Hi, all I'm compiling project using gcc, it generate dwarf info : ... <74cb> DW_AT_name : (indirect string, offset: 0x1a6a): board.c<74cf> DW_AT_comp_dir : (indirect string, offset: 0x2689): /root/file/u-boot/u-boot-am33x/arch/arm/lib
...what option should be add to change DW_AT_name from "board.c" to "/root/file/u-boot/u-boot-am33x/arch/arm/lib/board.c" ? which means DW_AT_name contains full path of the source file?
