Ah scratch that. I compiled your original code (after fixing the compile errors -- there is no such type as "bool" in C). The problem is that (upper << 32) | lower thing. "upper" is a 32-bit type, so shifting it by 32 or more bits is undefined. GCC compiles this to (shortened): 0: mftbu 9 ; mftbl 11 ; mftbu 0 ; cmpw 0,9 ; bne 0b # so far so good slwi 0,0,0 ; or 4,0,11 ; li 3,0 ; blr so it shifts by 0, i.e. it does upper | lower . Case closed, no hardware problem :-) Segher _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
