/* 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. */
