2022-09-08	r/4744 refactor(tvix/eval): pass a VM reference to builtins	Vincent Ambo	1	-4/+14
	This makes it possible for builtins to force values on their own, without the VM having to apply a strictness mask to the arguments first.

2022-09-08	r/4741 feat(tvix/eval): ensure all errors always carry a span	Vincent Ambo	1	-3/+3
	Previously error spans were optional because the information about code spans was not available at runtime. Now that this information has been added, the error type will always carry a span. This change is very invasive all throughout the codebase. This is due to the fact that many functions that are called by the VM expected to return `EvalResult`, but this no longer works as the span information is not available to those functions - only to the VM itself. To work around this the majority of these functions have been changed to return `Result<T, ErrorKind>` instead and an accompanying macro in the VM constructs the "real" error. Note that this implementatino currently has a bug where errors occuring within thunks will yield the location at which the thunk was forced, not the location at which the error occured within the code. This will be fixed soon, but the commit is large enough as is.

2022-09-02	r/4588 feat(tvix/eval): introduce mechanism for defining builtins	Vincent Ambo	1	-0/+13
	Adds a new builtins module in which builtins can be constructed. The functions in this module should return a correctly structured value to be passed to the compiler's `globals`. This is wired up all the way to the compiler with an example `toString` builtin, available as a global. Note that this does not yet actually behave like the real toString, which has some differences from `Display`.

2022-09-02	r/4585 feat(tvix/eval): add initial representation of builtins	Vincent Ambo	1	-0/+66
	Builtins are represented as a Rust function pointer that accepts a vector of arguments, which represents variable arity builtins. Change-Id: Ibab7e662a646caf1172695d876d2f55e187c03dd Reviewed-on: https://cl.tvl.fyi/c/depot/+/6251 Tested-by: BuildkiteCI Reviewed-by: grfn <grfn@gws.fyi>
