| /* |
| * 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. |
