water111 7348e6a4ff [decompiler] Update vector ops, reduce casts (#3849)
Update the decompiler to use the new vf macros.

Also, fix a bunch of silly casting issues where accessing inline fields
with an offset of 0 would be better than a cast:

Tyler Wilding 258fd75cd6 decomp: update naming across jak2/3 (#3395) 2024-03-03 20:49:40 -05:00
Hat Kid ea93d32acc decomp3: more misc files (#3349)
- `pat-h`
- `engines`
- `res-h`
- `res`
- `fact-h`
- `game-info-h`
- `wind-h`
- `merc-h`
- `shadow-vu1-h`
- `shadow-cpu-h`
- `dynamics-h`
- `memcard-h`
- `surface-h`
- part of `gui-h`
- `ambient-h`
- `speech-h`
- `prototype-h`
- `smush-control-h`
- `generic-merc-h`
- `generic-work-h`
- `collide-func-h`
- `collide-mesh-h`
- `collide-shape-h` (only missing the `new` method for `collide-shape`
because we don't have `process-drawable` yet and that also needs joint
stuff etc.)
- `collide-touch-h`
- `collide-edge-grab-h`
- `lightning-h`

This also adds argument name remaps for the `relocate` and `mem-usage`
methods (Jak 1 and 2 ref tests were updated, but not the gsrc).

ManDude cd68cb671e deftype and defmethod syntax major changes (#3094)
Major change to how `deftype` shows up in our code:
- the decompiler will no longer emit the `offset-assert`,
`method-count-assert`, `size-assert` and `flag-assert` parameters. There
are extremely few cases where having this in the decompiled code is
helpful, as the types there come from `all-types` which already has
those parameters. This also doesn't break type consistency because:
  - the asserts aren't compared.
- the first step of the test uses `all-types`, which has the asserts,
which will throw an error if they're bad.
- the decompiler won't emit the `heap-base` parameter unless necessary
now.
- the decompiler will try its hardest to turn a fixed-offset field into
an `overlay-at` field. It falls back to the old offset if all else
fails.
- `overlay-at` now supports field "dereferencing" to specify the offset
that's within a field that's a structure, e.g.:
```lisp
(deftype foobar (structure)
  ((vec    vector  :inline)
   (flags  int32   :overlay-at (-> vec w))
   )
  )
```
in this structure, the offset of `flags` will be 12 because that is the
final offset of `vec`'s `w` field within this structure.
- **removed ID from all method declarations.** IDs are only ever
automatically assigned now. Fixes #3068.
- added an `:overlay` parameter to method declarations, in order to
declare a new method that goes on top of a previously-defined method.
Syntax is `:overlay <method-name>`. Please do not ever use this.
- added `state-methods` list parameter. This lets you quickly specify a
list of states to be put in the method table. Same syntax as the
`states` list parameter. The decompiler will try to put as many states
in this as it can without messing with the method ID order.

Also changes `defmethod` to make the first type definition (before the
arguments) optional. The type can now be inferred from the first
argument. Fixes #3093.

Hat Kid fc43870d85 decompiler: obj -> this, set-time! and time-elapsed? macros (#3026)
This renames the method object in `defmethod`s to `this` and adds
detection for the `set-time!` and `time-elapsed?` macros.

Definitely my biggest PR yet...

ManDude fe491c2b5e [opengoal] make none a child of object (#3001)
Previously, `object` and `none` were both top-level types. This made
decompilation rather messy as they have no LCA and resulted in a lot of
variables coming out as type `none` which is very very wrong and
additionally there were plenty of casts to `object`. This changes it so
`none` becomes a child of `object` (it is still represented by
`NullType` which remains unusable in compilation).

This change makes `object` the sole top-level type, and the type that
can represent *any* GOAL object. I believe this matches the original
GOAL built-in type structure. A function that has a return type of
`object` can now return an integer or a `none` at the same time.
However, keep in mind that the return value of `(none)` is still
undefined, just as before. This also makes a cast to `object`
meaningless in 90% of the situations it showed up in (as every single
thing is already an `object`) and the decompiler will no longer emit
them. Casts to `none` are also reduced. Yay!

Additionally, state handlers also don't get the final `(none)` printed
out anymore. The return type of a state handler is completely
meaningless outside the event handler (which is return type `object`
anyway) so there are no limitations on what the last form needs to be. I
did this instead of making them return `object` to trick the decompiler
into not trying to output a variable to be used as a return value
(internally, in the decompiler they still have return type `none`, but
they have `object` elsewhere).

Fixes #1703 
Fixes #830 
Fixes #928

Tyler Wilding 8b12553d15 d/jak2: first pass at decompiling the core vehicle/traffic code (#2058)
Effects the following files:
- [x] vehicle-rider
- [x] vehicle-control
- [x] vehicle-effects
- [x] vehicle
~~- [ ] vehicle-util~~
- [x] vehicle-physics
- [x] vehicle-states
~~- [ ] vehicle-guard~~
~~- [ ] traffic-engine~~
~~- [ ] traffic-manager~~

With the exception of traffic-engine, most of these files are either
done or have 1-3 stubborn functions remaining. Draft while I try to
resolve as many as possible / cleanup names and such.

Tyler Wilding 6181c6c997 decomp: output mips2c method/function declarations to the _disasm.gc file (#2054)
When working with mips2c recently, I noticed adding the
`defmethod-mips2c` or `def-mips2c` code was a manual step. This is a bit
tedious to have to go and do yourself, but more importantly you have to
manually go and find the right spot in the source file else you might be
declaring it too early or too late.

This will automatically output the declaration for methods, and a
half-finished comment for the functions. I wasn't able to fully output
the function one because it seems the signature info from `all-types`
doesn't make it all the way through -- but maybe I'm wrong or this is an
easy fix?

water111 029983270e [decomp] target cleanup (#2021)
everything up to collide-reaction-target (which is mostly done, but
could use a few more names)

Tyler Wilding 84ef64398e d/jak2: finish process-drawable, collide-reaction-target, target-anim, almost target-part and gun-part (#2012)
- target-part
- ;; ERROR: Failed to convert to atomic ops: Variable could not be
constructed from register r0 in `process-drawable-shock-wall-effect`
- gun-part
  - missing sparticle decompiling case it seems related to `L155`

This is pretty rough but...im excited to see it working :)

Hat Kid da5aef8d60 decomp: finish target-[util|darkjak|swim|gun] | water | water-anim | crates | dark-eco-pool, fix skelgroup detection, add failed store/load warnings and clean up jak 3 config (#1958)
Almost done:
- `target-handler` (`(none)` event handler casts and CFG error)
- `target2` (`(none)` event handler casts)
- `powerups` (`cloud-track` does some weird stuff with `handle`s)
- `gun-states` (CFG error)

Some progress in:
- `water-flow`

Additionally:

- Clean up the two year old Jak 3 config file and add a config skeleton
(disassembling seems to not have worked, but I was able to dump obj
files and the `all_scripts` file)
- Fix automatic skelgroup detection and `defskelgroup` macro for Jak 2
(closes #1950)
- When a function decompiles without any major errors, a warning is
generated with the op id for each unresolved load and store that will
likely fail to compile (closes #1933)

water111 d52739226c [decomp] decompile decomp.gc (#1936)
A few issues:
- lwidea's fr3 is getting loaded and unloaded all the time
- the debug line drawing clipping is wrong (doesn't seem wrong in pcsx2,
so I think this is on us)
- nothing actually using vis data yet
- at a large distance, our view frustum culling seems slightly too
aggressive (might be that viewport scissoring is wrong)
- in the city, things seem darker as you move away. unclear how this is
happening (fog?)
