      The compiler manual entry for __fmaf indicates it is supported.

      The attached test case has these lines ...

      #include <arm_acle.h>

float fxn(float arg1, float arg2, float arg3)
{
    return __fmaf(arg1, arg2, arg3);
}

      Build it ...

      % tiarmclang -c -mcpu=cortex-r5 -mfloat-abi=hard -mfpu=vfpv3-d16 file.c
file.c:5:12: warning: __fmaf is an ACLE intrinsic but is not supported [-Wacle-intrinsics]
    5 |     return __fmaf(arg1, arg2, arg3);
      |            ^
1 warning generated.

      The resulting code does not use the intrinsic, but calls the function __fmaf.
