Hi Everyone,
I have an Aarch64 dev board. I want to build out a test case for both
CRC and Crypto extensions in an Aarch32 execution environment. Its not
clear to me how to do it.
I know I can activate CRC with (Crypto is similar):
gcc -march=armv8-a+crypto ...
My question is, what do I add for the 32-bit binary? Is it as simple
as -m32, or do I need to do something else?
Thanks in advance.
Jeff
