--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> --- [apinski@xeond2 gcc]$ git grep needs_preprocessing gcc.cc: int needs_preprocessing; /* If nonzero, source files need to lto/lang-specs.h: /*cpp_spec=*/NULL, /*combinable=*/1, /*needs_preprocessing=*/0}, That is the only references that grep could find even for needs_preprocessing.
