Changeset 1864 in webkit for trunk/JavaScriptCore/kjs/function.h

Timestamp:

Message:

Maintain stack of old "arguments" property values for functions
implicitly on the system stack instead of explicitly in the
FunctionImp. This eliminates only a trivial number of GC
allocations (less than 200) but eliminates one of the two cases
where a ListImp * is stored directly, paving the way to separate
List from Value.

• kjs/function.h: Remove argStack, pushArgs and popArgs.
• kjs/function.cpp: (FunctionImp::FunctionImp): Don't initalize argStack. (FunctionImp::~FunctionImp): Remove comment about argStack. (FunctionImp::mark): Don't mark the argStack. (FunctionImp::call): Save old "arguments" property in a Value, where it will be GC-protected, rather than keeping a list, and restore the old value when done executing.
