Bug 45528 – Move JavaScriptCore statistics gathering into JavaScriptCore

• Component: JavaScriptCore
• Status: RESOLVED FIXED

[Stephanie Lewis]

Refactor JavaScriptCore memory statistics so that WebKit doesn't need to know about the JIT and other implementation details of JavaScriptCore.  Necessary to fix PPC build.

This shouldn't be indented.

I think that it's nice to put heap and stack/JIT statistics under a common umbrella. But I don't think that it's good to report both global and per-heap statistics via one call. Can it be split in two?

> +namespace JSC {
> +

This shouldn't be indented.

> +    MemoryStatistics mStats = memoryStatistics(JSDOMWindow::commonJSGlobalData());

We prefer to not abbreviate words - and "m" is a prefix for member variables!

r=me, since we need to fix the build ASAP, but I think that this can be improved a bit later.
