for arm cortex-a53 aarch64 mode,
with compile command "armclang.exe --target=aarch64-arm-none-eabi -mcpu=cortex-a53 "
sometimes I meet sync exception,and find stur instruction in disassembly code
is there any cpu feature or compiling option needed for stur?
anyway if I modify the C code so that there is only str (no stur) in disassembly code after compiling, no exception will occur.
any advice is admired, thanks.
