Thanks for the fix, now for the attached test, main loop will not have any
load.
There is a remaining issue that the loop epilogue still contains load from
stack and constant pool
.L9:
movslq %edx, %rax
movss 72(%rsp), %xmm5
salq $2, %rax
leaq (%rbx,%rax), %rcx
movaps %xmm5, %xmm1
subss (%rcx), %xmm1
andps .LC4(%rip), %xmm1
movss %xmm1, (%rcx)
leal 1(%rdx), %ecx
addss %xmm1, %xmm0
cmpl %ecx, %r12d
jle .L8
IRA dump shows the pseudos does not have conflict but they still failed to be
allocated with register. This issue does not exist on aarch64.
