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.
