Today's build of xstormy16-elf failed due to a branch to an out of range target. Manual inspection of the assembly code for the affected function (divdi3) showed that the zero-extension patterns were claiming a length of 2, but clearly assembled into 4 bytes. This patch adds an explicit length to the zero extension pattern and appears to resolve the issue in my test builds.
