Hi All,

After the fix to the addsub patch yesterday for bootstrap I had only regtested on x86.
While looking today it seemed the new tests were failing, this was caused
by a change in the behavior of the GET_MODE_WIDER_MODE macro on trunk.

This patch fixes that issue. Sorry for the mess, have rebased all branches now.

Bootstrapped Regtested on aarch64-none-linux-gnu and no issues.

Ok for master?

Thanks,
Tamar
