Subject: Increment DFAStateEntryTable index for sentinel entry.
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=ffbd0715fa0dd5dd2611cd5cea9f7e5516ba9f5f;p=oota-llvm.git

Increment DFAStateEntryTable index for sentinel entry.

When adding the {-1, -1} entry to the DFAStateInputTable, we
need to increment the index used to populate the DFAStateEntryTable.
Otherwise, the entry table will be off by one for each transition
after the {-1, -1} entry. PR11908.
