This facility was added in 15a1d9a, but isn't being used for anything.
It wasn't even hooked up to LibGUI for applications to use.
Relevant use-cases, such as the most prominent one in `AnalogClock`, use
`GUI::Window::set_frameless()` instead.
From what I can tell, this facility was added to WSWindow/GWindow in
2019 in 9b71307. I only found a single place in the codebase still using
this facility: `WindowServer::Menu::start_activation_animation()`. A
subtle fade-out animation that happens when a menu item is selected, and
the menu disappears.
I think our compositing facilities have improved enough to make this
facility redundant. The remaining use mentioned above was ported to just
directly blit the fade-out animation instead of requesting it from
WindowServer.
While this is a useful piece of information it means that diff is
producing hunks that are not of a valid normal diff format. This breaks
the ability to redirect the output of diff to a file to generate a
patch.
Apple Clang 14.0.3 (Xcode 14.3) miscompiles this builtin on AArch64,
causing the borrow flag to be set incorrectly. I have added a detailed
writeup on Qemu's issue tracker, where the same issue led to a hang when
emulating x86:
https://gitlab.com/qemu-project/qemu/-/issues/1659#note_1408275831
I don't know of any specific issue caused by this on Lagom, but better
safe than sorry.
GCC 14 (https://gcc.gnu.org/g:2b4e0415ad664cdb3ce87d1f7eee5ca26911a05b)
has added support for the previously Clang-specific add/subtract with
borrow builtins. Let's use `__has_builtin` to detect them instead of
assuming that only Clang has them. We should prefer these to the
x86-specific ones as architecture-independent middle-end optimizations
might deal with them better.
As an added bonus, this significantly improves codegen on AArch64
compared to the fallback implementation that uses
`__builtin_{add,sub}_overflow`.
For now, the code path with the x86-specific intrinsics stays so as to
avoid regressing the performance of builds with GCC 12 and 13.
Previously, an audio loader could succeed for an HTMLVideoElement that
contains a video file, which caused the duration to be set to the bogus
duration of the audio loader instead of the correct duration from the
video container. Instead of setting the duration based on audio always,
set it to the video duration if we are creating a video element.
There are hundreds of test262 tests with the following metadata line:
flags: []
Other engine runners are apparently able to ignore those lines, so we
should as well.
On style update, we have to preserve the invariant established when we
built the layout tree - some properties are applied to the table wrapper
and the table box values are reset to their initial values.
This also ensures that the containing block of a table box is always a
table wrapper, which isn't the case if we set absolute position on the
box instead of the wrapper.
Fixes#19452.
This is only needed because currently spec doesn't explicitly define
that navigable should have a pointer to associated container and when
this pointer should be set.
If more than one file is specified on the command line and the `-L`
option is used, the totals field will show the longest line
encountered; it is not a sum like the other values.
The previous version had a sequence of calls that are likely not
optimized out, while this version is strictly a sequence of static type
conversion which are always fully optimized out.
