[Qemu-devel] [Bug 595906] [NEW] [ARM] All variants of ADDSUBX, SUBADDX give incorrect results |

Public bug reported:
All variants of the ADDSUBX/SUBADDX instructions seem to be implemented
incorrectly, i.e.
MOV r12, #0
LDR r0, =0x18004800
LDR r1, =0x30006000
QADDSUBX r12, r0, r1 ; Should give 0x78001800 - gives 0x4800e800
This happens with latest git HEAD.
