------- Comment #11 from irar at il dot ibm dot com 2007-10-10 13:23 ------- I understand that those symbols have to be renamed, I am just saying that maybe it should be done in the gimplifier and not in the vectorizer. But since force_gimple_operand_bsi also goes through the statements list, I guess it is reasonable to do the same thing in the vectorizer. Or we can add a new API like force_gimple_operand_and_mark_for_renaming.
Anyway, I tried your patch. Now we get a different ICE: internal compiler error: in referenced_var_lookup, at tree-dfa.c:642 D.1556 is marked for renaming but then during update_ssa it cannot find it - htab_find_with_hash (tree-dfa.c:641) returns NULL. #0 referenced_var_lookup (uid=1556) at ../../gcc/gcc/tree-dfa.c:642 #1 0x00000000006f9308 in update_ssa (update_flags=2048) at ../../gcc/gcc/tree-into-ssa.c:3207 #2 0x0000000000aac184 in vect_transform_loop (loop_vinfo=0xe94410) at ../../gcc/gcc/tree-vect-transform.c:7431 #3 0x00000000007fae09 in vectorize_loops () at ../../gcc/gcc/tree-vectorizer.c:2507 #4 0x0000000000631726 in execute_one_pass (pass=0xdfc0c0) at ../../gcc/gcc/passes.c:1116 #5 0x00000000006318ec in execute_pass_list (pass=0xdfc0c0) at ../../gcc/gcc/passes.c:1169 #6 0x00000000006318fe in execute_pass_list (pass=0xdfbee0) at ../../gcc/gcc/passes.c:1170 #7 0x00000000006318fe in execute_pass_list (pass=0xdfb2e0) at ../../gcc/gcc/passes.c:1170 #8 0x00000000007086ce in tree_rest_of_compilation (fndecl=0x2ba807b05800) at ../../gcc/gcc/tree-optimize.c:404 #9 0x000000000088a054 in cgraph_expand_function (node=0x2ba807b05900) at ../../gcc/gcc/cgraphunit.c:1070 #10 0x000000000088bbe7 in cgraph_optimize () at ../../gcc/gcc/cgraphunit.c:1139 #11 0x00000000004144fe in c_write_global_declarations () at ../../gcc/gcc/c-decl.c:8077 #12 0x00000000006ad2e7 in toplev_main (argc=<value optimized out>, argv=<value optimized out>) at ../../gcc/gcc/toplev.c:1052 #13 0x00002ba8077d5154 in __libc_start_main () from /lib64/libc.so.6 #14 0x0000000000403cf9 in _start () Thanks, Ira -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33680
