A Maintenance Programmer's View of GCC

Version 2

    GCC is considered more difficult to modify or debug than other programs of  similar size. This paper will investigate the reasons for this  difficulty, from the point of view of a maintenance programmer: someone  producing a small patch to fix a bug or implement a feature, without  causing new problems for unrelated use. Because the development tree’s  head is expected to be functional at all times, such incremental changes  are normal—even regular contributors are in the  maintenance  programmer’s shoes.
