This is the easiest question for me, so I answer it first.
In asm-source.exp, first comes:
set asm-flags ""
After all target things, there is:
if { "${asm-flags}" == "" } {
set asm-flags "-I${srcdir}/${subdir} -I${objdir}/${subdir}"
set debug-flags "-gstabs"
}
So if target does not set asm-flags, the debug-flags will be set to
"-gstabs", which will override anything target set for it. If any
target want to use dwarf2 as debug information, like bfin and others,
it needs set asm-flags to the vanilla string to avoid the overriding.
Regards,
Jie
