S4U:
- the on_exit() of each actor is also executed when the simulation deadlocks.
+C binding:
+ - The return type of the sg_actor_on_exit() callbacks is now 'void'
+ (int value was previously ignored)
+
General:
- LTO is now enabled for Intel/clang compilers.
- LTO behavior on GCC can be parameterized using LTO_EXTRA_FLAG in cmake.
