ee21e39044 [log] report code relocation through CodeEventHandler
Also report code relocation events through the public CodeEventHandler
API, so that embedders can expose this information to external
profilers, allowing those profilers to correctly translate function
names even after they were relocated.

6ebc808a9b [wasm][anyref] fix decoding of table index immediates
Before dd6f4d4f4c, this function was reading a single u8 and verifying
that it was 0x00. The referenced commit dropped this check as part of
implementing decoding for table.get, but neglected to change the read type
to u32v, which is the specified type of this immediate. Fix that.

3b8c624bda GCC: explicitely instantiate JSObject::ApplyAttributesToDictionary for NumberDictionary
elements.cc invokes ApplyAttributesToDictionary using NumberDictionary as its template
parameter. But the declaration of the template method is in js-object.cc, so nobody
can actually compile the version for number dictionary. This is fixed requesting
explicit instantiation for NumberDictionary.

This was breaking GCC build.

348cc6f152 Improve toString(radix) for doubles near zero
Currently, Number.prototype.toString(radix) often fails to produce the
least significant bit for doubles near zero. For example, for the
minimum double, 5e-324, toString(2) produces "0". This means that a
user cannot reliably get the exact binary or hexdecimal value of a
double from JavaScript using toString.

This patch makes a slight amendment to the DoubleToRadixCString
function, so that doubles where the gap to the next double is 5e-324
(i.e. doubles less than 2**-1021), are represented exactly in binary and
other power-of-two bases, and close to exactly otherwise. It results
in Number.prototype.toString producing the correct binary value for all
doubles.

450ada04b2 ppc: Fix incorrect ABI detection

but this is not sufficient to properly detect cases in

Update these checks to use additionally use the _CALL_ELF
macro in order to properly handle such cases.

This issue was initially discovered by the Adélie Linux team.

2d08967d4a [coverage] Extend SourceRangeAstVisitor for throw statements
The SourceRangeAstVisitor has custom logic for blocks ending with a
statement that has a continuation range. In these cases, the trailing
continuation is removed which makes the reported coverage ranges a bit
nicer.

throw Error('foo') consists of an ExpressionStatement, with a
Throw expression stored within the statement. The source range itself
is stored with the Throw, not the statement.

We now properly extract the correct AST node for trailing throw
statements.

385aa80aff Correct removal of redundant moves
The logic for removing while iterating is non-standard and
a left over from a previous index based loop. This patch
replaces it with a standard erase based version.

This fixes a runtime crash with MSVC that invalidates the
iterator and then asserts. This also makes the code safe
in case the last move can be redundant.

f781f522af Re-detect the host time zone if requested by an embedder
Add an enum argument to DateTimeConfigurationChangeNotification to
control whether or not to redetect the host time zone. The default value
kSkip doesn't cause redetecting so that callers do not need to change if
they want the current behavior (e.g. Chromium).

Note that the host time zone detection does not work when v8 is run
inside a sandbox as in Chromium so that Chromium detects the host time
zone outside the sandbox before calling
DateTimeConfigurationChangeNotification. OTOH, other v8 embedders may
find it more convenient for v8 to do the host time zone detection on
their behalf. In that case, they can call the function with the new
argument set to value kRedetect.

Test:
With PHP+V8Js on linux, execute:
php -r '
  putenv("TZ=Europe/Helsinki");
  $v8 = new V8Js();
  $v8->executeString("print((new Date(0)).toString()+\"\\n\");");
  putenv("TZ=America/New_York");
  $v8->executeString("print((new Date(0)).toString()+\"\\n\");");'

74571c80a9 Fix preview of set entries
Set entries return an array with the value as first and second entry.
As such these are considered key value pairs to align with maps
entries iterator.
So far the return value was identical to the values iterator and that
is misleading.

This also adds tests to verify the results and improves the coverage
a tiny bit by testing different iterators.

c7c0e110f5 [typedarray] Use fast path for Float32Array.from(float_64_array) and similar
Currently, because the source float_64_array has an iterator, it hits
the code in the "check_iterator" section of TypedArrayFrom which calls
IterableToList. This builds a temporary PACKED_ELEMENTS array (and boxes
all of the numeric values as HeapNumbers), then uses this as the source
array.

This patch checks if the source array is a TypedArray, and if the iterator
is the built-in one (where we know the iterator's behaviour). If both are
true then it bypasses the creation of this temporary array and uses the
original TypedArray as the source.

This allows it to take advantage of the existing fast code for copying one
typed array to another.

a8f6869177 [debug] Fully implement Debug::ArchiveDebug and Debug::RestoreDebug.
I have a project that embeds V8 and uses a single `Isolate` from multiple
threads. The program runs just fine, but sometimes the inspector doesn't
stop on the correct line after stepping over a statement that switches
threads behind the scenes, even though the original thread is restored by
the time the next statement is executed.

After some digging, I discovered that the `Debug::ArchiveDebug` and
`Debug::RestoreDebug` methods, which should be responsible for
saving/restoring this `ThreadLocal` information when switching threads,
currently don't do anything.

This commit implements those methods using MemCopy, in the style of other
Archive/Restore methods in the V8 codebase.

d683fd7dd6 [asmjs] Fix parsing hex numeric literals ending with 'e'.
When parsing a numeric literal in a line like "a=0x0e+b|0;",
currently the scanner consumes the "e+" part (as it thinks
it's the start of an exponent).
In the ECMAScript lexical grammar HexIntegerLiteral cannot
contain exponents, which means the '+' character should be
parsed as a binary operator.

8d4572a22b [builtins] Add %IsTraceCategoryEnabled and %Trace builtins
Adds the builtin Trace and IsTraceCategoryEnabled functions
exposed via extra bindings. These are intended to use by
embedders to allow basic trace event support from JavaScript.

```js
isTraceCategoryEnabled('v8.some-category')

trace('e'.charCodeAt(0), 'v8.some-category',
      'Foo', 0, { abc: 'xyz'})
```
