GCC 13 was released on 2023-04-26. This commit fixes Lagom build errors
when using an updated host toolchain:
- Adds a workaround for a bug in constraint handling, which made LibJS
fail to compile: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=109683
- Silences the new `-Wdangling-reference` diagnostic globally. It
produces multiple false positives with no clear way to silence them
without `#pragmas`.
- Silences `-Wself-move` in `RefPtr` tests as GCC 13 adds this
previously Clang-exclusive warning.

This ensures that all visit_edges implementations include a call to
Base::visit_edges. In particular, this gives three nice benefits:
- The call can't be forgotten (the main benefit, of course).
- All of the calls look the same. In other words, always use "Base"
instead of the actual concrete class.
- Ensure the object has a call to JS_CELL or JS_OBJECT in the
definition. Otherwise, Base will not be defined and the call will
not compile.

Some hardware/software configurations crash KVM as soon as we try to
start Serenity. The exact cause is currently unknown, so just fully
revert it for now.
This reverts commit 897c4e5145474d55b247a4a3b5e6bf5420279e2f.

This does not do anything yet, but will allow for gradients later!

The new baked image is a Prekernel and a Kernel baked together now, so
essentially we no longer need to pass the Prekernel as -kernel and the
actual kernel image as -initrd to QEMU, leaving the option to pass an
actual initrd or initramfs module later on with multiboot.

That pattern seems to show up a lot in code written by people that
aren't intimately familiar with the lifetime model of Error and Strings.
This commit makes the compiler detect it and present a more helpful
diagnostic than "garbage string at runtime".

This commit starts adding support for WASI, along with the framework to
implement all the functions (though only a couple are currently
implemented).
|
|
This replaces the inline check for running as root with the common
method exit_if_running_as_root().
|
|
This adds the method exit_if_running_as_root() which checks if the
script is executed under root, and if that's the case exits the script.
|
|
This class can be used to run a task in another thread, and allows the
caller to wait for the task to complete to retrieve any error that may
have occurred.
Currently, it doesn't support functions returning a value on success,
but with some template magic that should be possible. :^)
|
|
coreutils include timeout tool that is going to be used in layout
tests script.
|
|
Previous this ignored typed arrays and ArrayBuffer, hitting the
fallback JS -> C++ conversion case, typically stringifying them.

For the most part no behavior change, except that we now pass
-Wno-implicit-const-int-float-conversion and -Wno-literal-suffix
only to clang and gcc each in both lagom and serenity builds,
while we previously passed them to both in lagom builds (and
passed them to one each in serenity builds). The former is
a clang flag, the latter a gcc flag, but since we also use
-Wno-unknown-warning-option it doesn't really matter.

No behavior change.

This builds simple fuzzing binaries without any oss-fuzz specific
configuration and without any LibFuzzer instrumentation.

In CLDR 42 and earlier, we were able to assume all cldr-localename files
existed for every locale. They now do not exist for locales that don't
provide any localized data. Namely, this is the "und" locale (which is
an alias for the root locale, i.e. the locale we fall back to when a
user provides an unknown locale).
Further, we were previously able to assume that each currencies.json in
cldr-numbers contained all currencies. This file now excludes currencies
whose localized names are the same as the currency key. Therefore, we
now preprocess currencies.json to discover all currencies ahead of time,
much like we already do for languages.json.

None of these are ever null after the VM has been initialized, as proved
by virtually every caller immediately dereferencing the raw pointer.
|
|
Some of these are allocated upon initialization of the intrinsics, and
some lazily, but in neither case the getters actually return a nullptr.
This saves us a whole bunch of pointer dereferences (as NonnullGCPtr has
an `operator T&()`), and also has the interesting side effect of forcing
us to explicitly use the FunctionObject& overload of call(), as passing
a NonnullGCPtr is ambigous - it could implicitly be turned into a Value
_or_ a FunctionObject& (so we have to dereference manually).
|
|
Previously, the condition was reversed, so we would stop immediately on
a file that has at least one working chunk, and we would infinitely loop
on a file with no chunks.

Target GDB is only used for debugging the kernel, which is not relevant
to most people. Starting with 924758c6f8bcf, GDB would always be built
as part of the toolchain if the user didn't have it installed. This is
unnecessary.
This commit adds a separate script for building GDB, which the user
needs to explicitly invoke. A message is added to Meta/debug-kernel.sh
which alerts the user to this fact.

When we had 32 bit support in the OS kernel and userland, the very bare
minimum CPU we supported was Pentium 3, but now the CPU is just required
to support x86-64 long mode to be supported, so the exact model is not
very important.
I chose the QEMU64 virtual CPU model, because the whole concept of the
QEMU ISA-PC machine is that it checks how the kernel handles arbitrarily
old hardware setup.

This implements the IDL for these types and some event handling around
them.

Loads of changes that are tightly connected... :/
* Change lambdas to static functions
* Add spec docs to those functions
* Keep the current scope around as a parameter
* Add wrapping classes for some Certificate members
* Parse ec and ecdsa data from certificates

Previously, we would unconditionally build GDB from source for the
AArch64 toolchain. This commit makes it possible to use the system's
`gdb` binary if it supports the architecture, or `aarch64-elf-gdb` if
such a package is installed.
An `aarch64-elf-gdb` package will be available through Homebrew once
this PR is merged: https://github.com/Homebrew/homebrew-core/pull/127323

This solves the longhands must be initialized before shorthands
problem by just initializing the value when it is first requested.
This will be needed for background-position-x/y which is a longhand
of a longhand, which otherwise breaks the longhands before shorthands
rule.

This avoids a bash complaint for the new option

This makes sure that symbol names are demangled in the assembly view.
