[Python-Dev] Suggest reverting today's checkin (recursive constant folding in the peephole optimizer) (original) (raw)

One note on the patch: it allocates an extra stack which is dynamically grown; but there is no unittest to exercise the stack-growing code.

Isn't this doing it?

1.20 + # Long tuples should be folded too. 1.21 + asm = dis_single(repr(tuple(range(10000)))) 1.22 + # One LOAD_CONST for the tuple, one for the None return value 1.23 + self.assertEqual(asm.count('LOAD_CONST'), 2) 1.24 + self.assertNotIn('BUILD_TUPLE', asm)
