Last active June 11, 2021 06:13

C/C++ performance magic functions (prevent optimization)

	/**
	* Those functions are related to: https://www.youtube.com/watch?v=nXaxk27zwlk&t=2446s
	*
	* They are used to allow to benchmark functions with -O3 that would otherwise be removed because it is unused.
	*
	* escape(&object) prevents object to be optimized out
	* "This ASM code has some unknowable side effects and possibly stored the pointer globally"
	* clobber() tells the compiler some asm might be reading the whole memory
	* "This ASM code could probably read/write to all memory" => observe all memory
