- The `ldloca.s` instruction pushes the address of the local variable number at the passed index onto the stack, where local variables are numbered 0 onwards. The value pushed on the stack is already aligned correctly for use with instructions like <xref:System.Reflection.Emit.OpCodes.Ldind_I> and <xref:System.Reflection.Emit.OpCodes.Stind_I>.
