PUBLIC COMMENTS

Problem:
AddPNode::Ideal() may replace AddP node with CastX2P node
for a raw memory reference. EA code does not check such case.

Solution:
Remove the assert.
                                     

EVALUATION

EA should ignore raw memory operations.
                                     

EVALUATION

Just a backtrace and a dump of addr:
