Method Details

[hide private]

init(self, name, filename, args=`()`, optimized=0, klass=None)
(Constructor)

Overrides: FlowGraph.__init__

computeStackDepth(self)

Compute the max stack depth.

Approach is to compute the stack effect of each basic block. Then find the path through the code with the largest total effect.

_lookupName(self, name, list)

Return index of name in list, appending if necessary

This routine uses a list instead of a dictionary, because a dictionary can't store two different keys if the keys have the same value but different types, e.g. 2 and 2L. The compiler must treat these two separately, so it does an explicit type comparison before comparing the values.

getConsts(self)

Return a tuple for the const slot of the code object

Must convert references to code (MAKE_FUNCTION) to code objects recursively.
