Hi Hannes,
Here is the change we've discussed. I'll follow up shortly with binary op
strings also ports.
thx,
--Michael
Description:
Emit mementos in crankshaft. Right now, it's controlled by asking an
allocation site if it's "undecided" yet. A flag
"pretend-pretenuring-uncertainty" can be used to force all allocation
sites to masquerade as undecided for testing purposes.
Crankshaft mementos can be turned on for:
* Array and object literals
* Array and object constructor calls (if pretenuring_call_new is
turned on)
Not yet implemented is:
* Strings in binary ops.
