This patch addresses the failures caused by the
gcc.c-torture/execute/20101011-1.c test on aarch64. The reason why this
test fails is because aarch64 does not trap on integer division by zero.

Is this OK for trunk? If so, please commit it because I do not have an
svn account.


ENOPATCH


Sorry about that. I attached the patch this time.

Is there any reference you can point at which states that division byzero does not trap? There's clearly some confusion here since the oldcode claimed that the trap occurs, but that it might not raise a SIGFPEon some systems.


Or if one of the aarch64 maintainers could chime in, that'd be helpful too.
