/*
 * Generate inline load/store functions for all MMU modes (typically
 * at least _user and _kernel) as well as _data versions, for all data
 * sizes.
 *
 * Used by target op helpers.
 *
 * The syntax for the accessors is:
 *
 * load:  cpu_ld{sign}{size}{end}_{mmusuffix}(env, ptr)
 *        cpu_ld{sign}{size}{end}_{mmusuffix}_ra(env, ptr, retaddr)
 *        cpu_ld{sign}{size}{end}_mmuidx_ra(env, ptr, mmu_idx, retaddr)
 *        cpu_ld{sign}{size}{end}_mmu(env, ptr, oi, retaddr)
 *
 * store: cpu_st{size}{end}_{mmusuffix}(env, ptr, val)
 *        cpu_st{size}{end}_{mmusuffix}_ra(env, ptr, val, retaddr)
 *        cpu_st{size}{end}_mmuidx_ra(env, ptr, val, mmu_idx, retaddr)
 *        cpu_st{size}{end}_mmu(env, ptr, val, oi, retaddr)
 *
 * sign is:
 * (empty): for 32 and 64 bit sizes
 *   u    : unsigned
 *   s    : signed
 *
 * size is:
 *   b: 8 bits
 *   w: 16 bits
 *   l: 32 bits
 *   q: 64 bits
 *
 * end is:
 * (empty): for target native endian, or for 8 bit access
 *     _be: for forced big endian
 *     _le: for forced little endian
 *
 * mmusuffix is one of the generic suffixes "data" or "code", or "mmuidx".
 * The "mmuidx" suffix carries an extra mmu_idx argument that specifies
 * the index to use; the "data" and "code" suffixes take the index from
 * cpu_mmu_index().
 *
 * The "mmu" suffix carries the full MemOpIdx, with both mmu_idx and the
 * MemOp including alignment requirements.  The alignment will be enforced.
