The remaining problem is the support for ncopies > 1 in
vectorizable_condition. http://gcc.gnu.org/ml/gcc-patches/2010-09/msg00550.html
implements this.

Cleanup comparisons of types
This patch replaces with types_compatible_p all the places in the
vectorizer that wer

This cleanup of vectorizable_condition allows this testcase to be vectorized:
typedef int uint8_t;
vsad16_c (void *c, uint8_t * s1, uint8_t * s2, int stride, int h)
{
int score = 0;
int x, y;
for (x = 0; x < 16;

vectorizable_condition has to be cleaned up of this condition:
/* We do not handle two different vector types for the condition
and the values. */
if (TREE_TYPE (TREE_OPERAND (cond_expr, 0)) != TREE_TYPE (vec

Reduced testcase, for which ncopies is 4.
typedef unsigned char uint8_t;
vsad16_c (void *c, uint8_t * s1, uint8_t * s2, int stride, int h)
{
int score = 0;
int x, y;
for (x = 0; x < 16; x++)
score += ((s1[x]

Due to the "FORNOW" fail in vectorizable_condition:
int nunits = TYPE_VECTOR_SUBPARTS (vectype);
int ncopies = LOOP_VINFO_VECT_FACTOR (loop_vinfo) / nunits;
if (ncopies > 1)
return false; /* FORNOW */
