Branch instructions(b/bl) for ARM

["=?EUC-KR?B?t/m47cjx?=" <mega74 at hanmail dot net>]

Dear Binutils

I was checked the elf file.

same as a "arm-elf-objdump -dr crt0.o" instruction.

But, result like this :
=====================================================================
crt0.o:     file format elf32-littlearm

Disassembly of section .text:

=====================================================================

compile options follow this
  --target=arm-elf --disable-threads --with-newlib 
  --with-headers=/usr/src/linux/include

but, b/bl instructions branch the recursive like folllow:
============================================================
00000000 <_mainCRTStartup>:

  28:	ebfffffe 	bl	28 <_mainCRTStartup+0x28>
			28: R_ARM_PC24	memset
  2c:	ebfffffe 	bl	2c <_mainCRTStartup+0x2c>
			2c: R_ARM_PC24	initialise_monitor_handles


0000009c <LC13>:

  b4:	ebfffffe 	bl	b4 <LC13+0x18>
			b4: R_ARM_PC24	main
  b8:	ebfffffe 	bl	b8 <LC13+0x1c>
			b8: R_ARM_PC24	exit
============================================================

Why was happend above problem?
Pleaswe, Help me.
