           Summary: llvm-objdump print wrong function symbol of b
                    instruction
           Product: new-bugs

llvm-objdump print wrong symbol of b instruction(or other b instructions):

$ cat testb.s 
 .syntax unified
 .section .text, "ax",%progbits
 .globl _start
 .type _start,%function
_start:
 b   func

.global func
.type func,%function
func = 0x2000

llvm-mc -arm-add-build-attributes -filetype=obj
-triple=armv7a-none-linux-gnueabi testb.s -o testb.o

$ llvm-objdump -d testb.o

testb.o:        file format ELF32-arm-little

Disassembly of section .text:
0000000000000000 _start:
       0: fe 07 00 ea                   b       #8184 <_start+0x2000>

but it's wrong when adding triple:

llvm-objdump -d -triple=thumbv7a-linux-gnueabihf testb.o

testb.o:        file format ELF32-arm-little

Disassembly of section .text:
0000000000000000 _start:
       0: fe 07 00 ea                   b       #8184 <_start+0x1ffc>
