[avr-gcc-list] avr-as and symbolic debugging in AVR Studio 4

[Brian Cuthie]

Has anyone been able to symbolically debug avr-as assembled files in AVR
Studio 4?  I'm using the WinAVR binutils avr-objcopy that converts from
elf to coff file formats. I've looked at the .stab sections of the file
and they look ok. But objcopy complains about a number of things. 

Here's the file I'm assembling:

        
        .file   "demo.s"
        
        .stabs  "f:/temp/",100,0,0,Foo
        .stabs  "demo.s",130,0,0,0
        
        .section  .text

        .func   Foo
        .global Foo
        
Foo:
        cli
        rjmp    Foo
        
        .endfunc
        

Using the command:

avr-as --gstabs -a -mmcu=atmega16 -o demo.o demo.s

Output from the assembler looks fine, but when I run objcopy, I get the
following error:

F:\Temp>avr-objcopy --debugging -O coff-ext-avr demo.o demo.coff
Warning: file f:/temp/ not found in symbol table, ignoring
Warning: ignoring function Foo() outside any compilation unit


Anyway, I'm at wit's end. If anyone can help, I'd appreciate it.

Thanks
