61 | * Notes on COFF: |
62 | * |
63 | * (0) When I say `standard COFF' below, I mean `COFF as output and |
64 | * used by DJGPP'. I assume DJGPP gets it right. |
65 | * |
66 | * (1) Win32 appears to interpret the term `relative relocation' |
67 | * differently from standard COFF. Standard COFF understands a |
68 | * relative relocation to mean that during relocation you add the |
69 | * address of the symbol you're referencing, and subtract the base |
70 | * address of the section you're in. Win32 COFF, by contrast, seems |
71 | * to add the address of the symbol and then subtract the address |
72 | * of THE BYTE AFTER THE RELOCATED DWORD. Hence the two formats are |
73 | * subtly incompatible. |
74 | * |
75 | * (2) Win32 doesn't bother putting any flags in the header flags |
76 | * field (at offset 0x12 into the file). |
77 | * |
78 | * (3) Win32 uses some extra flags into the section header table: |
79 | * it defines flags 0x80000000 (writable), 0x40000000 (readable) |
80 | * and 0x20000000 (executable), and uses them in the expected |
81 | * combinations. It also defines 0x00100000 through 0x00700000 for |
82 | * section alignments of 1 through 64 bytes. |
83 | * |
84 | * (4) Both standard COFF and Win32 COFF seem to use the DWORD |
85 | * field directly after the section name in the section header |
86 | * table for something strange: they store what the address of the |
87 | * section start point _would_ be, if you laid all the sections end |
88 | * to end starting at zero. Dunno why. Microsoft's documentation |
89 | * lists this field as "Virtual Size of Section", which doesn't |
90 | * seem to fit at all. In fact, Win32 even includes non-linked |
91 | * sections such as .drectve in this calculation. |
92 | * |
93 | * Newer versions of MASM seem to have changed this to be zero, and |
94 | * that apparently matches the COFF spec, so go with that. |
95 | * |
96 | * (5) Standard COFF does something very strange to common |
97 | * variables: the relocation point for a common variable is as far |
98 | * _before_ the variable as its size stretches out _after_ it. So |
99 | * we must fix up common variable references. Win32 seems to be |
100 | * sensible on this one. |
