This change is supposed to solve the problem that currenty when grid
tracks are interleaved with gaps it is impossible to iterate tracks
spanned by a specific grid item. There is a pair of functions:
gap_adjusted_row() and gap_adjusted_column() but they won't work
when it comes to items spanning > 1 track.
Separating gaps from tracks is going to make it possible to iterate
just tracks or both tracks and gaps when it is required. And now tracks
spanned by an item can be accessed by just index without doing any
additional math.
As IFUNC resolvers may call arbitrary functions though the PLT, they can
only be called after the PLT has been populated. This is true of the
`[[gnu::target_clones]]` attribute, which makes a call to
`__cpu_indicator_init`, which is defined in `libgcc_s.so`, through the
PLT.
`do_plt_relocation` and `do_direct_relocation` are given a parameter
that controls whether IFUNCs are immediately resolved. In the first
pass, relocations pointing to IFUNCs are put on a worklist, while all
other relocations are performed. Only after non-IFUNC relocations are
done and the PLT is set up do we deal with these.
No functional changes intended. This is in preparation of a commit that
overhauls how IFUNCs are resolved.
This commit lets us move the implementation of PLT patching from
`DynamicObject` to `DynamicLoader` where all other relocation code
lives. For this, got[2] now stores the loader's address instead of the
object's.
This is the AArch64 equivalent of `R_X86_64_IRELATIVE`, which specifies
a symbol whose address is determined by calling a local IFUNC resolver
function.
The spec says: "The first value gives the width of the corresponding
image, the second value its height. If only one value is given the
second is assumed to be auto."
Fixes#18782
The spec seems to neglect the potential nullity of an image's pending
request in various cases.
Let's protect against crashing and mark these cases with a FIXME about
figuring out whether they are really spec bugs or not.
The expression evaluator is dead code that does nothing but crash on
all paths, as no opcodes are implemented.
Stubbing out the LocListX form fixes a crash while reading DWARF 5
debug data that contains location lists. These are just a new way
to store location expressions, and since we never implemented
expressions, we can just ignore these too.
As far as I can tell this is enough for DWARF 5 to work for us (since
we mainly just use the line tables).
Unwind contexts now remember the lexical and variable environments in
effect when they were created. If an exception is caught, we revert
to those environments in the running execution context.
For `try` statements with a `catch` clause, we were generating *two*
"next" blocks. This meant that not throwing an exception would cause
execution to stop.
Fix this by using the "next" block pointer for the try "entry" and
"handler" blocks.
This fixes an issue where object environments (from `with` statement)
were bypassed by statements like `var x = 1` (for objects with an `x`
property).
Fixes 25 tests in test262. :^)
Rather than setting the src attribute on the HTMLMediaElement, websites
may append a list of HTMLSourceElement nodes to the media element. There
is a series of "try the next source" steps to attempt to fetch/load each
source until we find one that works.
There's no need for this to require a DeprecatedString - the method it
wraps around already only expects a StringView. This allows passing a
String instance without any conversion.
FontEditor will need to clear references to its mutable font in
the future while CharacterMap has no use for the highlights clone,
so let's convert GlyphMapWidget's set_font wrapper into a separate
initialize function for the editor and stop hiding the base function
for others. Setting font null in either ultimately points the map to
the system's default font.
When a width/height constraint is applied to GFC it should set its own
width/height to the sum of track sizes according to the spec.
Changes in layout tests are improvement over what we had before.
We achieve this by adding a new Layout::ImageProvider class and having
both HTMLImageElement and HTMLObjectElement inherit from it.
The HTML spec is vague on how object image loading should work, which
is why this first pass is focusing on image elements.
This patch adds HTML::ImageRequest and HTML::DecodedImageData.
The latter had to use a different name than "ImageData", as there is
already an IDL-exposed ImageData class in HTML.
This makes hovering around on GitHub fast again, as it no longer
believes that the grid-template-areas property keeps changing
when it didn't :^)
Also made to_string() work for calc() values as well, since I stumbled
upon that while debugging this.
The UTF-8 decoder will currently crash if it is provided invalid UTF-8
input. Instead, change its behavior to match that of all other decoders
to replace invalid code points with U+FFFD. This is required by the web.
The completion callback currently only accepts a JavaScriptModuleScript.
The same callback will need to be used for ClassicScript scripts as well
so allow the callback to accept any Script type. The single existing
outside caller already stores the result as a Script.
