>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'.
