This API was a mostly gratuitous deviation from POSIX that gave up some
portability in exchange for avoiding the occasional strlen().
I don't think that was actually achieving anything valuable, so let's
just chill out and have the same open() API as everyone else. :^)
The coarse clocks in time.h are a linux extension that we've adopted.
MacOS and the BSDs don't have it, so we need an alias in a platform
header for Lagom builds.
clang-format seems to barf on these attributes, to make it easier to
use these attributes and have clang-format not mangle the following code
we can hide them behind a macro so clang-format doesn't have to handle it.
This stopped working quite some time ago due to Clang losing track of
typestates for some reason and everything becoming "unknown".
Since we're primarily using GCC anyway, it doesn't seem worth it to try
and maintain this non-working experiment for a secondary compiler.
Also it doesn't look like the Clang team is actively maintaining this
flag anyway. So good-bye, -Wconsumed. :/
Clang keeps whining that NonnullFooPtrs are in "unknown" state and I'm
not sure how to resolve that right now. Disable the checking until we
can figure it out.
AK::Bitmap is extended with find_next_range_of_unset_bits().
The function is implemented using count_trailing_zeroes_32(), which is
optimized on many platforms, that gives a huge performance boost.
Functions find_longest_range_of_unset_bits() and find_first_fit() are
implemented with find_next_range_of_unset_bits(). According to
benchmarks, they are 60-100% faster.
As suggested by Joshua, this commit adds the 2-clause BSD license as a
comment block to the top of every source file.
For the first pass, I've just added myself for simplicity. I encourage
everyone to add themselves as copyright holders of any file they've
added or modified in some significant way. If I've added myself in
error somewhere, feel free to replace it with the appropriate copyright
holder instead.
Going forward, all new source files should include a license header.
Clang loses the typestate when passing NonnullRefPtr's via lambda captures.
This is unfortunate, but not much we can do about it. Allowing ptr() makes
it possible to use captured NonnullRefPtrs as you'd expect.
You can currently use this to detect the CPU architecture like so:
#if ARCH(I386)
...
#elif ARCH(X86_64)
...
#else
...
#endif
This will be helpful for separating out architecture-specific code blocks.
