74ec6b9f20 Bug 1030400 - Add sym to the 32 bit big endian branch. r=jorendorff 2014-06-25 18:48:00 +02:00

aa5af229d2 Bug 645416, part 3 - Symbol layout and GC support for allocating them. r=terrence. 
Layout: js/src/vm/Symbol.h defines the new class JS::Symbol. JS::Symbol is the
same size as JSString on all platforms, because the allocator does not support
smaller allocations.

Allocation: Since the purpose of symbols is to serve as property keys, they are
always allocated in the atoms compartment.

We take a lock when allocating. This could probably be replaced with a
main-thread-only assertion. However, if atom allocation is not already a
bottleneck, symbol allocation probably never will be.

Symbols are given their own finalize-class in the GC. This means we allocate a
page per zone for symbols, even though they are only ever allocated in the
atoms zone. Terrence thought this could be easily fixed later. It should be; we
never touch the page, but a 32-bit virtual address space does not just have
infinite pages to spare.

A jsapi-test exercises the new symbol allocation code. A few oddities in
jsapi-tests are fixed in passing.

Discussion after review led to some new assertions about minimum object size in
AllocateObject and AllocateNonObject.

2e4bca5600 Bug 645416, part 2 - Add support for symbols to JS::Value. r=luke. 
The API for symbol Values is much like the API for strings.

The implementation behind all this is in a later patch. Here, a class
JS::Symbol is declared, but not defined anywhere yet.

The constants being deleted from js/public/Value.h probably haven't been used
since Tracemonkey days.

63903fca62 Bug 645416, part 1 - Add an enum for symbols to JSValueType. r=nbp. 
JSVAL_TYPE_SYMBOL is inserted between STRING and NULL, rather than added at the
end, in order to preserve all the inequality relations on JSValueTypes used
throughout Value.h. (Search the header for the operators < > <= >=.)

Otherwise, this pretty much just works. Some details of Ion snapshot layout
had to change to accommodate 4-bit types.
