Cryptogams AES and SHA on ARM

[Jeffrey Walton]

Hi Everyone,

We noticed Cryptogams SHA for ARM was not performing well under Clang. After some investigation we found an issue in our defines, like CRYPTOPP_ARM_NEON_AVAILABLE. We also found an issue in our CPU_ProbeARMv7() code under Clang.

The issues have been cleared, and SHA is performing as expected with Clang.

We also enabled Cryptogams AES for ARM under Clang. Previously this was disabled. We think we cleared the problems related to two crashes, so AES is now enabled.

I still have one issue to clear for Microsoft Aarch64 platforms.

Please ping us if you see anything unusual.

Jeff
