| /* The following is written to tickle a specific bug in the macro |
| table code (now hopefully fixed), which doesn't insert new included |
| files in the #including file's list in the proper place. They |
| should be sorted by the number of the line which #included them, in |
| increasing order, but the sense of the comparison was reversed, so |
| the list ends up being built backwards. This isn't a problem by |
| itself, but the code to pick new, non-conflicting line numbers for |
| headers alleged to be #included at the same line as some other |
| header assumes that the list's line numbers are in ascending order. |
| |
| So, given the following input, lineinc1.h gets added to lineinc.c's |
| #inclusion list first, at line 10. When the debug info reader |
| tries to add lineinc2.h at line 10 as well, the code will notice the |
| duplication --- since there's only one extant element in the list, |
| it'll find it --- and insert it after lineinc1.h, with line 11. |
| Since the code is putting the list in order of descending |
| #inclusion line number, the list is now out of order. When we try |
| to #include lineinc3.h at line 11, we won't notice the duplication. */ |
