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.
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 924758c6f8, 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.
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 makes it easy to compare the performance of Serenity's
deflate implementation to the host system implementation.
On my M1 Max MBP:
% time gunzip -c \
/Users/thakis/Downloads/trace_bug.json.gz > /dev/null
takes between 0.064s and 0.082s.
% time Build/lagom/gunzip -c \
/Users/thakis/Downloads/trace_bug.json.gz > /dev/null
on the other hand takes 4 seconds.
(That .gz file is a 5.8M file -- the largest .gz file that happend to be
in my Downloads folder.)
This is an implementation that tries to follow the spec as closely as
possible, and works with Qemu's Intel HDA and some bare metal HDA
controllers out there. Compiling with `INTEL_HDA_DEBUG=on` will provide
a lot of detailed information that could help us getting this to work
on more bare metal controllers as well :^)
Output format is limited to `i16` samples for now.
