Tablegen's -gen-instr-info pass has a bug in its emitEnums() routine. The function intends for values in a vector to be deduplicated, but it accidentally skips over elements after performing a deletion. I think there are smarter ways of doing this deduplication, but we can do that in a follow-up commit if there's interest. See the thread: [PATCH] TableGen InstrMapping Bug fix. Patch by Tyler Kenney! llvm-svn: 288408
