Pattern transformation between scalar and vector on IR.
Hi All,
I'm tring to use RSQRT instructions on follow case for ARM
(now what using is sqrt):
1.0 / sqrt(x)
The RSQRT instructions(VRSQRTE/VRSQRTS) are vector type,
but above operation is scalar type. So a transformation must be
done(transform sqrt pattern to rsqrt).
I have completed a patch for this, but I made the transformation in the
backend which will leads to additional
