This is a set of functions that allow you to convert between arbitrary
IEEE 754 floating point types, as long as they can be represented
within 64 bits. Conversion methods between floats and doubles are
provided, as well as a generic `float_to_float()`.
Example usage:
#include <AK/FloatingPoint.h>
double val = 1.234;
auto weird_f16 =
convert_from_native_double<FloatingPointBits<0, 6, 10>>(val);
Signed and unsigned floats are supported, and both NaN and +/-Inf are
handled correctly. Values that do not fit in the target floating point
type are clamped.
Instead we just use a specific constructor. With this set of
constructors using curly braces for constructing is highly recommended.
As then it will not do too many implicit conversions which could lead to
unexpected loss of data or calling the much slower double constructor.
Also to ensure we don't feed (Un)SignedBigInteger infinities we throw
RangeError earlier for Durations.
This means it can take any (un)signed word of size at most Word.
This means the constructor can be disambiguated if we were to add a
double constructor :^).
This requires a change in just one test.
This allows using different options for rounding, like IEEE
roundTiesToEven, which is the mode that JS requires.
Also fix that the last word read from the bigint for the mantissa could
be shifted incorrectly leading to incorrect results.
Now that the Spinlock code is not dependent on architectural specific
code anymore, we can move it back to the Locking folder. This also means
that the Spinlock implemenation is now used for the aarch64 kernel.
This commit updates the lock function from Spinlock and
RecursiveSpinlock to return the InterruptsState of the processor,
instead of the processor flags. The unlock functions would only look at
the interrupt flag of the processor flags, so we now use the
InterruptsState enum to clarify the intent, and such that we can use the
same Spinlock code for the aarch64 build.
To not break the build, all the call sites are updated aswell.
This commit adds the concept of an InterruptsState to the kernel. This
will be used to make the Spinlock code architecture independent. A new
Processor.cpp file is added such that we don't have to duplicate the
code.
Applications using the Vim emulation engine now support line-wise text
selection.
We already have support for character-wise text selection, by pressing
`v` from normal mode.
However now can also trigger line-wise text selection by pressing
`shift+v` from normal mode, and then using vertical motion commands
(e.g. `j` or `k`) to expand the selection. This is a standard vim
feature.
In visual line mode the following operations are supported:
* `escape`: back to normal mode
* `u`: convert to lowercase
* `U`: convert to uppercase
* `~`: toggle case
* `ctrl+d`: move down by 50% of page height
* `ctrl+u`: move up by 50% of page height
* `d` or `x`: delete selection
* `c`: change selection
* `y`: copy selection
* `page up`: move up by 100% of page height
* `page down`: move down by 100% of page height
Notably I didn't implement pressing `v` to go to regular
(character-wise) visual mode straight from visual line mode. This is
tricky to implement in the current code base, and there's an
alternative, which is to take a detour via normal mode.
This commit fixes a bug found when passing exotic values in the
grid-template-columns (or grid-template-rows) which are not yet
supported.
The bug seems to have been something like:
grid-template-columns: 0 minmax(0, calc(10px - var(--some-color)));
so Dialogs can join the modal chain of the window parenting them.
Fixes apps that use FileSystemAccess to sandbox FilePicker not
respecting its blocking effect.
Refactors restore helper into move_to_front_and_make_active().
Fixes not bringing all modal children to the front when any modal
child or its modeless parent is clicked.
This was intentionally enabled with WindowModes as a new Taskbar
convenience, but on second thought, it doesn't add up visually.
Taskbar buttons show blockers' context menus when available,
which is a bit confusing when the window isn't visible. The
modeless window's disabled context menu options and inactive title
bar also contradict the button. So, this patch reenables the
restriction for now. Blocking modals you don't want to answer to
immediately can still be tucked away on another workspace.
This exception is necessary for ComboBoxes used in some blocking
Dialogs. CaptureInput is now the only mode which can spawn from
a blocking modal and it won't accept any children of its own.
Globally shared MemoryManager state is now kept in a GlobalData struct
and wrapped in SpinlockProtected.
A small set of members are left outside the GlobalData struct as they
are only set during boot initialization, and then remain constant.
This allows us to access those members without taking any locks.
This is an editorial change in the Temporal spec.
Now that this is spec'd as either an Object or undefined, we can change
the parameter type from arbitrary JS::Value to JS::Object*.

The protocol of the origin is used for checking if the a file://
iframe is allowed to be loaded (a document with a file:// origin
can load other files in iframes).
This used to be the case, but was changed in
6e71e400e6, which broke file:// iframes.
