The linux system has arm64 having arm architecture armv8-a. How to know whether debian is running hard float or soft float?
回答1:
In compliance with AAPCS64, GNU GCC for armv8 only provides the hard float aarch64 toolchain. This is unlike GCC for armv7-a, which provides arm-linux-gnueabi soft float toolchain and arm-linux-gnueabihf hard float toolchain.
