Author: aoliva Date: Mon Apr 30 18:41:11 2007 New Revision: 124302 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=124302 Log: PR middle-end/22156 Temporarily revert: 2007-04-06 Andreas Tobler <[EMAIL PROTECTED]> 2007-04-05 Alexandre Oliva <[EMAIL PROTECTED]> * tree-sra.c (try_instantiate_multiple_fields): Needlessly initialize align to silence bogus warning. 2007-04-05 Alexandre Oliva <[EMAIL PROTECTED]> * tree-sra.c (struct sra_elt): Add in_bitfld_block. Remove all_no_warning. (struct sra_walk_fns): Remove use_all parameter from use. (sra_hash_tree): Handle BIT_FIELD_REFs. (sra_elt_hash): Don't hash bitfld blocks. (sra_elt_eq): Skip them in parent compares as well. Handle BIT_FIELD_REFs. (sra_walk_expr): Don't maintain or pass down use_all_p. (scan_use): Remove use_all parameter. (scalarize_use): Likewise. Re-expand assignment to BIT_FIELD_REF of gimple_reg. De-scalarize before input or output, and re-scalarize after output. Don't mark anything for no warning. (scalarize_ldst): Adjust. (scalarize_walk_gimple_modify_statement): Likewise. (build_element_name_1): Handle BIT_FIELD_REFs. (instantiate_element): Don't warn for any element whose parent is used as a whole. (instantiate_missing_elements_1): Return the sra_elt. (canon_type_for_field): New. (try_instantiate_multiple_fields): New. (instantiate_missing_elemnts): Use them. (mark_no_warning): Removed. (generate_one_element_ref): Handle BIT_FIELD_REFs. (REPLDUP, sra_build_elt_assignment): New. (generate_copy_inout): Use them. (generate_element_copy): Likewise. Handle bitfld differences. (generate_element_zero): Don't recurse for blocks. Use sra_build_elt_assignment. (generate_one_element_int): Take elt instead of var. Use sra_build_elt_assignment. (generate_element_init_1): Adjust. (scalarize_use, scalarize_copy): Use REPLDUP. (scalarize_ldst): Move assert before dereference. (dump_sra_elt_name): Handle BIT_FIELD_REFs.
