----
This patch series fixes (and enables by default) the compilation with
link-time-optimization (LTO).
This was tested with gcc-4.8 from https://launchpad.net/gcc-arm-embedded
and results in a 10% code size reduction when compilling with -Os.
Daniel Serpell (3):
Include math function prototypes from the definitions.
Remove memset function, already included as builtin by gcc.
Compile with LTO, gives 10% smaller code.
