1138 | use include: | |
1139 | ||
1140 | addr = align_up (addr, 8); -- VALUE needs 8 byte alignment | |
1141 | write_memory (addr, value, len); | |
1142 | addr += len; | |
1143 | ||
1144 | and: | |
1145 | ||

1147 | write_memory (sp, value, len); | |

1151 | write_memory (addr, value, len); | |
1152 | addr += align_up (len, 8); | |
1153 | ||

1159 | are typically not correct as they don't ensure that the address (SP | |
1160 | or ADDR) is correctly aligned (relying on previous alignment to | |
1161 | keep things right). This is also why the methods are called | |
1162 | "align_..." instead of "round_..." as the latter reads better with | |
