Hi Rainer,
It turns out that the FMA3 and FMA4 tests in acinclude.m4 don't test
what they claim to: if one compiles the test program
float
flt_mul_add (float a, float b, float c)
{
return __builtin_fmaf (a, b, c);
}
with -O2 -mfma -mno-fma4 (FMA3) resp. -O2 -mfma4 -mno-fma (FMA4), bot
ective_target_fma in gcc.target/i386/i386.exp.
(LIBGFOR_CHECK_FMA4): Use test from check_effective_target_fma4.
* configure: Regenerate.
