Subject: objdump disasm on kernel -- not working
Content-Type: text/plain; charset=us-ascii
Content-Transfer-Encoding: 7bit

I've been trying to use GNU objdump to get a dump
of a FreeBSD kernel, but it seems to miss the symbolic 
names of the routines:

$ objdump -d kernel | head

kernel:     file format a.out-i386-freebsd

Disassembly of section .text:
00000000 <_btext-f0100000> movw   $0x1234,0x472
00000009 <_btext-f00ffff7> pushl  %ebp
0000000a <_btext-f00ffff6> movl   %esp,%ebp
0000000c <_btext-f00ffff4> pushl  $0x2
0000000e <_btext-f00ffff2> popf   
0000000f <_btext-f00ffff1> movw   %ds,%ax

And we all know that the initial routine should be _start.  :-)
Why the btext???

Now, I know the kernel debugger, ddb, prints out a listing with syms.
But that's a little bit slow to do since it's on a serial port.

Any suggestions?
