Luke Street c484952912 Support generating RELs with non-sequential module IDs 
Uses the module ID from the configuration, if present,
falling back to the standard behavior of sequential
module IDs.

Luke Street 9c12efa64e Update orthrus-ncompress 2024-06-10 17:40:46 -06:00
Luke Street af3bcf5f9e Create gap symbols at the end of sections 
Before, the end of the section
was not considered, so missing
symbols at the end of a section
would omit that data entirely.

Luke Street 761a940f9e Match original "exec" for REL sections 
mwld writes empty code sections as
NULL type in the PLF, but sometimes
the original REL has the exec flag
set for these sections. Match the
original value.

Luke Street eb7c3e9d9f Detect _savevr/_restvr + check in RELs 
Some games include a copy of MW
runtime.c in RELs. Easy to check.

Some games also include _savevr/
_restvr for AltiVec. This is weird
but we can handle it as well.

Luke Street 3289b2a3aa Ignore invalid instructions 
This could be a bad idea, but
it's unclear how to properly
handle these cases.

Resolves #55

Luke Street b44aa78c49 Fix REL alignment after section data 2024-06-10 00:38:06 -06:00
Luke Street 4ea4ec86d0 Partially revert "Rework section alignment handling" 
It turns out we can't actually
trust mwld to put our alignment
values in the PLF. Sad.

Luke Street 4dd2ebf85a Rename ObjSections::count -> len 2024-06-09 16:10:34 -06:00
Luke Street 46cf0be183 Add U8 (newer .arc) support 
Supports the U8 .arc format, just
like the older RARC format.

`u8 list`, `u8 extract` and support
for U8 archive paths in config.yml

Luke Street 255123796e Instruction disassembly in `dol diff` 
When a function diff is detected in
`dol diff`, objdiff-core is used to
print a detailed view highlighting
any differences.

Luke Street d63111466b SN GCC DWARF improvements 
Now emits all DWARF tags for
Spongebob Squarepants: Creature
from the Krusty Krab properly.

Resolves #46
 2024-06-03 18:48:28 -06:00
Luke Street 61cd72cd11 Support address in config symbol references 
Example: `symbol_name!.data:0x1234`
Allows disambiguating local symbols
with the same name.

Supported in `extract` and
`add_relocations` in config.yml

Resolves #58
 2024-06-03 18:08:06 -06:00
Luke Street 4701de32f6 Check for existing function with `bl` 
Ensures that the analyzer won't
create a function when the target
is already contained within a
function. Useful with manual asm
that would otherwise trip up the
analyzer.

Partial work for #56
 2024-06-03 18:06:10 -06:00
Luke Street 6b60c13834 Change REL "invalid relocation" to warning

Luke Street d9770c48b2 Version 0.8.3 2024-05-19 23:09:16 -06:00
Luke Street c3f3ea58e8 Support `block_relocations` and `add_relocations` in `config.yml` 
This allows more granular control over generated relocations.

Also optimizes relocation address validity checks,
leading to ~20% faster relocation analysis.

Config example:
```
block_relocations:
# Block any relocation pointing to this address.
- target: .data:0x80130140
# Block any relocation originating from this address.
- source: .text:0x80047160
  # (optional) End address to make it a range.
  end: .text:0x800471A8

add_relocations:
# Inserts or overwrites a relocation.
# From: `subi r3, r3, 0x7657`
# To: `li r3, mesWInsert-0x1@sda21`
- source: .text:0x800473F4
  type: sda21
  target: mesWInsert
  addend: -1
```

Luke Street c1c4373e53 Prefer references to `_savegpr_14` over `__savegpr` 
Same for `__restore_gpr`, `__save_fpr` and `__restore_fpr`.
A common issue that can be solved with a little bit
of special-casing.
