-This patch add noinline and noclone attributes to naked functions.
-GCC 4.5 has new optimization -fipa-ira which is enabled at -Os and -O2
-this option will clone the functions and that can change the standard
-calling convention but the naked functions expect that and use
-arguments as in standard calling convention. Therefore the naked
-functions should not be marked non inline and noclone.
