This breaks 32-bit big-endian (as well as making the code longer and more complex).And in fact none of this code will get executed in little-endian mode anyway, since we still have this in the middle of emulate_step(): /* * Following cases are for loads and stores, so bail out * if we're in little-endian mode. */ if (regs->msr & MSR_LE) return 0; Paul.See patch 1/3 to explain how it becomes relevant in LE. I will take another look at the change.
It appears that patch 1/3 never got picked up, even though I thought Ben & I had worked through that. And I agree that the code could be simpler. I will work up a patch to address these two issues.
