From: "uros at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug rtl-optimization/64557] get_addr in true_dependence_1 cannot handle VALUE inside an expr Date: Fri, 20 Feb 2015 12:05:00 -0000 [thread overview] Message-ID: <bug-64557-4-qzAjy6lHdx@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-64557-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64557 --- Comment #5 from uros at gcc dot gnu.org --- Author: uros Date: Fri Feb 20 12:04:21 2015 New Revision: 220854 URL: https://gcc.gnu.org/viewcvs?rev=220854&root=gcc&view=rev Log: Backport from mainline 2015-01-22 Wei Mi <wmi@google.com> PR rtl-optimization/64557 * dse.c (record_store): Call get_addr for mem_addr. (check_mem_read_rtx): Likewise. Backport from mainline 2014-10-20 Uros Bizjak <ubizjak@gmail.com> * varasm.c (const_alias_set): Remove. (init_varasm_once): Remove initialization of const_alias_set. (build_constant_desc): Do not set alias set to const_alias_set. Backport from mainline 2014-10-14 Uros Bizjak <ubizjak@gmail.com> PR rtl-optimization/63475 * alias.c (true_dependence_1): Always use get_addr to extract true address operands from x_addr and mem_addr. Use extracted address operands to check for references with alignment ANDs. Use extracted address operands with find_base_term and base_alias_check. For noncanonicalized operands call canon_rtx with extracted address operand. (write_dependence_1): Ditto. (may_alias_p): Ditto. Remove unused calls to canon_rtx. Backport from mainline 2014-10-10 Uros Bizjak <ubizjak@gmail.com> PR rtl-optimization/63483 * alias.c (true_dependence_1): Do not exit early for MEM_READONLY_P references when alignment ANDs are involved. (write_dependence_p): Ditto. (may_alias_p): Ditto. Backport from mainline 2013-03-26 Richard Biener <rguenther@suse.de> * alias.c (find_base_term): Avoid redundant and not used recursion. (base_alias_check): Get the initial base term from the caller. (true_dependence_1): Compute and pass base terms to base_alias_check. (write_dependence_p): Likewise. (may_alias_p): Likewise.
