2022-10-23	r/5186 feat(tvix/eval): initial attempt at setting lambda names	Vincent Ambo	1	-4/+14
	When compiling a lambda, take the name of the outer slot (if available) and store it as the name on the lambda. These names are then shown in the observer, and nowhere else (so far). It is of course common for these things to thread through many different context levels (e.g. `f = a: b: c: ...`), in this setup only the outermost closure or thunk gains the name, but it's better than nothing.

2022-10-05	r/5035 refactor(tvix/eval): introduce source::SourceCode type	Vincent Ambo	1	-5/+5
	This type hides away the lower-level handling of most codemap data structures, especially to library consumers (see corresponding changes in tvixbolt). This will help with implement `import` by giving us central control over how the codemap works.

2022-10-04	r/5033 refactor(tvix/eval): split observer traits in two	Vincent Ambo	1	-10/+14
	There are actually two different types of observers, the ones that observe the compiler (and emitted chunks from different kinds of expressions), and the ones that trace runtime execution. Use of the NoOpObserver is unchanged, it simply implements both traits.

2022-09-11	r/4799 fix(tvix/eval): use correct lambda address in observer	Vincent Ambo	1	-1/+1
	Instead of the reference to the Rc, print the address of the Rc itself. Change-Id: I4560598924db7d2864d5c4ae9af847aee2ea7eff Reviewed-on: https://cl.tvl.fyi/c/depot/+/6471 Tested-by: BuildkiteCI Reviewed-by: sterni <sternenseemann@systemli.org>
2022-09-10	r/4783 feat(tvix/eval): implement OpTailCall	Vincent Ambo	1	-0/+12
	If the last operation within a chunk is a function call, the call can be executed in the same call frame without increasing the depth of the call stack. To enable this, a new OpTailCall instruction (similar to OpCall) is introduced, but not yet emitted by the compiler.

2022-09-09	r/4775 feat(tvix/eval): implement DisassemblingObserver for compiler	Vincent Ambo	1	-2/+64
	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.
