I assume this question is somewhat independent of the PR. I didn't think that this was necessary. There is some somewhat horrible code to save register r1 into the frame and restore it in the delay slot of a jump in situations where we need a register for the jump (i.e., the jump is too large to be handled using a pc-relative offset). The downside is the jump needs several instructions more than would be needed if we had a register handy. Dave -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24626
