             Bug #: 14095
           Summary: DecodeT2bInstruction in ARMDisassembler.cpp get wrong
                    immediate value
           Product: libraries
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Backend: ARM
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: koviankevin at hotmail.com
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified


by encoding T4 in B instruction
I1 = NOT(J1 EOR S); I2 = NOT(J2 EOR S); imm32 =
SignExtend(S:I1:I2:imm10:imm11:'0', 32);

DecodeT2bInstruction has to be modified by the same method what
DecodeThumbBLXOffset and DecodeThumbBLTargetOperand used in
lib/Target/ARM/Disassembler/ARMDisassembler.cpp
