Detailed Description

Apply reduction rules to an expr

reduction_rules: list of ordered reduction rules

List of function representing reduction rules
Function API:
reduction_xxx(self, node, lvl=0)
with:
* node: the ExprNode to qualify
* lvl: [optional] the recursion level
Returns:
* None if the reduction rule is not applied
* the resulting information to store in the ExprNode.info

allow_none_result: allow missing reduction rules

Member Function Documentation

apply_rules()

def miasm.expression.expression_reduce.ExprReducer.apply_rules	(		self,
			node,
			lvl = 0,
		**	kwargs
	)

Find and apply reduction rules to @node

@node: ExprNode to analyse
@lvl: actuel recursion level

Here is the caller graph for this function:

categorize()

def miasm.expression.expression_reduce.ExprReducer.categorize	(		self,
			node,
			lvl = 0,
		**	kwargs
	)

Recursively apply rules to @node

@node: ExprNode to analyze
@lvl: actual recursion level

Here is the call graph for this function:

Here is the caller graph for this function:

expr2node()

def miasm.expression.expression_reduce.ExprReducer.expr2node	(		self,
			expr
	)

Build ExprNode mirror of @expr

@expr: Expression to analyze

Here is the call graph for this function:

Here is the caller graph for this function:

reduce()

def miasm.expression.expression_reduce.ExprReducer.reduce	(		self,
			expr,
		**	kwargs
	)

Returns an ExprNode tree mirroring @expr tree. The ExprNode is
computed by applying reduction rules to the expression @expr

@expr: an Expression
