I remember some people not wanting to touch gold with a 10-foot pole, but that might just have been my impression. I agree that adding BE8 to gold would be easier, but there's a difference between "works on my box" and "Linaro has validated it". I wouldn't want to claim the latter if we only do the former. > Not that it is of much use to you, but ARM's proprietary toolchain > supports LTO for bare-metal via clang, including v7a, and we (ARM) > haven't seen any problems with code-generation due to LTO in the tests > that we run. Big endian, too? _______________________________________________ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org https://lists.linaro.org/mailman/listinfo/linaro-toolchain
