Target: x86_64-unknown-linux-gnu, *-*-solaris2*
Build: x86_64-unknown-linux-gnu, *-*-solaris2*
The new gfortran.dg/round_4.f90 test FAILs to execute on both Solaris/x86 and
SPARC
and Linux/x86_64:
FAIL: gfortran.dg/round_4.f90 -O0 execution test
FAIL: gfortran.dg/round_4.f90 -O1 execution test

The test aborts with a useless backtrace:

--- Comment #3 from Tobias Burnus <burnus at gcc dot gnu.org> ---
Quoting round_4.f90, which somehow no one seems to read ...
! Test whether I/O rounding works. Uses internally (libgfortran) strtod
! for the conversion - and sets the CPU rounding mode accordingly.
!
! If it doesn't work on your system, please check whether strtod handles
! rounding and whether your system is supported in libgfortran/config/fpu*.c
!
! Please only add ... run { target { ! { triplets } } } if it is unfixable
! on your target - and a note why (strtod doesn't handle it, no rounding
! support, etc.)
Thus, one way forward would be to exclude the target (Solaris, FreeBSD) - or to
simply add XFAIL as it also only works with very recent GLIBCs.
Alternatively, one could also think about a different technique for handling
the rounding (on input) in libgfortran.

Created attachment 30692
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=30692&action=edit
determine rounding support at runtime
How about this?
With this patch the test case should pass most of the time.
