In AC5, we use --diag_suppress to suppress warnings. I learn in Arm Compiler armclang Reference Guide Version 6.12 that -Wno can do the same thing. But how shoulo I use -Wno to suppress multiple warnings?
In AC5, --diag_suppress=188,111,186,1 could work. I tried to use -Wno=188,111,186,1 and went wrong.
The warnings (and errors) format that armclang generates are very different to armcc. You can disable groups of warnings, with (for example) -Wno-parentheses, for warnings related to how parentheses "()" are used in your code.
-Wno-all, would disable all warnings.
