Hello

Im using a ld script for my ROM-project. Therfore i am defining some
symbols and calculating load addresses. Here is an excerpt:

SECTIONS
{
	rom_off = 0x0;
	rom_map_start = 0xfff00000;

	ROM_legacy_start = rom_map_start + rom_off; 
	. = 0xe0000;

	_text = .;
	.text : AT (rom_off) {
...


But 0x0 + 0xfff00000 should be 0xfff00000, but why has ROM_legacy_start a
different value ?

Here the map file:

0x0000000000100000                rom_size = 0x100000
0x0000000000000000                rom_off = 0x0
0x00000000fff00000                rom_map_start = 0xfff00000
0x00000000fff1350f                ROM_legacy_start = (rom_map_start + rom_off)
0x00000000000e0000                . = 0xe0000
0x00000000000e0000                _text = .

.text           0x00000000000e0000    0x10a49 load address 0x000000000001350f


im using "GNU ld version 2.15". Thanks in advance
