1/* The following is written to tickle a specific bug in the macro 2 table code (now hopefully fixed), which doesn't insert new included 3 files in the #including file's list in the proper place. They 4 should be sorted by the number of the line which #included them, in 5 increasing order, but the sense of the comparison was reversed, so 6 the list ends up being built backwards. This isn't a problem by 7 itself, but the code to pick new, non-conflicting line numbers for 8 headers alleged to be #included at the same line as some other 9 header assumes that the list's line numbers are in ascending order. 10 11 So, given the following input, lineinc1.h gets added to lineinc.c's 12 #inclusion list first, at line 10. When the debug info reader 13 tries to add lineinc2.h at line 10 as well, the code will notice the 14 duplication --- since there's only one extant element in the list, 15 it'll find it --- and insert it after lineinc1.h, with line 11. 16 Since the code is putting the list in order of descending 17 #inclusion line number, the list is now out of order. When we try 18 to #include lineinc3.h at line 11, we won't notice the duplication. */ 19 20#line 10 21#include "lineinc1.h" 22#line 10 23#include "lineinc2.h" 24#line 11 25#include "lineinc3.h" 26 27int 28main (int argc, char **argv) 29{ 30} 31
