--- Comment #4 from Martin Sebor <msebor at gcc dot gnu.org> ---
The original -Wnonnull implementation was done in the front end, making it
nearly useless (bug 17308). To improve it, the enhancement committed in
r243661 did the checking very late (in calls.c). The initial commit triggered
a flurry of warnings during bootstrap (bug 78817) due to various limitations in
GCC's optimization passes, which ultimately led to moving the implementation to
a much earlier stage where it doesn't benefit from some of the useful
optimizations that are done later.
