![]() Linear scan regalloc is currently assuming that any register aliased with a member of a regclass must also be in at least one regclass. That is not always true. For example, for X86, RIP is in a regclass but IP is not. If you're unlucky, this can cause a crash by invalidating the iterator. llvm-svn: 124365 |
