isnt everything that the linker doesnt know where to put it placed in
*(COMMON) ?

yeah sure i know that... but the linker can get that info from the
memory-region the section is assigned to, no? ie, if you dont want to
force any other section than .text to be placed at the start of your
binary, you dont need the AT.

mmh, ive simply declared another memory-region and section for that,
works fine for me ;) (i have to admit i use most of the wram for data,
not code... and all code placed in valuable wram ist handcoded asm so
much less problems with the linker stuff ;=))
