Hi Pali, Hi Richard,
Having file name and line number would be also useful as it took me
some time to figure out where is the issue...
Right - I have tried a little harder and come up with a follow up patch.
This is now checked in, and given an input file that looks like this:
% cat t.s
...

would work:
.word KERNEL_OFFSET + CONFIG_SYS_TEXT_BASE - .
I agree however that this message:
t.s: Error: attempt to get value of unresolved symbol `L0'
is unhelpful. So I am going to check in a patch to change it to:
t.s: Error: expression is too complex to be resolved
I

{standard input}: Assembler messages:
{standard input}: Error: attempt to get value of unresolved symbol `L0'
I do not use any L0 symbol in the code, so error message seems to be
incorrect. And also I do not think
