This adds more recognition for inlined vector functions to the
decompiler, which can clean up a bunch of ugly looking code/`rlet`s.
Unfortunately, this changes the numbering of ops in the decomp, since
all the vector instructions get combined in a single "operation" by the
decompiler. I really tried to avoid having this ever happen in the
decompiler and this is one of the few cases where it has. So I had to
update a bunch of type casts.
For that reason I haven't turned this on in Jak 2 yet, although I am
planning to do that at some point. (probably at the same time as porting
back a bunch of jak 3 improvements to jak 2)

Add support for `as-type` macro, and detecting inline font methods. This
works in all three games but I've only updated jak 3's goal_src for now.
Eventually I will go back and work through the others, but I want to get
more decompiler features in first.

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:

This PR does a few cleanups:
- improve method names/comments/flags for `enemy.gc` and a few other
files
- fix `new-stack-matrix0` not working for jak 3
- add `matrix-copy!` detection for jak 3
- add `vector-copy!` detection

Two new flags were added to the Blender plugin to allow reusing the mod
and/or eye draws of the original model that is being replaced. Works
pretty well for eyes, but the blerc draws can cause some Z-fighting with
the non-moving parts of the model.
Also a small refactor to the merc replacement code to de-duplicate some
code by moving stuff to `gltf_util.cpp`.
This includes all the collision stuff needed to spawn `target`,
decompiles the sparticle code and adds some of the PC hacks needed for
merc to run (it doesn't work quite right and looks bad, likely due to a
combination of code copied from Jak 2 and the time of day hacks).
There are a bunch of temporary hacks (see commits) in place to prevent
the game from crashing quite as much, but it is still extremely prone to
doing so due to lots of missing functions/potentially bad decomp.

The `get-texture` macro replaces calls to `lookup-texture-by-id` and
`lookup-texture-by-id-fast`. The `defpart` macro detection was modified
to print a pair like `(texture-name tpage-name)` for the texture field
that gets turned into a `texture-id` constant. Only used in Jak 3 at the
moment, I'll probably go through the other games at a later point.

Additionally:

- Added a config file that allows overriding the process stack size set
by `stack-size-set!` calls
- Fix for integer multiplication with `r0`
- Fixed detection for the following macros:
- `static-attack-info`
- `defpart` and `defpartgroup` (probably still needs adjustments, uses
Jak 2 implementation at the moment)
- `sound-play` (Jak 3 seems to always call `sound-play-by-name` with a
`sound-group` of 0, so the macro has been temporarily defaulted to use
that)
One somewhat significant change made here that should be noted is that
the return type of `process::init-from-entity!` was changed to `object`.
I've been thinking about this for a while, since it looks a bit nicer
without the `(none)` at the end and I have recently encountered init
methods that early return `0`.
This sets out the bones of a Jak 3 build, many things are stubbed out,
guessed, or copied from Jak 2 but it should at least be good enough to:
run `task set-game-jak3`
launch the repl
run builds from the repl
build outputs themselves are untested but the build itself runs without
errors

Started at 349,880,038 allocations and 42s
- Switched to making `Symbol` in GOOS be a "fixed type", just a wrapper
around a `const char*` pointing to the string in the symbol table. This
is a step toward making a lot of things better, but by itself not a huge
improvement. Some things may be worse due to more temp `std::string`
allocations, but one day all these can be removed. On linux it saved
allocations (347,685,429), and saved a second or two (41 s).
- cache `#t` and `#f` in interpreter, better lookup for special
forms/builtins (hashtable of pointers instead of strings, vector for the
small special form list). Dropped time to 38s.
- special-case in quasiquote when splicing is the last thing in a list.
Allocation dropped to 340,603,082
- custom hash table for environment lookups (lexical vars). Dropped to
36s and 314,637,194
- less allocation in `read_list` 311,613,616. Time about the same.
- `let` and `let*` in Interpreter.cpp 191,988,083, time down to 28s.
This change adds a few new features:
- Decompiler automatically knows the type of `find-parent-method` use in
jak 1 and jak2 when used in a method or virtual state handler.
- Decompiler inserts a call to `call-parent-method` or
`find-parent-state`
- Removed most casts related to these functions
There are still a few minor issues around this:
- There are still some casts needed when using `post` methods, as `post`
is just a `function`, and needs a cast to `(function none)` or similar.
It didn't seem easy to change the type of `post`, so I'm not going to
worry about it for this PR. It only shows up in like 3 places in jak 2.
(and 0 in jak 1)
- If "call the handler if it's not #f" logic should probably be another
macro.
Fixes#805
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...
- state handlers that are not inlined lambdas have smarter type
checking, getting rid of 99.9% of the casts emitted (they were not
useful)
- art groups were not being properly linked to their "master" groups.
- `max` in `ja` in Jak 2 was not being detected.
Another huge PR...
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.

Normally, when they allocate a VagCmd, they do a bunch of stuff to clear
all the status bits and reset things
in particular the InitVAGCmd function does a lot
but for the stereo command, they do a lot less:
Which means that the new_stereo_command can just have random status bits
left over from whatever the last user had.
we seem to end up in a state where byte21 is set, and this causes
everything else to be wrong and off-by-one dma transfer. My guess is
that the original game avoided this bug due to lucky timing that I don't
understand.
I think the fix of just clearing byte21 is ok because there's no way
that the old value of the byte is useful after the command is
repurposed.
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.
- fix issue described in
https://github.com/open-goal/jak-project/issues/1939
- fix `text`, which was manually patched with the wrong offset (was
reading the symbol value off by one byte)
- clean up some random useless prints
- make the offline tests keep trying if there's a comparison error,
clean up the output a bit so the diffs are all at the end.
This PR does a few main things:
- finish decompiling the progress related code
- implemented changes necessary to load the text files end-to-end
- japanese/korean character encodings were not added
- finish more camera code, which is required to spawn the progress menu
/ init the default language settings needed for text
- initialized the camera as well
Still havn't opened the menu as there are a lot of checks around
`*target*` which I havn't yet gone through and attempted to comment out.
Favors the `lg` namespace over `fmt` directly, as this will output the
logs to a file / has log levels.
I also made assertion errors go to a file, this unfortunately means
importing `lg` and hence `fmt` which was attempted to be avoided before.
But I'm not sure how else to do this aspect without re-inventing the
file logging.
We have a lot of commented out prints as well that we should probably
cleanup at some point / switch them to trace level and default to `info`
level.
I noticed the pattern of disabling debug logs behind some boolean,
something to consider cleaning up in the future -- if our logs were more
structured (knowing where they are coming from) then a lot this
boilerplate could be eliminated.
Closes#1358
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
