* Implement the .include statementMiquel Sabaté Solà2025-01-091-40/+17
| | | | | | | | | | | | | | This needed some heavy lifting when it comes to how files were located. This means that statements like .include/.incbin now take into consideration a new list made out of SourceInfo, which holds enough information to translate from which file a node comes from. This has also been added into errors, so they are more informative on what went wrong. In order to tests this, besides all the regular unit tests, a new e2e test has been added.

* nasm: Allow file paths for the configurationMiquel Sabaté Solà2024-12-221-9/+17
| | | | | | | This opens up the door for developers to pass their own configuration files. Signed-off-by: Miquel Sabaté Solà <mikisabate@gmail.com>
* Transform mapping configurations into toml filesMiquel Sabaté Solà2024-12-221-347/+183
| | | | | | | | This will allow the creation of configuration files that can live outside of this tree, so developers can fine tune configuration files of their own without having to pick up whatever is currently available. Signed-off-by: Miquel Sabaté Solà <mikisabate@gmail.com>
* Add support for UxROM chipsMiquel Sabaté Solà2024-12-201-2/+161
| | | | | | I have also added an end-to-end test for it. Signed-off-by: Miquel Sabaté Solà <mikisabate@gmail.com>
* Remove unneeded public referencesMiquel Sabaté Solà2024-12-181-1/+1
| | | | | | | | Some of the functions are actually private, so don't export them. Moreover, there was an import cycle which was not needed and was forcing a public import. Remove that as well. Signed-off-by: Miquel Sabaté Solà <mikisabate@gmail.com>
* Fix the mapping of addresses on labelsMiquel Sabaté Solà2024-12-161-99/+318
| | | | | | | | | | | | | | | | | 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.

* Re-work the handling of segments in the assemblerMiquel Sabaté Solà2024-12-121-1/+1
| | | | | | | | There were a lot of assumptions on the assembler that stemmed from a fundamental missunderstanding from my side on how segments are laid out on the final file. This commit is the first step to address this. Signed-off-by: Miquel Sabaté Solà <mikisabate@gmail.com>
* Re-work the support on labels, variables and jumpsMiquel Sabaté Solà2024-12-121-0/+14
| | | | | | | | | | | As a way to firstly adapt on the latest changes from the parser since 184c39579227 ("Re-work the parser from scratch"), the assembler had to leave out some features on 16114b2ca358 ("Adapt the assembler to the changes on the parser"). This commit reintroduces support for settings labels, variables and referencing them, while also providing a more robust implementation at that.

* Adapt the assembler to the changes on the parserMiquel Sabaté Solà2024-12-121-14/+11
| | | | | | | | | | | As of 184c39579227 ("Re-work the parser from scratch") the parser has a proper AST, and the assembler has to traverse it accordingly. Moreover, the assembler has been stripped from a lot of unneeded memory allocations and it's overall more keen on using mere references when possible.

* Add basic support for macrosMiquel Sabaté Solà2024-12-121-2/+23
| | | | | | | Macros can now be described with the '.macro' control statement, but no parameters can be given and it's overall pretty brittle. Signed-off-by: Miquel Sabaté Solà <mikisabate@gmail.com>
* Add support for proceduresMiquel Sabaté Solà2024-12-121-2/+31
| | | | | | | Procedures are marked with the '.proc' control statement and work both as a scoping mechanism and as a label that can be referenced. Signed-off-by: Miquel Sabaté Solà <mikisabate@gmail.com>
* Add support for branchingMiquel Sabaté Solà2024-12-121-1/+1
| | | | | | | | This is a bare bones implementation of it, and there's a lot of nuance that it's being missed, but at least the fundamentals have been implemented already. Signed-off-by: Miquel Sabaté Solà <mikisabate@gmail.com>
* Add the notion of mappingMiquel Sabaté Solà2024-12-121-0/+66
Mappings and segments are fundamental blocks on how code is distributed both on the actual ROM File and in the memory layout. Signed-off-by: Miquel Sabaté Solà <mikisabate@gmail.com>
