Heh. Yes, and presumably becaues the sim is happy with the offsets from 0
it all works even though it hasn't been relocated.

As for why it didn't work without being full linked, I would say that for:

arm-elf-gcc -Wl,--gc-sections -o test test.o -nostdlib

if you aren't linking in crt0.o (due to -nostdlib) then there's no
reference to main. The tools should complain, but for some reason they
aren't.

This is off-topic for the eCos list anyway.
