inlining

[Styopa Semenukha]

I suppose they will be inlined at -O2 level:
http://linux.die.net/man/1/gcc

-finline-small-functions
Integrate functions into their callers when their body is smaller than expected function call code (so overall size of program gets smaller). The compiler heuristically decides which functions are simple enough to be worth integrating in this way.
Enabled at level -O2.
