Hi,
allyesconfig and multi_v7_defconfig fail to build on recent linux-next
on GCC 6.2.0.
Errors:
../arch/arm/crypto/aes-cipher-core.S: Assembler messages:
../arch/arm/crypto/aes-cipher-core.S:21: Error: selected processor does not support `tt .req ip' in ARM mode
../arch/arm/crypto/aes-cipher-core.S:174: Error: ARM register expected -- `movw tt,#:lower16:crypto_ft_tab'
../arch/arm/crypto/aes-cipher-core.S:174: Error: ARM register expected -- `movt tt,#:upper16:crypto_ft_tab'
Compiler: arm-linux-gnueabi-gcc (Ubuntu 6.2.0-5ubuntu12) 6.2.0 20161005
Git bisect pointed to:
first bad commit: [81edb42629758bacdf813dd5e4542ae26e3ad73a] crypto: arm/aes - replace scalar AES cipher
Best regards,
Krzysztof

It's worth pointing out that _assembler_ messages come from _binutils_
rather than _gcc_. Please advise which version of _binutils_ you
are using. Thanks.

Ah, yes, so the binutils 2.27 (Ubuntu package: 2.27-8ubuntu2).
However Ard mentioned that this is already fixed.
Best regards,
