  20 * Generate inline load/store functions for all MMU modes (typically
  21 * at least _user and _kernel) as well as _data versions, for all data
  22 * sizes.
  23 *
  24 * Used by target op helpers.
  25 *
  26 * The syntax for the accessors is:
  27 *
  28 * load:  cpu_ld{sign}{size}{end}_{mmusuffix}(env, ptr)
  29 *        cpu_ld{sign}{size}{end}_{mmusuffix}_ra(env, ptr, retaddr)
  30 *        cpu_ld{sign}{size}{end}_mmuidx_ra(env, ptr, mmu_idx, retaddr)
  31 *        cpu_ld{sign}{size}{end}_mmu(env, ptr, oi, retaddr)
  32 *
  33 * store: cpu_st{size}{end}_{mmusuffix}(env, ptr, val)
  34 *        cpu_st{size}{end}_{mmusuffix}_ra(env, ptr, val, retaddr)
  35 *        cpu_st{size}{end}_mmuidx_ra(env, ptr, val, mmu_idx, retaddr)
  36 *        cpu_st{size}{end}_mmu(env, ptr, val, oi, retaddr)
  37 *
  38 * sign is:
  39 * (empty): for 32 and 64 bit sizes
  40 *   u    : unsigned
  41 *   s    : signed
  42 *
  43 * size is:
  44 *   b: 8 bits
  45 *   w: 16 bits
  46 *   l: 32 bits
  47 *   q: 64 bits
  48 *
  49 * end is:
  50 * (empty): for target native endian, or for 8 bit access
  51 *     _be: for forced big endian
  52 *     _le: for forced little endian
  53 *
  54 * mmusuffix is one of the generic suffixes "data" or "code", or "mmuidx".
  55 * The "mmuidx" suffix carries an extra mmu_idx argument that specifies
  56 * the index to use; the "data" and "code" suffixes take the index from
  57 * cpu_mmu_index().
  58 *
  59 * The "mmu" suffix carries the full MemOpIdx, with both mmu_idx and the
  60 * MemOp including alignment requirements.  The alignment will be enforced.
