Hello, I have some questions regarding folding operations with symbols during the instruction print stage with MC. At the moment I'm working with global symbols but i guess that other symbol types should be equivalent. My first question is how can i negate the address of a symbol? Consider this piece of code: char g_var[80]; char foo(int a) { return g_var[a]; } this gets compiles into
