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.

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...
This PR adds detection of the `launch-particles` and `seconds-per-frame`
macros to the decompiler, removing a lot of bloat and hiding many
process register uses.
I also added `og:preserve-this` comments to as many manual patches and
comments as I could, which will soon be used in conjunction with CI to
hopefully catch any regressions in future big decomp update PRs.
I have some concerns about the `launch-particles` macro (more details in
`sparticle-launcher.gc`) , but thus far, I have not seen anything break
yet.

Adds sprite distort, fixes buggy sprite rendering in progress, adds
scissoring support (used in various scrolling menus) and a very basic
implementation of `blit-displays`. This is enough to make the fade
effect in the progress menu work, along with all the menus working
properly without needing to use the REPL. This does not make screen
flipping and the filter when failing a mission work.
Added support in the decompiler for detecting `dma-buffer-add-gs-set`
and `dma-buffer-add-gs-set-flusha` and updated all of the Jak 2 code to
use it. Readability improved!
Fixes decompiler issue with `with-dma-buffer-add-bucket` not inlining
forms which broke syntax. Fixes store error warnings showing up for
non-existent stores, there is now a dedicated pass for this at the end.
I started work on making `BITBLTBUF` stuff work in the DirectRenderer,
but stopped for now because it wasn't strictly necessary. It will still
assert like before.
Updates the decompiler for the new format and there's new macros. This
new format should be easier to read/parse.
Also rewrote `sp-init-fields!` (both jak 1 and 2) from assembly to GOAL.
Hopefully I did not miss any regressions in Jak 1/2 while updating the
files, it's a lot.
There are *a lot* of file changes and while I have carefully gone
through every gsrc change to fix up manual patches, there might still be
spots that I missed.
Manual patches in:
- `tomb-boulder`: a few `ppointer->handle`s (I think) were not being
decompiled properly (all used in combination with `clone-anim-once`)
- `ruins-obs`, `pillar-collapse`: `art-joint-anim` casts
- `tomb-beetle`: commented out a call to `shadow-control-method-14` that
was crashing the game when spawning the beetles
- `grunt-mech`: commented out `(.mula.s)` instruction
Notes:
- `enemy-info`'s `idle-anim-script` is most likely a `(pointer
idle-control-frame)`, however, some `nav-enemy-info` labels set it to
`#f` (first encountered in `tomb-beetle`, but also present in `hal`,
`roboguard` and `metalkor-setup`), which crashes the decompiler. This
may become a problem in the future when we eventually get to these
files. For this PR, I made `tomb-beetle` decompile with
`idle-anim-script` set to `#f` and have not noticed any issues/crashes
with that.
- `tomb-boulder` compiles and doesn't crash, but when trying to play the
Daxter chase sequence, the boulder sometimes either spawns at the origin
or spawns in the correct place, but doesn't move.

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?
The VU programs for the ocean renderer have changed a bit and
`ocean-texture` has a bunch of new stuff, otherwise things are
relatively similar to Jak 1.
This is the first time I used mips2c and I'm not sure I did it 100%
right, so that should be double-checked.
And everything else needed for them!
A couple functions are bad currently.
- fixes#1929 - untested on linux
- fixes#1924 - now you need to type `,` before a lambda you want to put
in a pair.
- fix debugger symbol table in jak 2
- made the decompiler output `(meters 2)` instead of `(meters 2.0)`
- fixed a bug with the bitfield enum special -1 case
- made bad game text decomp not exit the decompiler
- added `editable-player` and `script`
Fixes https://github.com/open-goal/jak-project/issues/1821 by adding a
special case for `new` method calls where the argument with type
`symbol` is actually an address to uninitialized structure on the stack.
Fixes https://github.com/open-goal/jak-project/issues/1849 (or at least
the cause of the issue Vaser gave in chat, and one random one I found in
`debug-sphere`)
Fixes https://github.com/open-goal/jak-project/issues/1853
Fixes https://github.com/open-goal/jak-project/issues/1857 by moving the
cast into the cond if the body is a single form and the destination type
is a bitfield/enum which is likely to work well. Seems to work on the
examples we could find in jak 1 and jak 2.
Also fixes an issue with casts on the result of `handle->process` (a
common place to use casts)
the output of process->handle is a plain process. Most of the time, you
end up casting this to a more specific. If you add a cast on every use
of the variable, the decompiler will decide to change the type of that
variable to the more specific type, and this breaks the handle cast.
so previously it was impossible to get code like
```
(let* ((s2-0 (the-as swingpole (handle->process (-> self control hack))))
(gp-0 (-> s2-0 dir))
)
```
But now it will work
Rewrites specific kinds of lets where the return value of the `set!`
itself is meant to be used to just be `set!`s. Implemented at the let
rewrite level. Seems to work for Jak 2 so far.
Fixes#1854 .
I wasn't able to 100% complete `debug` due to a bunch of level boundary
debug stuff I couldn't figure out. But, I added a ref test and
documented/copied over everything else into goal_src.
Most of the functions that existed in Jak 1 are identical, others got an
extra param or 2 and some now make copies of arguments instead of
modifying them. There's a bunch of new functions, including all of the
debug functions that used to be in `level-boundary` are now in `debug`.
At the very end of `debug` there's also some weird asm functions
checking for some EE memory controller bug (not sure what's up with
that)?
