tiarmclang silently ignores #pragma FUNCTION_OPTIONS, when a diagnostic is expected

XMLWordPrintable

    • Type: Bug
    • Resolution: Fixed
    • Priority: Medium

      This code ...

      #pragma FUNCTION_OPTIONS(fxn, "--opt_level=3")
#pragma FUNC_EXT_CALLED(fxn)
int fxn(int arg)
{
    return arg + 3;
}

      ... compiles clean with TI Arm compiler armcl. And even though only --opt_level=0 is used, it is optimized at level 3. Try the same thing with tiarmclang ...

      % tiarmclang -c file.c
file.c:2:9: warning: pragma FUNC_EXT_CALLED is a legacy TI pragma and not supported in clang
      compilers. [-Wti-pragmas]
    2 | #pragma FUNC_EXT_CALLED(fxn)
      |         ^
1 warning generated.

      A diagnostic is emitted for FUNC_EXT_CALLED. A diagnostic is expected for FUNCTION_OPTIONS, but it does not appear. Furthermore, the generated code is not optimized.
