in chunks	Vincent Ambo	1	-0/+50
	This adds a new vector to the chunk data structure which tracks spans into a codemap. The compiler will emit this information to the chunk when adding instructions. The internal representation of the spans is slightly optimised to avoid storing duplicate spans, as there are cases where many instructions might be derived from the same span.
