You need to get at the function structure from the cgraph node with
DECL_STRUCT_FUNCTION (cgraph_node->decl). Then you can use one of the
CFG accessors like basic_block_info_for_function().
For functions to which DECL_STRUCT_FUNCTION (cgraph_node->decl) != 0,
I'm always getting
VARRAY_ACTIVE_SIZE(basic_block_info_for_function(DECL_STRUCT_FUNCTION
(cgraph_node->decl))) == 0.
Is this normal? It seems there are no basic blocks set for the
functions. Probably my pass is being run before the bbs are created?
