Can you provide a way to reproduce this problem ?
I tried to reproduce it using the script you supplied, but the symbol
appeared in the symbol table:
% cp hello.o lexthread.o
% cp hello.o lexunix.o
% arm-ld hello.o -T johns_script.t
warning: cannot find entry symbol _start; defaulting to 0000000000008000
% nm a.out
00000000005a0054 T lexunix_prefetch1_end
00000000005a0054 A lexunix_prefetch1_start
00000000005a0054 T lexunix_prefetch2_end
00000000005a0054 T lexunix_prefetch2_start
00000000005a0054 T lexunix_prefetch_end
00000000005a0054 A lexunix_prefetch_start
00000000005a0054 t my_variable
00000000005a0078 t my_variable
00000000005a009c t my_variable
This was using the current binutils mainline sources, rather than the
2.17 release sources, so it is possible that there was a bug that has
now been fixed.
Cheers
Nick
