I propose to make the following change to clang.
In the presence of the "naked" attribute, in cases where clang would
normally implicitly emit a "return" instruction, it should emit an
If someone explicitly puts a C/C++ "return" statement in the code, clang
should do what it normally does.
The semantics of the "naked" attribute forbid the compiler from emitting
a (implicit) return statement, prologue and epilogue code. The
presumption is that there is only inline assembly in such a function but
that is not a requirement but the programmer must know what he/she is
doing and realize the rest of the above.
If this reasonable I'll file a clang bug and maybe fix it myself if
it's obvious where to do this.
