There are i?86 targets which can use -m64 (i386-pc-solaris2.10) and x86_64
targets which can use -m32 (most or all of them).  In both cases,
--disable-multilib can be used so that only -m32, or only -m64 is available. 
Tests requiring 32-bit x86 can run on both i?86 and x86_64, as can tests
requiring 64-bit, in both cases provided the right multilib is enabled.

At present, many tests are enabled only for i?86, or only for x86_64; instead
they should be enabled for both, restricted to ilp32 or lp64 as appropriate.  In
addition, it is inappropriate for tests to hardcode -m32 on x86_64 as
i386-pentium4-not-mull.c, setjmp-2.c, short-compare-1.c, short-compare-2.c in
gcc.dg do, because --disable-multilib can be used and those tests presently fail
with --disable-multilib; instead, special options should be specified as
appropriate for 32-bit x86 and it should be up to the testsuite user to run it
with both -m32 and -m64 if they wish to do so.

As noted at <http://gcc.gnu.org/ml/gcc-patches/2005-04/msg00199.html>, x86,
x86_ilp32 and x86_lp64 effective-target keywords would simplify fixing these
issues, although there are still tests e.g. restricted to x86(_64)-linux-gnu as
well as those which care about the CPU and not the OS.
