What makes you think it will be expensive? I don't know much about
clang internals, but I think something has to provide a mangled name
in any case. So, if we don't specify a mangled name, clang will have
to do the mangling itself. For all I know, setting the asm attribute
may actually speed things up, as clang could avoid doing some extra
work.

I think it would be interesting to try to measure the
performance/memory footprint impact of just setting the asm attribute
everywhere.
