Hi,
trying to compile an atomic command "st64bv" .
while compiling (for ARM core V8.A ) i get an error :
Error: unknown mnemonic `st64bv' -- `st64bv w2,w1,[x0]'using - aarch64-thunderx-elf version 7.3.0thanks
st64bv is an Armv8.7-A extension, you need a compiler and assembler that supports it. GCC 7.3.0 is too old.
