yes, and pretty much all of those are emitted implicitly due to math
operations (64bit divs/mults/etc...), or explicitly when the user does
__builtin_xxx() (and use of __builtin_xxx is not affected by -fno-builtins).
none of those that i can see would come via a C library call that gcc would
implicitly rewrite.
