We have been dancing around circular dependencies between LibCore and
generated sources. For example, LibURL currently cannot depend on
LibUnicode because the LibUnicode generators depend on LibCore, and
LibCore depends on LibURL. LibTimeZone is in a similar situation.
To alleviate this, we can define the minimal sources that the code
generators need as an object library. This will allow the generators to
depend on this library, rather than the full LibCore.
Since the introduction of `AbortSignal::any()`, the specification says
`AbortSignal::create_dependent_abort_signal()` should be used where
`AbortSignal::follow` was previously.
We don't want to always invoke the .play() method if an animation is
relevant and had a play state of running, as the play state is
essentially just "paused" or "not paused". We replace that relevancy
check with the inverse of the pause check so we don't constantly call
.play() on animations that are finished.
Also duplicates and moves the temporary context into both blocks, since
most of the time neither condition will be true.
Rather than trying to store a Handle to a WebIDL::BufferSource, let's
look ahead to what the spec wants us to do with this field and get a
copy of the bytes held by the buffer source right away.
This is achieved by moving ClauseHeader::{AbstractOperation,Accessor,
Method} to Function.h itself and storing them in FunctionDeclaration.
This commit also introduces QualifiedName class that is used to store
function's name split by '.' (just like it appear in the spec).
This simple delay loop uses the time CSR to wait for the given amount
of time. The tick frequency of the CSR is read from the
/cpus/timebase-frequency devicetree property.
Instead, rewrite the region page fault handling code to not use
PageFault::type() on RISC-V.
I split Region::handle_fault into having a RISC-V-specific
implementation, as I am not sure if I cover all page fault handling edge
cases by solely relying on MM's own region metadata.
We should probably also take the processor-provided page fault reason
into account, if we decide to merge these two implementations in the
future.
This commit also removes the unnecessary user_sp RegisterState member.
We never use the kernel stack pointer on entry, so we can simply always
store the stack pointer of the previous privilege mode in sp.
Also remove the sp member from mcontext, as RISC-V doesn't have a
dedicated stack pointer register.
sp is defined to be x2 (x[1] in our case) by the ABI.
I probably accidentally included sp while copying the struct from
aarch64.
sepc has to be incremented before the call to syscall_handler,
as we otherwise would return to the ecall instruction, resulting in an
infinite trap loop.
We can't increment it after syscall_handler, as sepc might get changed
while handling the syscall.
