I was just looking over the nested fault handler this thread came to mind. There is exactly that situation with '.pred.rel "mutex", p6, p7' where gas should be able to infer this from the 'cmp.eq p6,p7 = 5,r17' preceding this and there are no intermediate labels. Perhaps there is a reason why gas works this way that I'm missing? --cw
