# The following should hold here:
#
# 1) The first and second operands of G_INSERT_VECTOR_ELT should be FPRs since
#    they are vectors.
#
# 2) The third operand should be on the register bank given in the test name
#    (e.g, v4s32_fpr). AArch64 supports native inserts of GPRs, so we need to
#    preserve that.
#
# 3) The fourth operand should be a GPR, since it's a constant.
