I don't believe musttail has been considered by the C++ standards committee, has it? Right now the Clang attribute is a Clang-only non-standard extension. I believe the backend issues mostly center around DSOs. I am hoping that the dso_local attribute can help out here: https://llvm.org/docs/LangRef.html#runtime-preemption-specifiers https://llvm.org/docs/LangRef.html#runtime-preemption-specif... If musttail only works for functions within the same DSO, that seems sufficient.
