I believe it's present in every version that supports the aarch64 target. I have been using GCC configured with: configure --host=i686-pc-linux-gnu --build=i686-pc-linux-gnu --target=aarch64-unknown-linux-gnu --enable-languages=c,c++ --enable-threads=posix --enable-shared --disable-libsanitizer --disable-gnu-indirect-function --disable-gnu-unique-object --with-sysroot=/gcc-debug/Linux-aarch64-sysroot --disable-multilib The simplest reproduction case that I've found is to precompile a header with exactle one line in it, call it precomp.h: #define CEILF(f) ceilf(f) Compile the PCH with: aarch64-unknown-linux-gnu-gcc -nostdinc -march=armv8-a -fPIC -O2 -ftree-vectorize -x c++-header -c precomp.h -o precomp.h.ghc Then build the attached longish creduce'd test case with: aarch64-unknown-linux-gnu-gcc -nostdinc -march=armv8-a -fPIC -O2 -ftree-vectorize -x c++ -include precomp.h -Winvalid-pch -c test.c It fails with SEGV: test.c: In function ‘void x127()’: test.c:141:1: internal compiler error: Segmentation fault x127 () ^ 0x899d958 crash_signal /gcc-debug/gcc-svn/gcc/toplev.c:337 0x81bbd62 contains_struct_check(tree_node*, tree_node_structure_enum, char const*, int, char const*) /gcc-debug/gcc-svn/gcc/tree.h:2841 0x87208ca gimple_build_call_1 /gcc-debug/gcc-svn/gcc/gimple.c:216 0x872093d gimple_build_call_vec(tree_node*, vec<tree_node*, va_heap, vl_ptr>) /gcc-debug/gcc-svn/gcc/gimple.c:230 0x8bd85e0 vectorizable_call /gcc-debug/gcc-svn/gcc/tree-vect-stmts.c:2470 0x8be7b1f vect_transform_stmt(gimple_statement_base*, gimple_stmt_iterator*, bool*, _slp_tree*, _slp_instance*) /gcc-debug/gcc-svn/gcc/tree-vect-stmts.c:7237 0x8bfb143 vect_transform_loop(_loop_vec_info*) /gcc-debug/gcc-svn/gcc/tree-vect-loop.c:6079 0x8c0e4f1 vectorize_loops() /gcc-debug/gcc-svn/gcc/tree-vectorizer.c:478 0x8b1c75c execute /gcc-debug/gcc-svn/gcc/tree-ssa-loop.c:232 It looks like the reason for the failure is that the global table aarch64_builtin_decls in aarch64-builtins.c isn't relocated when loading the PCH. All of the nodes that it points to are freed, and the memory may get reused (or poisoned, if that's enabled). The table is properly annotated with the GTY macro, but aarch64-builtins.c isn't in GTFILES so it's not processed by the type generator. If I manually add aarch64-builtins.c to target_gtfiles (and include the resulting gt-aarch64-builtins.h at the bottom of the C file) then this problem goes away. >From gcc-bugs-return-457616-listarch-gcc-bugs=gcc.gnu.org@gcc.gnu.org Sat Aug 02 15:23:57 2014 Return-Path: <gcc-bugs-return-457616-listarch-gcc-bugs=gcc.gnu.org@gcc.gnu.org> Delivered-To: listarch-gcc-bugs@gcc.gnu.org Received: (qmail 4187 invoked by alias); 2 Aug 2014 15:23:56 -0000 Mailing-List: contact gcc-bugs-help@gcc.gnu.org; run by ezmlm Precedence: bulk List-Id: <gcc-bugs.gcc.gnu.org> List-Archive: <http://gcc.gnu.org/ml/gcc-bugs/> List-Post: <mailto:gcc-bugs@gcc.gnu.org> List-Help: <mailto:gcc-bugs-help@gcc.gnu.org> Sender: gcc-bugs-owner@gcc.gnu.org Delivered-To: mailing list gcc-bugs@gcc.gnu.org Received: (qmail 4121 invoked by uid 48); 2 Aug 2014 15:23:53 -0000 From: "olegendo at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug other/29842] [meta-bug] outstanding patches / issues from STMicroelectronics Date: Sat, 02 Aug 2014 15:23:00 -0000 X-Bugzilla-Reason: CC X-Bugzilla-Type: changed X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: gcc X-Bugzilla-Component: other X-Bugzilla-Version: 4.2.0 X-Bugzilla-Keywords: meta-bug X-Bugzilla-Severity: normal X-Bugzilla-Who: olegendo at gcc dot gnu.org X-Bugzilla-Status: NEW X-Bugzilla-Priority: P3 X-Bugzilla-Assigned-To: unassigned at gcc dot gnu.org X-Bugzilla-Target-Milestone: --- X-Bugzilla-Flags: X-Bugzilla-Changed-Fields: Message-ID: <bug-29842-4-K4KxaQ9TVv@http.gcc.gnu.org/bugzilla/> In-Reply-To: <bug-29842-4@http.gcc.gnu.org/bugzilla/> References: <bug-29842-4@http.gcc.gnu.org/bugzilla/> Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: 7bit X-Bugzilla-URL: http://gcc.gnu.org/bugzilla/ Auto-Submitted: auto-generated MIME-Version: 1.0 X-SW-Source: 2014-08/txt/msg00113.txt.bz2 Content-length: 539 https://gcc.gnu.org/bugzilla/show_bug.cgi?id)842 --- Comment #4 from Oleg Endo <olegendo at gcc dot gnu.org> --- (In reply to Oleg Endo from comment #3) > (In reply to Jorn Wolfgang Rennecke from comment #2) > > For the -mrelax breakage, also see: > > http://sourceware.org/bugzilla/show_bug.cgi?id298 > > Fixes for -mrelax have been posted by Renesas in 2009: > > https://sourceware.org/bugzilla/show_bug.cgi?id\x10373 > https://sourceware.org/bugzilla/show_bug.cgi?id\x10378 These two issues have been now been fixed in binutils. ^ permalink raw reply [flat|nested] 8+ messages in thread

That is the correct fix. I am testing this fix then and will be applying to the trunk as obvious after I test it. ^ permalink raw reply [flat|nested] 8+ messages in thread
