I need SSE2 support but didn't want to adjust dg-options with another
{ target } ... so with default ISA this is valid for x86_64 only
AFAIK? It might be ok for i?86-*-* with -m64 thus that is your
{ i?86-*-* x86_64-*-* } && { ! ia32 } then? But x86_64-*-* -m32
is ok ...
I'll try a
/* { dg-options "-O -fdump-tree-cddce1 -msse2" { target { i?86-*-*
x86_64-*-* } } } */
then.
