2017-03-01 Martin Jambor <mjambor@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. From-SVN: r245805
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
