annotate Python/compile.c @ 5181:8a0b80dc6e71 legacy-trunk
Added support for ``if __debug__:'' -- if -O is given, this form is
recognized by the code generator and code generation for the test and
the subsequent suite is suppressed.
One must write *exactly* ``if __debug__:'' or ``elif __debug__:'' --
no parentheses or operators must be present, or the optimization is
not carried through. Whitespace doesn't matter. Other uses of
__debug__ will find __debug__ defined as 0 or 1 in the __builtin__
module.
