The solution Arm's proprietary toolchain had to this problem is for the linker to select libraries based on build-attibutes. It would detect the rounding mode build attribute and select the appropriate library variant, but that isn't available to us here. A colleague suggested an easily available customisation point that someone that had a local need for a different rounding mode could implement.
I'm happy with Yi's latest update. Do we have anyone left with any objections? If there aren't any I'm inclined to approve.
