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:

Hat Kid 51d008f9ab decompiler: detect and turn inverse mult to div (#3795)

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 da3caf7b28 [decompiler] fix in-place ops not getting detected sometimes (#2810) 2023-07-08 07:34:38 +01:00
ManDude 6884b0f73e start blit-displays decomp & renderer + improve decompilation of some DMA macros (#2616)
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.

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 3d4dfb2077 [decomp] Decompile some time-of-day stuff, support new style Jak 2 time of day (#1943)
- Add "tfrag-water" tfrag tree support (may just be the same as Jak 1's
'dirt' for the settings)
- Add "tfrag-trans" tfrag tree support, reusing "trans-tfrag" from jak
1.
- Add a hack to `LinkedObjectFileCreation` to handle `oracle`, which is
accidentally multiply defined as a type leftover from jak 1 (an entity
in village1), and level info for jak 2.
- Add `VI1.DGO`
- add `time-of-day.gc`, and a few other stub functions so it works
- Set up some time of day stuff in GOAL for jak 2/PC renderers
- Clean up time of day in c++ renderers, support the more complicated
weight system used by jak 2 (backward compatible with jak 1, thankfully)

The mood functions now run, so this could cause problems if they rely on
stuff we don't have yet. But it seems fine for ctysluma and prison for
now.
