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.

2022-09-09	r/4773 refactor(tvix/eval): index into Chunk with ConstantIdx/CodeIdx	Vincent Ambo	1	-4/+18
	This is a step towards hiding the internal fields of thunk, and making the interface of the type more predictable. Part of the preparation for implementing observers.

2022-09-08	r/4767 fix(tvix/eval): ensure disassembler prints continous lines correctly	Vincent Ambo	1	-0/+9
	There can be different spans on the same line, so the previous implementation would duplicate line numbers unnecessarily. Change-Id: I8d8db77177aee0d834a6ec3584641e1bd5f31c3e Reviewed-on: https://cl.tvl.fyi/c/depot/+/6434 Reviewed-by: sterni <sternenseemann@systemli.org> Tested-by: BuildkiteCI

	If the disassembler feature is enabled, make sure that an Rc of the codemap is available through the chunk. Change-Id: I700f27ab665a704f73457b19bd2d7efc93828a16 Reviewed-on: https://cl.tvl.fyi/c/depot/+/6414 Reviewed-by: sterni <sternenseemann@systemli.org> Tested-by: BuildkiteCI

	These are not actually used yet; this is in preparation for a multi-commit chain for emitting all the right spans in the right locations.

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.

2022-09-01	r/4576 refactor(tvix/eval): return a lambda from the compiler	Vincent Ambo	1	-1/+1
	Changes the internal compiler plumbing to not just return a chunk of code, but the same chunk wrapped inside of a lambda value. This is one more step towards compiling runtime lambdas.

	This makes for a much nicer view of an execution if `--feature disassembler` is set, for example: tvix-repl> let value = [ 1 2 { a = 1; } ]; in value ++ [ 1 ] === compiled bytecode (11 operations) === 02 OpConstant(1) 02 OpConstant(2) 02 OpConstant("a") 02 OpConstant(1) 02 OpAttrs(1) 02 OpList(3) 02 OpGetLocal(0) 02 OpConstant(1) 02 OpList(1) 02 OpConcat 02 OpCloseScope(1) === runtime trace === 0001 OpConstant(ConstantIdx(0)) [ 1 ] 0002 OpConstant(ConstantIdx(1)) [ 1 2 ] 0003 OpConstant(ConstantIdx(2)) [ 1 2 "a" ] 0004 OpConstant(ConstantIdx(3)) [ 1 2 "a" 1 ] 0005 OpAttrs(1) [ 1 2 { a = 1; } ] 0006 OpList(3) [ [ 1 2 { a = 1; } ] ] 0007 OpGetLocal(0) [ [ 1 2 { a = 1; } ] [ 1 2 { a = 1; } ] ] 0008 OpConstant(ConstantIdx(4)) [ [ 1 2 { a = 1; } ] [ 1 2 { a = 1; } ] 1 ] 0009 OpList(1) [ [ 1 2 { a = 1; } ] [ 1 2 { a = 1; } ] [ 1 ] ] 0010 OpConcat [ [ 1 2 { a = 1; } ] [ 1 2 { a = 1; } 1 ] ] 0011 OpCloseScope(1) [ [ 1 2 { a = 1; } 1 ] ] => [ 1 2 { a = 1; } 1 ] :: list Change-Id: If79c7fd1f0f18255ddb3763c1ba585fda8041b1b Reviewed-on: https://cl.tvl.fyi/c/depot/+/6195 Tested-by: BuildkiteCI Reviewed-by: sterni <sternenseemann@systemli.org>
