Subject: [openrisc] Bug in hello-uart
Hi!I'm not sure, whether this is the right mailing list, but there is a
tricky bug in the hello-uart example program of or1k:
Index: hello-uart/reset.S

- l.addi r2,r0,-3
+ l.addi r2,r0,-4
l.and r1,r1,r2
l.movhi r2,hi(_main)
I suppose that the -3 should do an alignment to 32bit words but this is
not the case. Because -3 is b1101 or 0xD so it should be -4 equal to
b1100 or 0xC. Could somebody please confirm this?
Regards,
Patrick
