qemu-e2k/target-ppc/op_mem_access.h
j_mayer e7c240035f Add new sane low-level memory accessors for PowerPC that do proper
size or zero extension, with homogenous names.
Fix load & store strings: those are now endian-sensitive, by definition.
Fix dcbz: must always align the target address to a cache line boundary.
