SEND-PR: critical GCC is completely not operational; no work-around known. SEND-PR: serious GCC is not working properly; a work-around is possible. SEND-PR: non-critical Report indicates minor problem. SEND-PR: medium The problem should be solved in the next release. SEND-PR: low The problem should be solve in a future release. SEND-PR: doc-bug The documentation is incorrect. SEND-PR: accepts-illegal GCC fails to reject erroneous code. SEND-PR: rejects-legal GCC gives an error message for correct code. SEND-PR: wrong-code The machine code generated by gcc is incorrect. SEND-PR: ice-on-legal-code GCC gives an Internal Compiler Error (ICE) SEND-PR: for correct code SEND-PR: ice-on-illegal-code GCC gives an ICE instead of reporting an error SEND-PR: pessimizes-code GCC misses an important optimization opportunity SEND-PR: sw-bug Software bug of some other class than above SEND-PR: change-request A feature in GCC is missing. SEND-PR: support I need help with gcc.
