[Bug gas/3109] New: GAS assembles incorrect branches using target arm-wince-pe

[boris dot leidner at formenos dot de]

I assembled the following code:
.text
        .global _start
_start:

        mov r1, r1
        b _start
.end

$ arm-wince-pe-as armtest.s -o armtest.o

$ arm-wince-pe-objdump -d armtest.o

armtest.o:     file format pe-arm-little

Disassembly of section .text:

00000000 <_start>:
   0:   e1a01001        mov     r1, r1
   4:   ea000000        b       8 <_start+0x8>

GAS produces incorrect code for branches, at least sometimes. GDB for
arm-wince-pe says:

(gdb) disas _start
Dump of assembler code for function _start:
0x00000000 <_start+0>:  mov     r1, r1
0x00000004 <_start+4>:  b       0xc

I do not know why GAS and GDB disassemble code differently, but the real problem
is, that the branches are not working when I execute the code.
