I=E2=80=99m not disagreeing that inline ll/sc is more efficient on =
systems that support it.  But if the compiler is targeted at a MIPS-I =
target, this is generally considered an acceptable compromise.  Sure, if =
you build with -mmips3 or whatever the flag is, inline it.  But if =
-mmips1, a libcall doesn=E2=80=99t seem unreasonable.
