2022-09-09	r/4775 feat(tvix/eval): implement DisassemblingObserver for compiler	Vincent Ambo	1	-28/+16
	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.

2022-09-08	r/4768 feat(tvix/eval): print lambda memory adresses in disassembler	Vincent Ambo	1	-10/+11
	This makes it easier to track exactly which lambda is which when inspecting e.g. the concrete representation of a thunk. At runtime all lambdas live in an Rc. To make this print the right address, the construction of these Rcs had to be moved up right to the point where the lambda is first emitted (and disassembled).

2022-09-08	r/4767 fix(tvix/eval): ensure disassembler prints continous lines correctly	Vincent Ambo	1	-4/+3
	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

2022-09-08	r/4752 refactor(tvix/eval): implement much clearer disassembler output	Vincent Ambo	1	-3/+5
	With this change the runtime trace contains much more exact information about the context of the computation (entering/exiting calls etc.) This is in large part due to moving the tracer to be a field on the VM itself, which enables consistent ordering of traces across the execution, and tracing an execution with its input instead of output stack.

2022-08-30	r/4534 feat(tvix/eval): implement chunk disassembler output	Vincent Ambo	1	-0/+31
	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>
2022-08-30	r/4533 feat(tvix/eval): implement optional runtime tracing	Vincent Ambo	1	-0/+37
	This adds a `disassembler` feature to the crate configuration that traces the operations executed and the state of the stack at runtime. This can be enabled by compiling with `--feature disassembler`. This will also gain a more sensible layout of code slices eventually.
