--- Comment #2 from Matthias Klose <doko at gcc dot gnu.org> ---
is this about stability? With trying, you find out that the following will
work:

#include <gcc-plugin.h>
#include <tree.h>
#include <function.h>
#include <basic-block.h>
#include <coretypes.h>
#include <is-a.h>
#include <predict.h>
#include <internal-fn.h>
#include <tree-ssa-alias.h>
#include <gimple-expr.h>
#include <gimple.h>

int main(void) {
        return 0;
}


is there any way to find out all the needed includes?  Telling plugin writers
to hard-code all of this doesn't seem like a viable solution.
