Hello all, Recently i noticed that register allocation for the operands in a unspec pattern was going wrong. This was because there was no conflict between the registers used in the unspec pattern and the other registers which should have been there. During debugging i found out that the code is written in such a way that it doesn't consider registers used inside an unspec expression. So i rewrote the patten so that the unspec is in the source rather than in the destination of the pattern. That solved the issue. But is this expected? Will the allocation also go wrong for the source operands if they contain registers inside an unpsec expression? I still haven't encountered this.
What about live analysis. How are the registers inside an unspec expression handled there? Regards, Shafi
