The rbelf shows some slight increase in size but the overall effect should be negligible (those functions should be called by cold functions themselves most if not all the time). Patch fine for me (should speed up compiling a little and recompiling a lot as positive tradeoff) (GCC reports cold to do slightly different things, one part of the documentation pretty much makes it similar to the builtin_expect/unlikely the other describes it closer to call-once/seldom) lu _______________________________________________ libav-devel mailing list [email protected] https://lists.libav.org/mailman/listinfo/libav-devel
