Yeah I think GCC should support the __attribute__ style syntax for this
attribute, too

I don't know what the issues are about whether to support __attribute__,

The feature is currently only supported with standard C/C++ attributes

The semantics of -foptimize-sibling-calls do not change. However if your
program depends on sbling calls for correctness it should migrate to the
