Paul Mackerras 350779a29f powerpc: Handle most loads and stores in instruction emulation code ... This extends the instruction emulation infrastructure in sstep.c to handle all the load and store instructions defined in the Power ISA v3.0, except for the atomic memory operations, ldmx (which was never implemented), lfdp/stfdp, and the vector element load/stores. The instructions added are: Integer loads and stores: lbarx, lharx, lqarx, stbcx., sthcx., stqcx., lq, stq. VSX loads and stores: lxsiwzx, lxsiwax, stxsiwx, lxvx, lxvl, lxvll, lxvdsx, lxvwsx, stxvx, stxvl, stxvll, lxsspx, lxsdx, stxsspx, stxsdx, lxvw4x, lxsibzx, lxvh8x, lxsihzx, lxvb16x, stxvw4x, stxsibx, stxvh8x, stxsihx, stxvb16x, lxsd, lxssp, lxv, stxsd, stxssp, stxv. These instructions are handled both in the analyse_instr phase and in the emulate_step phase. The code for lxvd2ux and stxvd2ux has been taken out, as those instructions were never implemented in any processor and have been taken out of the architecture, and their opcodes have been reused for other instructions in POWER9 (lxvb16x and stxvb16x). The emulation for the VSX loads and stores uses helper functions which don't access registers or memory directly, which can hopefully be reused by KVM later.
