Using cmake to build inline assembly code got an error: no such instruction: `isb 0xF'

Hello all,

I am trying to compile STM32G4xx_HAL_Driver using gcc toolchain in Alpine. I am using the cmakelist template from cmake community, below is the link:

The compiling failed at: libraries/CMSIS/Include/cmsis_gcc.h:935: Error: no such instruction: `isb 0xF'.

The code is inline assambly:

__STATIC_FORCEINLINE void __ISB(void)

{

__ASM volatile ("isb 0xF":::"memory");

}

I can't find any good answers from Internet, so post a help message here.

Can anyone help me out of this issue?

Thanks.

After I installed newlib in Alpine docker, the problem has gone.
