--- Comment #29 from Martin Jambor <jamborm at gcc dot gnu.org> --- Author: jamborm Date: Wed Mar 1 09:37:27 2017 New Revision: 245805 URL: https://gcc.gnu.org/viewcvs?rev=245805&root=gcc&view=rev Log: [PR 78140] Reuse same IPA bits and VR info 2017-03-01 Martin Jambor <mjam...@suse.cz> PR lto/78140 * ipa-prop.h (ipa_bits): Removed field known. (ipa_jump_func): Removed field vr_known. Changed fields bits and m_vr to pointers. Adjusted their comments to warn about their sharing. (ipcp_transformation_summary): Change bits to a vector of pointers. (ipa_check_create_edge_args): Moved to ipa-prop.c, declare. (ipa_get_ipa_bits_for_value): Declare. * tree-vrp.h (value_range): Mark as GTY((for_user)). * ipa-prop.c (ipa_bit_ggc_hash_traits): New. (ipa_bits_hash_table): Likewise. (ipa_vr_ggc_hash_traits): Likewise. (ipa_vr_hash_table): Likewise. (ipa_print_node_jump_functions_for_edge): Adjust for bits and m_vr being pointers and vr_known being removed. (ipa_set_jf_unknown): Likewise. (ipa_get_ipa_bits_for_value): New function. (ipa_set_jfunc_bits): Likewise. (ipa_get_value_range): New overloaded functions. (ipa_set_jfunc_vr): Likewise. (ipa_compute_jump_functions_for_edge): Use the above functions to construct bits and vr parts of jump functions. (ipa_check_create_edge_args): Move here from ipa-prop.h, also allocate ipa_bits_hash_table and ipa_vr_hash_table if they do not already exist. (ipcp_grow_transformations_if_necessary): Also allocate ipa_bits_hash_table and ipa_vr_hash_table if they do not already exist. (ipa_node_params_t::duplicate): Do not copy bits, just pointers to them. Fix too long lines. (ipa_write_jump_function): Adjust for bits and m_vr being pointers and vr_known being removed. (ipa_read_jump_function): Use new setter functions to construct bits and vr parts of jump functions or set them to NULL. (write_ipcp_transformation_info): Adjust for bits being pointers. (read_ipcp_transformation_info): Likewise. (ipcp_update_bits): Likewise. Fix excessively long lines a trailing space. Include gt-ipa-prop.h. * ipa-cp.c (propagate_bits_across_jump_function): Adjust for bits being pointers. (ipcp_store_bits_results): Likewise. (propagate_vr_across_jump_function): Adjust for m_vr being a pointer. Do not write to existing jump functions but use a temporary instead.
