            Bug ID: 114330
           Summary: needs_preprocessing field of struct compiler is unused
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Keywords: internal-improvement
          Severity: enhancement
          Priority: P3
         Component: driver
          Assignee: unassigned at gcc dot gnu.org
          Reporter: pinskia at gcc dot gnu.org
  Target Milestone: ---

I suspect needs_preprocessing  field became unused when the C preprocessor
became itergrated into the cc1.

while it does not hurt anything to have the field still around and only the
".c" sets it to true, it seems like a decent idea to remove the field.

Also note it might be useful to boolize combinable in struct compiler in gcc.cc
too.
