Re: gc sections and .eh_frame

Thanks for confirming. However I think I've grasped Alan's remark and we indeed risk marking all the functions in a given input file if it happens to contain no EH tables because its functions don't need them.

I can think of 2 solutions: a second loop as you initially suggested or to add a new parameter 'skip_code' to _bfd_elf_gc_mark to skip SEC_CODE sections when it is invoked on .eh_frame. Alan will decide whether the latter approach is easily implementable.

I think Alan maybe didn't notice his name being mentioned :). Alan, do you have any guidance on the best approach?
