35 | The octet order is screwy. words are LSB first (LS octet, actually), but | |
36 | longwords are MSW first. For example, 0x12345678 is encoded 0x5678 in the | |
37 | first word and 0x1234 in the second. When looking at the data as stored in | |
38 | the COFF file, you would see the octets ordered as 0x78, 0x56, 0x34, 0x12. | |
39 | Don't bother with 64-bits, as there aren't any. | |
