[botan-devel] Disable Thumb mode for ARM?

Hi Everyone,

I'm having trouble with botan-test on a Raspberry Pi 3 with the ARMv8
instruction set. I'd like to try disabling thumb mode. (Related, see
"ARMv8/Aarch32 and error: unable to emulate ‘TI’",
http://github.com/randombit/botan/issues/563).

Configure does not look like it provides a preconfigured switch:

    $ ./configure.py --help | egrep -i '(arm|thumb)'
    $

How do I configure Botan to not use thumb mode on ARM platforms?

Thanks in advance.
