Storing a vector constant creates a global constant at the backend:

$ cat foo.ll
define void @foo(<4 x float>* %0) {
  store <4 x float> <float 0., float 1., float 2., float 3.>, <4 x float>* %0, align 4
  ret void
}

$ llc <foo.ll
        .text
        .file   "<stdin>"
        .section        .rodata.cst16,"aM",@progbits,16
        .p2align        4                               # -- Begin function foo
.LCPI0_0:
        .long   0x00000000                      # float 0
        .long   0x3f800000                      # float 1

        .p2align        4, 0x90

        movups  %xmm0, (%rdi)
        retq

Splitting vector store into a bunch of independent stores seems to work:

$ cat bar.ll
define void @bar(<4 x float>* %0) {
  %2 = bitcast <4 x float>* %0 to float*
  %3 = getelementptr inbounds float, float* %2, i64 0
  store float 0., float* %3
  %4 = getelementptr inbounds float, float* %2, i64 1
  store float 1., float* %4
  %5 = getelementptr inbounds float, float* %2, i64 2
  store float 2., float* %5
  %6 = getelementptr inbounds float, float* %2, i64 3
  store float 3., float* %6
  ret void
}

$ llc <bar.ll
        .text
        .file   "<stdin>"
        .globl  bar                             # -- Begin function bar
        .p2align        4, 0x90
        .type   bar,@function
bar:                                    # @bar
        .cfi_startproc

Splitting vector store into a bunch of independent stores seems to work:

It does work for floats, but doesn't work for ints. Looking for another solution.
