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 4dd2ebf85a Rename ObjSections::count -> len 2024-06-09 16:10:34 -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

Luke Street 6b60c13834 Change REL "invalid relocation" to warning 
Also ensures that `block_relocations`
works to remove the warning

Luke Street 53c6d74a6b Fix addic/addic. handling in relocation tracker 
Resolves #57
 2024-06-03 18:01:55 -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 fdafe59e13 Adds `data:int` and `data:short` for asm output 
Fixes #41
 2024-04-30 18:03:45 -06:00
Luke Street e9a9ed0453 Fixes for switch analysis 
- When finalizing a block, restart analysis at
  the first block
- Check for default case in jump table entries
 2024-04-03 00:11:58 -06:00
Luke Street 96b13be11d Allow overriding jump table size analysis 
When the analyzer detects a jump table,
it will now check for an existing object
symbol at that address, using that size
if present.

Luke Street c44846d73f Allow absolute relocations to linker generated symbols 
Fixes #15
 2024-01-06 11:47:17 -07:00
Luke Street ebff47924f Add `links` field to config for overriding REL linkage 
By default, every REL is linked with every other REL. Some games, like Mario Party, link RELs individually, so the module IDs are not unique. To support this, the `links` field can be used to override which _other_ modules are included in a module's analysis.
 2023-11-18 23:37:50 -05:00
