Hi, My program does not use CRC instructions,but I find the compiled binary has much difference between using "-march=armv8-a+crc" and using "-march=armv8-a". Even stranger, when I use "-march=armv8-a+crc", I find my compiled binary can not run. but when I change -O2 to -O0 based on "-march=armv8-a+crc", it can run. I do not know what is the reason.. can you answer it? Thanks.
