Hi,
This patch changes NEON's default vector size from 64 to 128 bits.
The patch doesn't touch mvectorize-with-neon-quad, but removes the
uses of TARGET_NEON_VECTORIZE_QUAD.
Following Julian's suggestion I added a param preferred-vector-size
for testing and debugging purposes.
IIUC, this patch makes mvectorize-with-neon-quad effectively a no-op
which is ok with me.
If this is now the default, what is the behaviour of
-mno-vectorize-with-neon-quad now ? Should that set the value of the
parameter to 64 or should we be rejecting the negative of that option ?
If not, we should then consider adding a RejectNegative to that option.
cheers
