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

GCC sanitizer with CMake

For memory leaks

Build in CMake with these params:

CMAKE_CXX_FLAGS:STRING= -fsanitize=address  -fsanitize=leak -g
CMAKE_C_FLAGS:STRING=-fsanitize=address  -fsanitize=leak -g
CMAKE_EXE_LINKER_FLAGS:STRING=-fsanitize=address  -fsanitize=leak
CMAKE_MODULE_LINKER_FLAGS:STRING=-fsanitize=address  -fsanitize=leak

Which can be done with:
