We were unconditionally trying to update it in the interrupt, which
would depend on the timer interrupt not being received too soon after
the timers are initialized (before the time page was initialized),
which was the case when using HPET timers via the ACPI tables, but not
when using the PIT when ACPI was disabled.
Removes the UnsignedBigInteger overloads of
SignedBigInteger::binary_{and,or,xor}(). They're now unused, and they
also didn't work when *this was negative.
We went through some trouble to make & and | work right. Reimplement ^
in terms of & and | to make ^ work right as well.
This is less fast than a direct implementation, but let's get things
working first.
Similar to the bitwise_and change, but we have to be careful to
sign-extend two's complement numbers only up to the highest set bit
in the positive number.
Bitwise and is defined in terms of two's complement, so some converting
needs to happen for SignedBigInteger's sign/magnitude representation to
work out.
UnsignedBigInteger::bitwise_not() is repurposed to convert all
high-order zero bits to ones up to a limit, for the two's complement
conversion to work.
Fixes test262/test/language/expressions/bitwise-and/bigint.js.
Bitwise operators are defined on two's complement, but SignedBitInteger
uses sign-magnitude. Correctly convert between the two.
Let LibJS delegate to SignedBitInteger for bitwise_not, like it does
for all other bitwise_ operations on bigints.
No behavior change (LibJS is now the only client of
SignedBitInteger::bitwise_not()).
Rather than using a hard-coded list from AK::UnicodeUtils, LibUnicode
contains the up-to-date official names and contains abbreviations for
more control code points.
Performance of string concatenation regressed in a57e2f9. That commit
iterates over the LHS string to find the last code unit, to check if it
is a high surrogate. Instead, first look at the 3rd-to-last byte in the
UTF-8 encoded string to check if it is a 3-byte code point; then decode
just those bytes to check if we have a high surrogate. Similarly, check
the first 3 bytes of the RHS string to check if we have a low surrogate.
Only a generic struct definition was present for NVMeSubmission. To
improve type safety and clarity, added an union of NVMeSubmission
structs that are applicable to the command being submitted.
The CAP.TO is 0 based. Even though I don't see that mentioned in the
spec explicitly, all major OSs such as Linux, FreeBSD add 1 to the
CAP.TO while calculating the timeout.
IO::delay was added as a lazy alternative to looping with a timeout
error if the condition was not satisfied. Now that we have the
wait_for_ready function, remove the delay in the reset and start
controller function.
We can re-use the logic used for automatic scrolling in AbstractView
when we're doing rubberband scrolling in IconView. This removes some
duplicated code.
This highlighter just syntax highlights the commented lines in your git
commit message. It could potentially be enhanced to handle the rebase
UI or other more advanced cases in the future.
The new `use_fresh_config_sub` option puts the config.sub in the root of
the tree, but `readline` puts it in the `support/` folder. So we need to
tell the ports infrastructure to place the file in that folder.
In the following use case:
"\ud834" + "\udf06"
We were previously combining these as two individual code points. When
concatenating strings, we must take care to combine the high surrogate
from the left-hand side with the low surrogate from the right-hand side.
This function is used quite a bit during the lighting calculations, so
it's a bit cleaner having it in a centralized spot instead of just
arbitrarily calling `dot()` with numerous `FloatVector3` conversions.
This was already implemented and duplicated across the
String.prototype.trim{, Start, End} methods, so this simply extracts it
into a separate method that can also be used by other users.
This implements an 8-bit front stencil buffer. Stencil operations are
SIMD optimized. LibGL changes include:
* New `glStencilMask` and `glStencilMaskSeparate` functions
* New context parameter `GL_STENCIL_CLEAR_VALUE`
