Member Typedef Documentation

types

detect the first type that is in the typedef list parselib.transforms.typedef_expansion.TypedefExpansion.types = node.children[0]

Definition at line 212 of file typedef_expansion.py.

Constructor & Destructor Documentation

__init__()

parselib.transforms.typedef_expansion.TypedefExpansion.__init__	(		self,
			types )

Reimplemented from parselib.transforms.top_down.TopDown.

__append_to_expandable_var_to_tree()

parselib.transforms.typedef_expansion.TypedefExpansion.__append_to_expandable_var_to_tree ( self, tree, field_name )

private

append the field_name to the expandable variable in tree

Definition at line 316 of file typedef_expansion.py.

__check_stmt_portbinding()

parselib.transforms.typedef_expansion.TypedefExpansion.__check_stmt_portbinding ( self, stmt )

private

Definition at line 585 of file typedef_expansion.py.

__expand_blkassign()

parselib.transforms.typedef_expansion.TypedefExpansion.__expand_blkassign ( self, tree )

private

detects the expandable variable on lhs and rhs and
expand them with the fields

Definition at line 353 of file typedef_expansion.py.

__expand_decl_in_tree_children()

parselib.transforms.typedef_expansion.TypedefExpansion.__expand_decl_in_tree_children ( self, tree, expand_data = None )

private

Definition at line 488 of file typedef_expansion.py.

__expand_helper()

parselib.transforms.typedef_expansion.TypedefExpansion.__expand_helper ( self, portdecl, typeinfo )

private

portdecl is the name:
Tree(outportdecl, [Token(ID, 'dout')])
typeinfo is the real type info:
Tree(htypeinfo, [Tree(htype, [Token(TYPESTR, 'sc_out'), Tree(htype, [Token(TYPESTR, 'fp_t'), 52, 11])])])

Definition at line 71 of file typedef_expansion.py.

__expand_htype()

parselib.transforms.typedef_expansion.TypedefExpansion.__expand_htype ( self, htype )

private

expand non-primitive htype into primitive sub-field type

Definition at line 21 of file typedef_expansion.py.

__expand_portdecltype()

parselib.transforms.typedef_expansion.TypedefExpansion.__expand_portdecltype ( self, tree )

private

The expansion is achieved by first traverse the type subtree to detect the expandable type,
then, any parent path is duplicated
An example of tree:
Tree(portdecltype, [Tree(inportdecl, [Token(ID, 'clk')]), Tree(htypeinfo,
    [Tree(htype, [Token(TYPESTR, 'sc_in'), Tree(htype, [Token(TYPESTR, '_Bool')])])])])
