From: Sven Schnelle <sv...@stackframe.org>
It looks like the operands where exchanged. HP bootrom tests the
following sequence:
0x00000000f0004064: ldil L%-66666800,r7
0x00000000f0004068: addi 19f,r7,r7
0x00000000f000406c: addi -1,r0,rp
0x00000000f0004070: addi f,r0,r4
0x00000000f0004074: addi 1,r4,r5
0x00000000f0004078: dcor rp,r6
0x00000000f000407c: cmpb,<>,n r6,r7,0xf000411
This returned 0x66666661 instead of the expected 0x9999999f in QEMU.
