| Description |

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]

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. |
