George Koehler 2c266c631a Reorder registers. Fix problem with ret 8. ... After c5bb3be, ncg began to allocate regvars from r13 up. I reorder the regvars so ncg again allocates them from r31 down. I also reorder the other registers. This exposed a bug in my rule for ret 8. It was wrong if item %2 was in r3, because I moved %1 to r3 before %2 to r4. Fix it by adding back an individual register class for r3 (called REG3 here, GPR3 in c5bb3be). Also fix my typo in mach.c that made a syntax error in assembly.		2017-02-17 19:32:27 -05:00
