cpython-lru_cache-weakref: Python/ceval.c annotate

annotate Python/ceval.c @ 28716:ab4fbf8ebab3 legacy-trunk

Improved the bytecode optimizer. * Can now test for basic blocks. * Optimize inverted comparisions. * Optimize unary_not followed by a conditional jump. * Added a new opcode, NOP, to keep code size constant. * Applied NOP to previous transformations where appropriate. Note, the NOP would not be necessary if other functions were added to re-target jump addresses and update the co_lnotab mapping. That would yield slightly faster and cleaner bytecode at the expense of optimizer simplicity and of keeping it decoupled from the line-numbering structure.

c24a23b1f198 Added implementation notes for [re]set_exc_info(). Guido van Rossum <guido@python.org> parents: 28086 diff changeset	2691
c24a23b1f198 Added implementation notes for [re]set_exc_info(). Guido van Rossum <guido@python.org> parents: 28086 diff changeset	2692 - Within one frame, sys.exc_ZZZ will hold the last exception caught

c24a23b1f198 Added implementation notes for [re]set_exc_info(). Guido van Rossum <guido@python.org> parents: 28086 diff changeset	2700 bullet was for backwards compatibility: it was (and is) common to
