In Thumb1 mode, bl instruction might be selected for branches between basic blocks in the function if the offset is greater than 2KB. However, this might cause SEGV because the destination symbol is not marked as thumb function and the execution mode will be reset to ARM mode. Since we are sure that these symbols are in the same data fragment, we can simply resolve these local symbols, and don't emit any relocation information for this bl instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200842 91177308-0d34-0410-b5e6-96231b3b80d8
