This commit has no behavior changes.
In particular, this does not fix any of the wrong uses of the previous
default parameter (which used to be 'false', meaning "only replace the
first occurence in the string"). It simply replaces the default uses by
String::replace(..., ReplaceMode::FirstOnly), leaving them incorrect.
This aligns it with the spec again, it was clarified that the additional
range check before ArrayCreate is intentional:
https://github.com/tc39/proposal-change-array-by-copy/issues/94
Also cast the final variable to an u64 instead of size_t after we have
determined that it is safe to do so, as that's what Array::create()
takes now.
This doesn't matter per se as the value is immediately validated to be
in the 0 to 2^32 - 1 range, but it avoids having to cast a number that
potentially doesn't fit into a size_t into one at the call site. More
often than not, array-like lengths are only validated to be <= 2^52 - 1,
i.e. MAX_SAFE_INTEGER.
This is fully backwards compatible with existing code as a size_t always
fits into an u64, but an u64 might not always fit into a size_t.
This also allows constructing from other integral types like u64, which
would have been ambiguous before (at least on i686):
```
error: call of overloaded 'Value(u64&)' is ambiguous
note: candidate: 'JS::Value::Value(i32)'
175 | explicit Value(i32 value)
| ^~~~~
note: candidate: 'JS::Value::Value(unsigned int)'
164 | explicit Value(unsigned value)
| ^~~~~
note: candidate: 'JS::Value::Value(long unsigned int)'
153 | explicit Value(unsigned long value)
| ^~~~~
note: candidate: 'JS::Value::Value(double)'
141 | explicit Value(double value)
| ^~~~~
```
The implementation no longer matches the spec text, but I believe that's
a bug anyway. No point in allowing array lengths up to 2^53 - 1 when the
ArrayCreate AO rejects anything above 2^32 - 1.
If the for loop's body is not block terminated, we will generate a Jump
to the end block which will block terminate the body. Then, we ended
the lexical variable scope if needed. However, since the body is now
block terminated, the "LeaveLexicalEnvironment" instruction that is
generated by end_variable_scope is now dropped on the floor.
This fixes this by moving it to the beginning of the end block.
Previously we only did this if the body block was not terminated.
If it was, all future codegen would happen in this block terminated
body block until another switch occurred, dropping all generated
instructions in this time on the floor.
This allows `import "./foo"` to succeed, even if the file is actually
called `foo.js`. IDEs commonly exclude file extensions in auto-imports.
Closes#14364.
This is already the parameter name of Core::File::open() and
VM::get_stored_module() - both of which this is passed to - as well as
the member name of the Module class.
Use the newly added TypedArrayBase::intrinsic_constructor() instead to
get the required constructor from the global object.
Also add spec comments while we're here.
