2024-01-01linker: fix some allocator referencesAndrew Kelley
2024-01-01compiler: miscellaneous branch progressAndrew Kelley
implement builtin.zig file population for all modules rather than assuming there is only one global builtin.zig module. move some fields from link.File to Compilation move some fields from Module to Compilation compute debug_format in global Compilation config resolution wire up C compilation to the concept of owner modules make whole cache mode call link.File.createEmpty() instead of link.File.open()

2023-11-04elf: redo strings management in the linkerJakub Konka
* atom names - are stored locally and pulled from defining object's strtab * local symbols - same * global symbols - in principle, we could store them locally, but for better debugging experience - when things go wrong - we store the offsets in a global strtab used by the symbol resolver

2023-09-21compiler: move struct types into InternPool properAndrew Kelley
Structs were previously using `SegmentedList` to be given indexes, but were not actually backed by the InternPool arrays. After this, the only remaining uses of `SegmentedList` in the compiler are `Module.Decl` and `Module.Namespace`. Once those last two are migrated to become backed by InternPool arrays as well, we can introduce state serialization via writing these arrays to disk all at once. Unfortunately there are a lot of source code locations that touch the struct type API, so this commit is still work-in-progress. Once I get it compiling and passing the test suite, I can provide some interesting data points such as how it affected the InternPool memory size and performance comparison against master branch. I also couldn't resist migrating over a bunch of alignment API over to use the log2 Alignment type rather than a mismash of u32 and u64 byte units with 0 meaning something implicitly different and special at every location. Turns out you can do all the math you need directly on the log2 representation of alignments.

2023-09-13elf: add u64 to usize casts where requiredJakub Konka
2023-09-12elf: clean up and unify symbol ref handling in relocsJakub Konka
Also, this lets us re-enable proper undefined symbols tracking.
