[U-Boot-Users] gdb with u-boot: can not locate the source fil es

[Xiao Xianghua-r6aads]

Yes I'm using a self-compiled gdb because I need to use the BookE instructions. I found that after I disabled 'Wa,gstabs' argument in config.mk then neither DDD nor GDB will complain, and the traps.c will be loaded into DDD automatically. However 'start.S' and other '*.S' still could not be shown in the DDD window. I can now source-debug all *.c except *.S though.

At least, my GDB does not work well with 'Wa,gstabs'. When I looked at Linux kernel compilation screen output, I found they didn't use this flag for arch/ppc/kernel/*.S either. Why should we set 'Wa,gstabs' as default for those assembly source files in U-Boot?

Thanks a lot,

Xianghua
