Fix edge case in stack trace formatting. · 7c2a1346

yangguo@chromium.org authored May 24, 2013

Bug description: in strict mode, null as receiver is not implicitly converted
to the global object, so that when formatting the stack trace, the receiver of
the stack frame is null. The IS_OBJECT check returns true for null, but
%GetDataProperty expected a JSObject, which results in a failed RUNTIME_ASSERT.

titzer@chromium.org authored May 24, 2013

Introduce ObjectAccess, which is used by LoadNamedField and StoreNamedField to denote what parts of an object are referred to by a given load or store. Refactor HGraphBuilder to use ObjectAccess, which removes the need to manually set GVN flags and simplifies the code as well.

Make Object.freeze fast · 36e91242

verwaest@chromium.org authored May 23, 2013

This patch both speeds up the freeze operation itself, but also
allows properties to remain in fast mode. Objects with non-empty
elements backing stores still end up with slow elements.

Relanding r14758 and r14759 with fix for Test262: only mark properties
and elements READ_ONLY if they are not JS setter/getters. Tightened up
tests to assert frozen-ness, and added targeted tests for the new code
(covering accessors).
