The existing version will overwrite the existing writable flag with false even in the case where no new value is given and the existing writable flag is true. The reason for the issue is that there is no check to see if the provided descriptor actually has a writable attribute. This causes us to use the default value (false) even in the case where nothing was provided. In addition, the existing tests makes wrong assumptions (that writable is always set to false if not provided) and has been changed to follow the specification.

The full compiler is now complete on ARM as well. The syntax checker is still used to determine whether to use it for top level code or not during normal execution. When debugging is enabled all code will be compiled with the full compiler. This change removes the temporary flag --force-full-compiler and now the flag --always-full-compiler enables the full compiler for all code on all platforms. This also fixes building on Intel platform without debugger support (ENABLE_DEBUGGER_SUPPORT not defined) and adds full check for the full compiler for lazily compiled code.

- New сardmarking write barrier handles large objects and normal objects in a similar fashion (no more additional space for pointer tracking is required, no conditional branches in WB code). - Changes to enable oldspaces iteration without maps decoding: -- layout change for FixedArrays: length is stored as a smis (initial patch by Kevin Millikin) -- layout change for SharedFunctionInfo: integer fields are stored as smi on arm, ia32 and rearranged on x64. -- layout change for String: meaning of LSB bit is fliped (1 now means hash not computed); on x64 padding is added. -- layout of maps is _not_ changed. Map space is currently iterated in a special way.

Currently one can only define accessors on object templates. This patch allows to create accessors on the fly. These accessors could control access to elements as well. This element support is somewhat rudimentary and may require future work (for example, we probably don't want to convert index into a string.)

Noticing that the only difference between samevalue and strict equality is on numbers we can simplify SameValue. The old version did not return a correct answer if called on two strings since StringEquals (from runtime.cc) returns an answer that is the negated value (if treated as a boolean).

Changing ScriptData API to serialize its internal representation to a const char* array. This decouples the API from the internal representation and avoids the need for callers to serialize themselves. As a side-effect, ScriptData::New() no longer assumes ownership of its input. This shouldn't matter as typical usage patterns for the old API would have required a copy prior to calling ScriptData::New().

Object.defineProperty with empty property descriptor. The issue is fixed by implementing step 5 and 6 from DefineOwnProperty in the specification (ES5 8.12.9). This also fixes a bug in SameValue when used on boolean values (it would priorly return a number - not a boolean).

The full compiler will now be used for all code compiler when debugging is active. As the code generated by the full compiler is much simpler it will be easier to make debugging work better when using that code. To ensure that all code debugged is from the full compiler all functions will have to be recompiled when starting debugging. Initialing debugging already turns off the code cache.
