While trying to port to Clang we found that the functions as
implemented didn't actually work, and replacing them with a blatantly
broken function also did not break the tests on the GCC build. It
turns out we've been testing GCC's builtins by many tests. This
removes the use of builtins for LibM's tests (so we test the whole
function). It turns off the denormal test for scalbn (which was not
implemented) and comments out the tgamma(0.5) test which is too
inaccurate to be usable (and too complicated for me to fix). The gamma
function was made accurate for all other test cases, and asin received
two more layers of Taylor expansion to bring it within error margin
for the tests.
We should never request a regions removal that we don't currently
own. We currently assert this everywhere else by all callers.
Instead lets just push the assert down into the RedBlackTree removal
and assume that we will always successfully remove the region.
File Manager and Spreadsheet had an inconsistent order relative
to other apps (they had a copy-cut-paste order, where every other app
had a cut-copy-paste order).
Today the profile viewer timeline view has a static size, which is
computed as half the height of the window given it has two root widgets.
Instead the timeline view should shrink to only consume the size that
each process timeline consumes.
The previous implementation was too generic, and would cause conflicting
operator overload errors when included in certain code paths. Fix this
by restricting the template parameters to types which have the same
member names as `struct timespec`.
This completely changes how HTMLTokens store their data. Previously,
space was allocated for all token types separately. Now, the HTMLToken's
data is stored in just a String, two booleans and a Variant.
This change reduces sizeof(HTMLToken) from 68 to 32. Also, this reduces
raw tokenization time by around 20 to 50 percent, depending on the page.
Full document parsing time (with HTMLDocumentParser, on a local HTML
page without any dependency files) is reduced by between 4 and 20
percent, depending on the page.
Since tokenizing HTML pages can easily generated 50'000 tokens and more,
the storage has been designed in a way that avoids heap allocations
where possible, while trying to reduce the size of the tokens. The only
tokens which need to allocate on the heap are thus DOCTYPE tokens (max.
1 per document), and tag tokens (but only if they have attributes). This
way, only around 5 percent of all tokens generated need to allocate on
the heap (except for StringImpl allocations).
Since all interaction with the HTMLToken class now happens over getters
and setters, there is no more need for HTMLTokenizer and
HTMLDocumentParser to have direct access to the members.
This is in preparation for an upcoming storage change of HTMLToken. In
contrast to the other token types, the accessor can hand out a mutable
reference to allow users to change parts of the DoctypeData easily.
Previously, HTMLToken would expose the Vector<Attribute> directly to
its users. In preparation for a future change, all users now use
implementation-agnostic APIs which do not expose the Vector directly.
Pressing tab would focus on the demo widgets instead of switching
between the combo box and color input field. Instead set the focus
policy to NoFocus for all the widgets.
On x86_64 GCC implements va_list as an array. This makes the syntax
for taking a pointer to it break & crash. The workaround / solution is
to create a copy. Since va_list is a tiny struct referencing the
actual varargs, this is little overhead (especially compared to
va_args itself)
That can happen because of anyone sending the process a SIGCONT.
Fixes an issue where continuing a process launched by the shell from
the System Monitor would cause the shell to spin on waitpid().
* wasm: Don't try to print the function results if it traps
* LibWasm: Inline some very hot functions
These are mostly pretty small functions too, and they were about ~10%
of runtime.
* LibWasm+Everywhere: Make the instruction count limit configurable
...and enable it for LibWeb and test-wasm.
Note that `wasm` will not be limited by this.
* LibWasm: Remove a useless use of ScopeGuard
There are no multiple exit paths in that function, so we can just put
the ending logic right at the end of the function instead.
