Member Function Documentation

get_param_index()

int ipcp_transformation::get_param_index	(	const_tree	fndecl,
		const_tree	param ) const

Given PARAM which must be a parameter of function FNDECL described by THIS,
return its index in the DECL_ARGUMENTS chain, using a pre-computed
DECL_UID-sorted vector if available (which is pre-computed only if there are
many parameters).  Can return -1 if param is static chain not represented
among DECL_ARGUMENTS.

maybe_create_parm_idx_map()

void ipcp_transformation::maybe_create_parm_idx_map

(

tree

fndecl

)

Assuming THIS describes FNDECL and it has sufficiently many parameters to
justify the overhead, create a DECL_UID-sorted vector to speed up mapping
from parameters to their indices in DECL_ARGUMENTS chain.
