This gives the compiler enough information to optimize index validation
when using range-for to iterate over a Vector, drastically reducing the
cost of such loops.
These instructions now operate on the specified FPU stack entry instead
of always using ST(0) and ST(1).
FUCOMI and FUCOMIP also handle NaN values slightly better.
When we hit the last token, make the saved pointer point to the null
terminator instead of to the next token. This ensures that the next
call to strtok_r() returns null as expected.
Found by running GCC in UE. :^)
By using Gfx::Bitmap::is_path_a_supported_image_format() we can
automatically provide the image icon for all supported image formats,
without keeping a second list of image file extensions.
Bitmap::is_path_a_supported_image_format() and Bitmap::load_from_file()
now check the file extension with CaseSensitivity::CaseInsensitive.
This fixes a couple of inconsistencies, for example would
FileSystemModel::icon_for() recognize image files uppercase extensions
but couldn't create thumbnails for them (any attempt to create a bitmap
from such files would fail).
If we try to read a sentinel byte but the stream is fresh out of data,
we have to take care of the stream error and bail out right away, or
we'll hit an assertion when exiting the function soon after.
Fixes#3486.
Instead of always showing the preceding mallocation, prefer showing the
following one *if* it's closer to the audited address.
This makes it easier to find bugs where the access is just before an
allocation instead of just after it.
The pointers returned by malloc should always be 8-byte aligned on x86.
We were not consistent about this, as some ChunkedBlock size classes
were not divisible by 8.
This fixes some OOB reads found by running GCC in UE.
Start fleshing out basic support for floating-point instructions in the
UserspaceEmulator CPU.
This is all work done by @nico for #3576. I'm just merging it all in
this patch since it's a decent foundation to continue working on. :^)
As per this line in the specification:
Unless stated otherwise, a document’s encoding is the utf-8 encoding,
content type is "application/xml", URL is "about:blank", origin is an
opaque origin, type is "xml", and its mode is "no-quirks".

This patch makes Page weakable and allows page-less frames to exist.
Page is single-owner, and Frame is multiple-owner, so it's not sound
for Frame to assume its containing Page will stick around for its own
entire lifetime.
Fixes#3976.
This allows issuing asynchronous requests for devices and waiting
on the completion of the request. The requests can cascade into
multiple sub-requests.
Since IRQs may complete at any time, if the current process is no
longer the same that started the process, we need to swich the
paging context before accessing user buffers.
Change the PATA driver to use this model.
