LGTM, this would be very useful for assembly files, since I believe most developer won't write attribute when writing assembly code, and `arch` attribute is also kind of hard to write it correctly  by human - and it even need to sync with build system (`-march` option for assembler)! so I believe auto generate that is right way to go.
