There's now only 3 addressing modes: stack, constant, and member.
Self, class, and nil are now present respectively in the first 3 stack
slots. Global and class constants are moved to local constants when
compiling. Named globals is only present on editor to use on tool
singletons, so its use now emits a new instruction to copy the global to
the stack.
This allow us to further optimize the VM later by embedding the
addressing modes in the instructions themselves, which is better done
with less permutations.
This is meant for testing the GDScript implementation, not for testing
user scripts nor testing the engine using scripts.
Tests consists in a GDScript file and a .out file with the expected
output. The .out file format is: expected status (based on the enum
GDScriptTest::TestStatus) on the first line, followed by either an error
message or the resulting output. Warnings are added after the first
line, before the output (or compiler errors) if the parser pass without
any error.
The test script must have a function called `test()` which takes no
argument. Such function will be called by the test runner. The test
should not have any dependency unless it's part of the test too. Global
classes (using `class_name`) are registered before the runner starts, so
those should work if needed.
Use the command `godot --gdscript-generate-tests
godot-source/modules/gdscript/tests/scripts` to update the .out files
with the current output (make sure the output are the expected values
before committing).
The tests themselves are part of the doctest suite so those can be
executed with `godot --test`.

When the type cannot be validated at compile time, the runtime must do a
check to ensure type safety is kept, as the code might be assuming the
return type is correct in another place, leading to crashes if the
contract is broken.
This ensures that annotations that rely on the datatype (such as
@export) can validated it timely, allowing compound expressions instead
of only literal values.
- Use `Array[type]` for type-hints. e.g.:
`var array: Array[int] = [1, 2, 3]`
- Array literals are typed if their storage is typed (variable
asssignment of as argument in function all). Otherwise they are
untyped.
When this code was changed for 4.0, a "break" statement inside a for loop in 3.x was changed to "return".
This means that the two special cases (autoloads and input actions) are never checked.
Removing the return lets these work properly in the editor.
(Also reorder conditionals to short-circuit and avoid expensive methods.)
-Added a new method in Resource: reset_state , used for reloading the same resource from disk
-Added a new cache mode "replace" in ResourceLoader, which reuses existing loaded sub-resources but resets their data from disk (or replaces them if they chaged type)
-Because the correct sub-resource paths are always loaded now, this fixes bugs with subresource folding or subresource ordering when saving.
- Based on C++11's `thread` and `thread_local`
- No more need to allocate-deallocate or check for null
- No pointer anymore, just a member variable
- Platform-specific implementations no longer needed (except for the few cases of non-portable functions)
- Simpler for `NO_THREADS`
- Thread ids are now the same across platforms (main is 1; others follow)
