Re: Forcing gas not to resolve jump offsets

Hi Alan,


I implemented the tc_fix_adjustable function and told it not to adjust
call/jump targets that are non-local.... problem solved.

The ip2k port has a TC_FORCE_RELOCATION function but it never gets called...
is this anything to worry about?

Thanks again.

You need to do adjust TC_FORCE_RELOCATION for ip2k.  In your case this
means changing tc-ip2k.c:ip2k_force_relocation.  The function should
return 1 for jump target fixups, which you likely can discriminate
from other fixups by looking at the relocation type.  You may also
need to define tc_fix_adjustable to prevent gas converting a fixup
against your jump target symbols to a fixup against a section symbol.
