From: "clyon at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug target/64829] New: [ARM] ICE at -O3 in vect_get_vec_def_for_stmt_copy Date: Wed, 28 Jan 2015 09:54:00 -0000 [thread overview] Message-ID: <bug-64829-4@http.gcc.gnu.org/bugzilla/> (raw) https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64829 Bug ID: 64829 Summary: [ARM] ICE at -O3 in vect_get_vec_def_for_stmt_copy Product: gcc Version: unknown Status: UNCONFIRMED Severity: normal Priority: P3 Component: target Assignee: unassigned at gcc dot gnu.org Reporter: clyon at gcc dot gnu.org Compiling the attached testcase at -O3 results in an ICE. GCC is configured as: --target=arm-none-linux-gnueabihf --with-mode=arm --with-cpu=cortex-a9 --with-fpu=neon Compiling at -O2 -Wall warns that several local variables are unintialized. Initializing val1=0 makes the ICE disappear. arm-none-linux-gnueabihf-gcc -Wall gcc_vect_bug.c -c -O3 gcc_vect_bug.c: In function 'fail': gcc_vect_bug.c:22:5: internal compiler error: in vect_get_vec_def_for_stmt_copy, at tree-vect-stmts.c:1598 int fail ( const RMColorData * pInColor, ^ 0xfb2c34 vect_get_vec_def_for_stmt_copy(vect_def_type, tree_node*) /media/lyon/9be1a707-5b7f-46da-9106-e084a5dbb011/ssd/src/GCC/sources/gcc-fsf/trunk/gcc/tree-vect-stmts.c:1598 0xfb2d3d vect_get_vec_defs_for_stmt_copy /media/lyon/9be1a707-5b7f-46da-9106-e084a5dbb011/ssd/src/GCC/sources/gcc-fsf/trunk/gcc/tree-vect-stmts.c:1624 0xfbeac3 vectorizable_operation /media/lyon/9be1a707-5b7f-46da-9106-e084a5dbb011/ssd/src/GCC/sources/gcc-fsf/trunk/gcc/tree-vect-stmts.c:4910 0xfc658d vect_transform_stmt(gimple_statement_base*, gimple_stmt_iterator*, bool*, _slp_tree*, _slp_instance*) /media/lyon/9be1a707-5b7f-46da-9106-e084a5dbb011/ssd/src/GCC/sources/gcc-fsf/trunk/gcc/tree-vect-stmts.c:7273 0xfdbcf3 vect_transform_loop(_loop_vec_info*) /media/lyon/9be1a707-5b7f-46da-9106-e084a5dbb011/ssd/src/GCC/sources/gcc-fsf/trunk/gcc/tree-vect-loop.c:6156 0xff1deb vectorize_loops() /media/lyon/9be1a707-5b7f-46da-9106-e084a5dbb011/ssd/src/GCC/sources/gcc-fsf/trunk/gcc/tree-vectorizer.c:497 0xee638f execute /media/lyon/9be1a707-5b7f-46da-9106-e084a5dbb011/ssd/src/GCC/sources/gcc-fsf/trunk/gcc/tree-ssa-loop.c:295
