  Hi all,

This patch series enables unrolling of an unpredicated main vectorized 
loop based on a target hook. The epilogue loop will have (at least) half 
the VF of the main loop and can be predicated.

Andre Vieira (3):
[vect] Add main vectorized loop unrolling
[vect] Consider outside costs earlier for epilogue loops
[AArch64] Implement vect_unroll backend hook
