I think I need to remove it altogether, it fails on x86 as well for float and double, if it also fails on powerpc for long double, then let's get rid of it. Can you confirm that the test pass if you apply the patch below? That will make sure there is no failure further down the test. diff --git a/gcc/testsuite/gfortran.dg/ieee/fma_1.f90 b/gcc/testsuite/gfortran.dg/ieee/fma_1.f90 index 34636426c98..320c73a0c3c 100644 --- a/gcc/testsuite/gfortran.dg/ieee/fma_1.f90 +++ b/gcc/testsuite/gfortran.dg/ieee/fma_1.f90 @@ -38,7 +38,6 @@ print *, sx1 * sx2 + sx3 print *, ieee_fma(sx1, sx2, sx3) if (ieee_fma(sx1, sx2, sx3) /= real(3, kind(sx1)) / 2) stop 4 - !if (ieee_fma(sx1, sx2, sx3) == sx1 * sx2 + sx3) stop 5 !
