751 | This procedure runs through the native entries in a coff symbol table | |

753 | particular these are: | |
4a81b561 | 754 | |
d6aa3fb0 SC |
755 | strtag, entag and untags have an auxent endindex which points to the |
756 | first syment after the .eos. This is simple to do, we just keep a | |
757 | pointer to the symbol with the most recent pending strtag and patch it | |
758 | when we see the eos. This works since coff structs are never nested. | |
4a81b561 | 759 | |
d6aa3fb0 SC |
760 | ISFCN type entries have an endindex which points to the next static or |
761 | extern in the table, thereby skipping the function contents. | |
762 | The coff book says that an ISFCN's tagindex | |
763 | points to the first .bf for the function, so far I havn't seen it | |
764 | used. We do this using the same mechanism as strtags. | |
4a81b561 | 765 | |
d6aa3fb0 SC |
766 | Each file entry has a value which points to the next file entry, |
767 | the last file entry points to the first extern symbol in the table | |
768 | which is not an ISFCN. | |
4a81b561 | 769 | |
d6aa3fb0 SC |
770 | Each .bb entry points to the matching .eb entry, but these are nested |
771 | so we keep a stack of them. | |
4a81b561 | 772 | |
d6aa3fb0 SC |
773 | The tagndx of .eos items points to the strtag attached to them, this |
774 | is simply the last_tagndx again. | |
4a81b561 | 775 | |
d6aa3fb0 SC |
776 | The tagndx of items with type strtag point to the defining struct. |
777 | This bit is complicated; We know that a struct ref and def must be | |
778 | within the same file, so all the natives will be in the same vector. | |
779 | This means that we can subtracts two pointers and get the index | |
780 | differences between to items, used to work out the true index of the | |
781 | target. | |
4a81b561 | 782 | |
d6aa3fb0 | 783 | We store in the name field of each syment the actual native index |
fc723380 | 784 | applied so we can dig it out through a pointer. */ |
