AM6442: tiarmclang: suppress warnings from inside code

Tool/software:

Hi,

we are currently working on a project with MCU+ SDK for AM64 and using tiarmclang as compiler. However, when compiling, hundreds of warnings are being generated, and most of them come from inside the SDK header files, which are included many times over different ways:

We would like to turn off the warnings at places, where those files get included and to keep the warning for the rest of the code. In GCC that would be done with the help of the corresponding pragmas:

#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wuninitialized"
  foo(b);                       /* no diagnostic for this one */
#pragma GCC diagnostic pop

Unfortunately, until now we didn't find a way to do this with tiarmclang. Is this feature implemented at all?

Regards!
