assembly debug question

["Mike Connors" <mike.connors@ghs.com>]

Hi All, 

I'm using gcc v2.96 to compile a MIPS targeted Linux kernel 
and am finding it difficult to produce debug information 
for assembly files. 

I've discovered that a typical compile line for assembly 
in the kernel gets its parameters from AFLAGS and results 
in the following commandline: 

mipsel-linux-gcc -D__ASSEMBLY__ -D__KERNEL__ -I/l/include \
        -G 0 -mno-abicalls -fno-pic -mcpu=r4600 -mips2 \
        -Wa,--trap -pipe -c entry.S -o entry.o 

According to the documentation, some targets support 
dwarf debug information using --gdwarf2.  Does anyone 
know if the MIPS target is supported in version? 

Also, --gstabs doesn't seem to work either.  Nor does 
-gdwarf-2, -gdwarf -g2, -gstabs+, -gdwarf+, etc. 

Has anyone had luck producing debug information for 
assembly files with this version of gcc? 

./mipsel-linux-gcc --version 
2.96 
./mipsel-linux-as --version 
GNU assembler 2.11.92.0.10 

Thanks in advance, 
Mike
