I don't see that being used in any part of llvm-arm.cpp, for example,

bool llvm_arm_should_pass_or_return_aggregate_in_regs(tree TreeType,
                                                      CallingConv::ID &CC) {
  // Homogeneous aggregates are an AAPCS-VFP feature.
  if ((CC != CallingConv::ARM_AAPCS_VFP) ||
      !(TARGET_AAPCS_BASED && TARGET_VFP && TARGET_HARD_FLOAT_ABI))
    return false;

So checking  TARGET_HARD_FLOAT_ABI is probably consistent with what
the rest of the file does right now.

I don't see gcc/testsuite/gcc.target/arm/aapcs in llvm-gcc, only in
vanilla gcc...
