Hi,
This patch series is a work in progress towards getting the compiler to
generate better code for constructors and dups in both NEON and SVE
targets. It first changes the backend to use rtx_vector_builder for
vector_init's. Then it is followed by some prepraration passes to better
handle VLA VEC_PERM_EXPRs followed by the addition of a new TARGET_HOOK
VLA_CONSTRUCTOR that is used to expand VLA VEC_PERM_EXPRs, all based on
Prathamesh's initial work in this area. As I said before, this is still
work in progress, though I suspect the first two patches could go in but
I was trying to get the series ready to post to make sure the first
patches were in the right shape.
I have put this work on hold right now, but I heard Prathamesh might
want to pick this up, feel free to use any of this, or discard as you
see fit.
