Running armv7 binaries on armv8

Hi Experts,

I have binaries built for armv7 architecture, without rebuilding binaries can I run on armv8?. I think its possible, but wanted confirm is there any limitation?

Thanks,

Veeranna

ARMv8-A contains the AArch32 "profile", but you need to be in the respective mode. So if the CPU is set to execute AArch64 it does not understand 32 bit code (as for ARMv7).
So in case of Linux, I guess the bootloader has to know this already.

Can this be done without running an Armv7 installation or does the whole CPU need to be set into armv7 mode?
