Hi, in order to use a few functions in the transformation phase of IPA-CP without computing the whole struct ipa_node_params for the current function, the following patch makes those functions (or their _1 versions) use just the vector they need.
Bootstrapped and tested on x86_64-linux, needed for the aggregate IPA-CP. OK for trunk? Thanks, Martin 2012-10-31 Martin Jambor <mjam...@suse.cz> * ipa-prop.c (ipa_get_param_decl_index_1): New function. (ipa_get_param_decl_index): Just call ipa_get_param_decl_index_1. (ipa_populate_param_decls): Accept descriptors parameter rather than the whole info. (load_from_unmodified_param): Likewise. (ipa_load_from_parm_agg_1): Likewise. (ipa_load_from_parm_agg): Extract descriptors from info. (compute_complex_assign_jump_func): Likewise. (ipa_analyze_indirect_call_uses): Likewise.
