message, and the selector of T He method that handles the message. Objc_msgsend () takes the ID type, which is literally just a pointer to a C struct, being identified as Objc_object. After a object is created, memory was allocated for the Objc_object type that consists if a ISA pointer, which is Followe D by the data for that object. In this usage, the ID of type is basically a pointer to the receiver's class instance in memory.The second argument SEL, is pretty much the method ' s signature s

the outer label. In R7, the VPN label is stripped. there are two tags in total. configuration case: the topology is as follows: Of course, the packet encapsulation and forwarding process is described in the experiment, and related configurations are attached. 1. When the RD of the two ends of the PE is different in the principle section, when the two RD ends are the same, they will not be maintained as the same routing Prefix: Let's look at the tag a

translator presses: that is, either the transit interface activates MPLS).This case shows how to: on the ingress router (R1), use R7 's loopback port address (10.0.9.7) to define an LSP from R1 to R7. 10Mbps bandwidth is reserved for MPLS in the following configuration. Additionally, this configuration disables the CSPF algorithm to ensure that the rsvp-signaled LSP used by the host C1 and C2 is consistent

B, like no b is called). In the above illustration, a stack frame has a stack frame pointer storage area (saved frame pointer) in addition to the already mentioned parameter region (parameter area), Link region (linkage area), and local variable storage (area storage). Register store (saved registers area), the stack frame register is no longer explained, register Store: Save nonvolatile Register (R4,R5,R6,R8,R10,R11), the following assembly code examples will be introduced. Start Call (Fie

. Address. Base Address addressing is used to access storage units near the base address. It is often used for table queries, Array Operations, and access to non-register functions. Q Example: LDRR2, [R3, # 0x0c]; Read the content of the storage unit pointed to by the R3 0x0c address, and put it in R2 StrR1, [r0, #-4]!First R0 = R0-4, and then store the value of R1 to the Unit pointed to by R0 LDRR1, [r0, R3, LSL #1]Read the content of the Unit on R0 R3 * 2 and store it in R1. 6. Relative addres

The problems that arise: A) R1 has a 7.7.7.0/24 route on it, but Ping 7.7.7.7 is not reached. (R7 same) Now view the R1 routing table R7#sh IP route B 1.1.1.0 [20/0] via 5.5.5.5, 00:02:54/To save space incomplete display It can be seen that R7 learned the route of the R1, from the surface to see the experiment is perfect, for the purpose, but then the proble

the address pointer of the operand. Examples of indirect addressing commands in registers are as follows:LDR R1, [R2]; reads the data of the storage unit pointed to by R2. stores the data in R1.SWP R1, R1, [R2]; exchange the value of register R1 with the content of the storage unit pointed to by r2 5. Multi-register addressingMultiple register addressing can transmit several register values at a time, allowing one instruction to transmit any subset or all registers of 16 registers. Examples of

immediate number (24 bits low ). The following code can be found in entry-common.S. In section 2.6.21, you will find that you cannot avoid this concept. What is Eabi? In the kernel, the interview with Eabi and oabi is actually relative to the method of system calling. Of course, the system we call is limited to the arm system.Eabi (Extended Abi) is a new method of calling the system. MoV R7, # numSWI 0x0 The original system call method is as follows

right is after the call. When B returns, it should return to the Left State (A is before B is called, just like calling B ). In a stack frame, apart from the previously mentioned parameter area, link area, and local storage area) besides, the stack frame pointer storage area (saved frame pointer) and the register storage area (saved registers area) have been introduced above (R7); the register storage area: save non-loss-prone registers (R4, R5, R6,
