           Summary: libgfortran on sysv never uses fpsetmask
           Product: gcc
           Version: 4.5.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libfortran
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: nicolai.stange@zmaw.de


I'm working on Solaris10/SPARC.

nic@nic-desktop:~/gcc-4.5.3$ grep -r have_fpsetmask . | grep -v libgfor_
./libgfortran/configure.host:if test "x${have_fpsetmask}" = "xyes"; then
nic@nic-desktop:~/gcc-4.5.3$

have_fpsetmask won't ever be set anywhere.
libgfor_cv_have_fpsetmask ist set and should be tested instead.

This results in set_fpu coming from fpu-generic.h.
Compiling code w. -ffpe-trap=invalid,zero,overflow results in the following
warnings when executing the code:
Fortran runtime warning: IEEE 'invalid operation' exception not supported.
Fortran runtime warning: IEEE 'division by zero' exception not supported.
Fortran runtime warning: IEEE 'overflow' exception not supported.

Best regards

Nicolai
