- On The AViiON we start the output .text section somewhere after the
- first 64kb (0x10000) of logical address space so that the first
- 64kb can be mapped out, thus catching references through null
- pointers. We actually start at 0x10200 (for efficiency). Ideally,
- we want the page offset of a given word of the .text (output)
- section to be the same as it's page offset in the actual (output)
- linked core file so that paging of the .text section is efficient.
- In order to do this we allow for up to 0x200 bytes of header stuff
- in the output (linked) object file.
-
- For .data, the OCS says that regions with different "protections"
- (i.e. read/write, read-only) should not share any 4 megabyte chunk
- of the logical address space, so we start the .data segment at the
- first (lowest) 4 MB boundary past the end of the .text segment.
-
- For some reason, you can't start right at the 4 MB boundary. You
- have to start at some distance past that. The distance must be
- equal to the distance from the start of the last 64 KB segment in
- the (output) .text segment to the actual end of the (output) .text
- segment. */
