This ensures inter-machine compatibility by not emitting any processor
specific instructions. This fixes the issue raised by the non AVX-512
supporting GitHub actions runners.
This allows a developer to easily dump a InlineLinkedList in the
debugger without having to manually running the list.
I needed this for a recent bug investigation in the Kernel.
This reverts commit e95eb7a51d.
This is causing some sort of list corruption, as evident by #7313
I haven't been able to figure it out yet, so lets revert this change
until I can figure out what's going on.
Problem:
- `typedef`s are read backwards making it confusing.
- `using` statements can be used in template aliases.
- `using` provides similarity to most other C++ syntax.
- C++ core guidelines say to prefer `using` over `typedef`:
https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#Rt-using
Solution:
- Switch these where appropriate.
Problem:
- `static` variables consume memory and sometimes are less
optimizable.
- `static const` variables can be `constexpr`, usually.
- `static` function-local variables require an initialization check
every time the function is run.
Solution:
- If a global `static` variable is only used in a single function then
move it into the function and make it non-`static` and `constexpr`.
- Make all global `static` variables `constexpr` instead of `const`.
- Change function-local `static const[expr]` variables to be just
`constexpr`.
-march=native specializes the binaries for the CPU features available on
the CPU the binary is being compiled on. This matches the needs of the
Toolchain, as it's always built and used on that machine only.
This should be safe for the github actions VMs as well, as they all run
on a standard VM SKU in "the cloud".
I saw small but notable improvements in end-2-end build times in my
local testing. Each compilation unit is on average around a second
faster on my Intel(R) Core(TM) i7-8705G CPU @ 3.10GHz.
Uncomment the tests that were disabled due to frequent freezes when
running without KVM. This also adds a new github actions group for
every single test, which makes it easier to browse test boundaries
during test runs.
Move catting the serial output log back to its own step, so that it
has higher visibility. The previous solution was also shown to not
actually cat the log in the case of a failed boot and timeout :^(.
skip() is supposed to end up keeping the previous iterator only one
index behind the current one, and restore_to() should actually do the
restore instead of just removing the now-useless source positions.
Fixes#7331.
When mmaping a Framebuffer from userspace, we need to check whether the
framebuffer device is actually enabled (e.g. graphical mode is being
used) or a textual VirtualConsole is active.
Considering the above state, we mmap the right VMObject to ensure we
don't have graphical artifacts if we change the resolution from
DisplaySettings, changed to textual mode and after the resolution change
was reverted, we will see the Desktop reappearing even though we are
still in textual mode.
If we tried to change the resolution before of this patch, we triggered
a kernel crash due to mmaping the framebuffer device again.
Therefore, on mmaping of the framebuffer device, we create an entire new
set of VMObjects and Regions for the new settings.
Then, when we change the resolution, the framebuffersconsole needs to be
updated with the new resolution and also to be refreshed with the new
settings. To ensure we handle both shrinking of the resolution and
growth of it, we only copy the right amount of available data from the
cells Region.
Instead of processing the input after receiving an IRQ, we shift the
responsibility to the io work queue to handle this for us, so if a page
fault occurs when trying to switch the VirtualConsole, the kernel can
handle that.
Previously, the ip would not be propagated correctly, and we would
produce invalid jumps when more than one level of nesting was involved.
This makes loops work :P
This will simply "link" any given module instances and produce a list of
external values that can be used to instantiate a module.
Note that this is extremely basic and cannot resolve circular
dependencies, and depends on the instance order.
Managing the instantiated modules becomes a pain if they're on the
stack, since an instantiated module will eventually reference itself.
To make using this simpler, just avoid copying the instance.
This fixes a FIXME and will allow linking only select modules together,
instead of linking every instantiated module into a big mess of exported
entities :P
This also optionally generates a test suite from the WebAssembly
testsuite, which can be enabled via passing `INCLUDE_WASM_SPEC_TESTS`
to cmake, which will generate test-wasm-compatible tests and the
required fixtures.
The generated directories are excluded from git since there's no point
in committing them.
This only tests "can it be parsed", but the goal of this commit is to
provide a test framework that can be built upon :)
The conformance tests are downloaded, compiled* and installed only if
the INCLUDE_WASM_SPEC_TESTS cmake option is enabled.
(*) Since we do not yet have a wast parser, the compilation is delegated
to an external tool from binaryen, `wasm-as`, which is required for the
test suite download/install to succeed.
This *does* run the tests in CI, but it currently does not include the
spec conformance tests.
We don't need it. A recent change to the ubuntu-20.04 image has made it
the default, causing builds to fail - we're installing and want to use
clang-12 anyway, so let's just get rid of the other installed versions.
If a line was larger than 1024 bytes or the file ended without a
newline character, can_read_line would return false.
IODevice::can_read_line() now reads until a newline is found or
EOF is reached.
fixes#5907
When reading from stdin, grep discards the last character,
even if that character is not \n.
This commit changes grep to no longer discard the last character from
a line.
This unifies how 3DFileViewer handles the initial file when starting
the application and when opening files later on via the menu.
Errors are shown both for the initial load as well as when loading
files later on. An error during file load no longer clears the
existing model.
It also adds support for specifying the filename as a command-line
argument.
The opened file's name is shown in the titlebar.
The HTML and Markdown preview modes both use an OutOfProcessWebView to
render the preview pane, and we were instantiating this view from GML.
This caused us to always spawn a WebContent process alongside every
TextEditor instance.
Fix this by deferring the OOPWV construction until we actually need it.
This makes launching TextEditor on a text file quite a bit faster. :^)
Instead of doing a full IPC round-trip for the client and server to
greet each other upon connecting, the server now automatically sends
a "fast_greet" message when a client connects.
The client simply waits for that message to arrive before proceeding.
(Waiting is necessary since LibGUI relies on the palette information
included in the greeting.)
This makes a few modifications to the statusbar text generation:
* Use the canonical U+XXXX representation of unicode characters.
* For control characters, display their alias instead of whitespace.
* Substitute RTL codepoints with U+FFFD so the text paints correctly.
* Only show the glyph's dimensions if it actually exists in the font.
This fixes#7286.
This introduces the UnicodeUtils file, which contains helper functions
related to Unicode. This is in contrast to StringUtils, whose functions
are not directly related to Unicode and are, in theory,
encoding-agnostic.
This hack allows for Boxes that have a background to be painted and a
border to accurately paint their border-radii if needed.
For that the box in with the background is drawn is extended to the
bordered_rect. The border is later drawn over this regardless.
Previously when drawing a Box that had all three, background, border
and a border-radius, there could be some white between the filling and
the border.
The struct BorderRadiusData contains the four radii of the box.
In case the specified borders are too large for the dimensions of the
box, they get scaled down.
