Re: Weeding out unwanted include files

Along these same lines, a tool which would generate a symbol usage DAG
for an entire (very large) program could be extremely valuable.


For example:


----bar.h-------
#define SOME_VALUE 8


----foo.c-------


include "bar.h"


int global1;


foo()
{
    global1 = SOME_VALUE;
}


main()
{
    if (global1 == foo())
        ....
}
----------------------------------
Would produce something like this:


foo.c:main() -> foo.c:foo()
foo.c:global1;
foo.c:foo() -> foo.c:global1;
bar.h:SOME_VALUE
----------------------------------


For analyzing old code this kind of information could potentially
save you all kinds of grief. So does anyone have some time to
modify gcc and a linker???
