Python constant_from_op Examples

Example #1

File: heapcache.py Project: sczfaker/pypy

 def replace_box(self, oldbox, newbox):
     # here, only for replacing a box with a const
     if isinstance(oldbox, FrontendOp) and isinstance(newbox, Const):
         assert newbox.same_constant(constant_from_op(oldbox))
         oldbox.set_replaced_with_const()

Example #2

 def replace_box(self, oldbox, newbox):
     # here, only for replacing a box with a const
     if isinstance(oldbox, FrontendOp) and isinstance(newbox, Const):
         assert newbox.same_constant(constant_from_op(oldbox))
         oldbox.set_replaced_with_const()

Example #3

    else:
        return box
