 * BUG:PR64431 (easy difficulty)

Be sure to first read the basic steps for Contributing to GCC.

These bugs (also called Problem Reports) are great starting points for new contributors to GCC. If you have doubts or questions, don't be afraid to ask in the bugzilla page of each bug.

There is also a non-wiki list of beginner projects at http://gcc.gnu.org/projects/beginner.html, however, it is very outdated and the projects are not that easy.

Other easy projects without a PR are (you can help by opening a PR for them and moving them to the list above):

  • Delete unused variables and functions. A list of potential candidates is here, current as of 2010-05-30. Note that some functions and variables there are not unused, for example, debugging output helpers.

  • Constify read-only variables. A list of potential candidates is here, current as of 2010-05-30.

  • Change the vectors in genautomata.c to be sbitmaps instead of the current adhoc implementation.
