(derived from how our implementation behaves).
Does this look ok?
Thanks,
Richard.

Generally, functions are not inlined unless optimization is specified.
-For functions declared inline, this attribute inlines the function even
-if no optimization level is specified.
+For functions declared inline, this attribute inlines the function

+Failure to inline such a function is diagnosed as an error.
+Note that if such a function is called indirectly the compiler may
+or may not inline it depending on optimization level and a failure
