Indeed I did not!-(I have never succeeded with the regenerate process: not = the right version, =E2=80=A6). > The patch was sent without this regenerated file, as is (as I understand)= the custom on gcc-patches. >=20 > Attached is the full diff, including Makefile.in. With the updated patch the test gfortran.dg/ieee/large_1.f90 compiles, but = fails at run time due to the lines if (.not. ieee_support_underflow_control(x1)) call abort and if (.not. ieee_support_underflow_control(x2)) call abort IIRC Uros said that underflow id not supported for __float128.
