From 60e29463bbfcf72500c00eb102d1c388c87057ba Mon Sep 17 00:00:00 2001 From: Sven Schnelle Date: Mon, 11 Feb 2019 19:19:07 +0100 Subject: target/hppa: fix dcor instruction 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.
