* Find variable values on parent scopesMiquel Sabaté Solà2024-12-201-12/+65
| | | | | | | If a given variable cannot be found on the current scope, attempt to go up the context hierarchy to find it. Signed-off-by: Miquel Sabaté Solà <mikisabate@gmail.com>
* assembler: Implement and add tests for operatorsMiquel Sabaté Solà2024-12-191-0/+35

* Add support for jumping into .proc'sMiquel Sabaté Solà2024-12-181-1/+1
| | | | | | | | Up until now defining a proc only involved pushing/popping the context. Here we also allow it to create a label so it can be referenced by instructions like jsr. Signed-off-by: Miquel Sabaté Solà <mikisabate@gmail.com>

* Prevent addresses which are out of boundsMiquel Sabaté Solà2024-12-181-7/+29
| | | | | | | | | | In some bad scenarios addresses might be pointing out of bounds (e.g. a reference further than 0xFFFF). This has to be avoided and through fuzzy testing we even got Rust panics for out of bounds u16 arithmetic. Hence, just go through usize for the actual computation and check with u16::MAX.

* Fix the mapping of addresses on labelsMiquel Sabaté Solà2024-12-161-0/+418
There was a big missunderstanding on how things were to be laid out in the end file, and so it was needed to create a proper understanding on what's a Mapping and what's a Segment. These turned out to be fundamental concepts that I failed to grok up until this commit. Hence, this commit re-arranges completely how variables and labels are stored in the Context, and how these objects can then be translated into bundles that can be spit out to the caller. This commit, besides introducing the new Mapping struct, also introduced a more general Object, which abstracts things from the Bundle struct, and allows us to pass certain metadata about the bundle at hand.
