--- Comment #5 from Dominique d'Humieres <dominiq at lps dot ens.fr> 2011-03-28 18:26:52 UTC ---
The patch in comment #3 fixes the ICE, but the test still fails:
FAIL: gcc.dg/vect/pr38529.c scan-tree-dump-times vect "OUTER LOOP VECTORIZED" 1
Compiling with -Ofast -ftree-vectorizer-verbose=2 I get
/opt/gcc/_clean/gcc/testsuite/gcc.dg/vect/pr38529.c:11: note: not vectorized:
unsupported data-type
/opt/gcc/_clean/gcc/testsuite/gcc.dg/vect/pr38529.c:6: note: vectorized 0 loops
in function.
With revision 171398 I get
/opt/gcc/_clean/gcc/testsuite/gcc.dg/vect/pr38529.c:10: note: LOOP VECTORIZED.
/opt/gcc/_clean/gcc/testsuite/gcc.dg/vect/pr38529.c:10: note: OUTER LOOP
VECTORIZED.
/opt/gcc/_clean/gcc/testsuite/gcc.dg/vect/pr38529.c:6: note: vectorized 1 loops
in function.
No other test fails in gcc/testsuite/*/vect/* (full test for tonight).
