What is the correct statement to put ARM instruction DMB (Data Memory Barrier) with an option of “ST”?
Based on: infocenter.arm.com/help/index.js … GHHIE.html
Without the option, this statement works:
asm(" DMB");
I try with:
asm(" DMB ST");
I am getting an error:
{standard input}: Assembler messages:
{standard input}:557: Error: garbage following instruction – `dmb ST’

Thanks.
