df6f0b2ee9 Bug 554955: Give blocks and call objects unique shapes when they have parents that may be extended with new bindings. r=jorendorff 
The comments for js::Bindings::extensibleParents explain why this is necessary.

AssertValidPropertyCacheHit should have been catching this bug, but for
reasons I don't understand, it is restricted from checking this case. This
patch extends it to assert when the bug is detected.

I've gathered the infallible parts of the initialization for Call objects
and cloned block objects into their own functions.

de75b9fa19 Bug 537873: Add a 'strict' argument to C++ property setter functions. r=brendan 
This changes the type of setters to JSStrictPropertyOp, which is just like
JSPropertyOp except that it takes a 'JSBool strict' argument. Most of the
patch is introducing distinct types and using the appropriate stubs.

The following are left for subsequent patches:

x Similar fixes to the browser outside SpiderMonkey.

x Actually *using* the newly available strictness information. This patch
  should have no user-visible effect. I didn't want the interesting stuff
  to get lost in this noise.

Fix a problem where we weren't marking functions created by |new Function| as accepting a primitive this value when their body was strict mode, by removing the duplicative bit that was being checked. r=dmandelin 2010-12-22 18:05:07 -05:00
