>From GCC's own manual:
(Node "Function attributes"):
On the 386/x86_64 and PowerPC backends, the inliner will not
inline a function that has different target options than the
caller, unless the callee has a subset of the target options of
the caller. For example a function declared with `target("sse3")'
can inline a function with `target("sse2")', since `-msse3'
implies `-msse2'.
