These are going to be included in the ECMA-262 AOs once Temporal reaches
stage 4. There's no need to keep them in the Temporal namespace. Some
upcoming Temporal editorial changes will get awkward without this patch.
We were passing types like ISODate by reference so that they could be
used as forward-declarations. But after commit 021a5f4ded, we now have
their full definitions anywhere they're needed. So let's pass ISODate by
value everywhere consistently - it is only 8 bytes.
Currently, AbstractOperations.h needs to include Time.h for the Time
structure. Soon, Time.h will need to include AbstractOperations.h for
structures defined there. To avoid a circular include, let's put the
ISO types into their own file, so that AO.h does not need to include
any JS type header.
Our BigInt implementation can store the negativity of the division
result in either the quotient or the remainder. This is exposed by an
upcoming prototype, which will reach this division with:
-432000000000000 / 86400000000000000000000
Which has the BigInt division result:
quotient = 0
remainder = -432000000000000
(Our old Temporal implementation also had this bug).
We now have the Temporal facilities to implement the Date AOs which
parse UTC offset strings using the ISO8601 parser. This patch updates
those AOs and their callers in accordance with the Temporal spec.
This also includes a stubbed Temporal.Duration.prototype.
Until we have re-implemented Temporal.PlainDate/ZonedDateTime, some of
Temporal.Duration.compare (and its invoked AOs) are left unimplemented.
Our Temporal implementation is woefully out of date. The spec has been
so vastly rewritten that it is unfortunately not practical to update our
implementation in-place. Even just removing Temporal objects that were
removed from the spec, or updating any of the simpler remaining objects,
has proven to be a mess in previous attempts.
So, this removes our Temporal implementation. AOs used by other specs
are left intact.
Resulting in a massive rename across almost everywhere! Alongside the
namespace change, we now have the following names:
* JS::NonnullGCPtr -> GC::Ref
* JS::GCPtr -> GC::Ptr
* JS::HeapFunction -> GC::Function
* JS::CellImpl -> GC::Cell
* JS::Handle -> GC::Root
