------- Comment #14 from irar at il dot ibm dot com  2008-09-22 09:24 -------
This patch causes the following failures on ppc:

FAIL: gcc.dg/vect/pr35821-altivec.c scan-tree-dump-times vect "vectorized 1
loops" 1

FAIL: gcc.dg/vect/slp-perm-7.c scan-tree-dump-times vect "vectorizing stmts

For example, for slp-perm-1.c:

slp-perm-1.c:23: note: ==> examining statement: a_7 = *pInput_40;
slp-perm-1.c:23: note: get vectype with 4 units of type unsigned int
slp-perm-1.c:23: note: vectype: __vector unsigned int
...
slp-perm-1.c:23: note: ???  vector type does not alias scalar type
...
slp-perm-1.c:23: note: not vectorized: relevant stmt not supported: a_7 =
*pInput_40;

pInput_40 is unsigned int*
(a_7 is unsigned int)
