[Qemu-devel] [PATCH risu v2 1/3] ppc64.risu: Add missing byte and dword loads

[Sandipan Das]

The patterns for the following instructions are added:
 * Load Byte and Zero (lbz)
 * Load Byte and Zero with Update (lbzu)
 * Load Byte and Zero Indexed (lbzx)
 * Load Byte and Zero with Update Indexed (lbzux)
 * Load Doubleword (ld)
