functions. This pointer is stored in the Cx register and the parameters are pressed from right to left. _ Fastcall: it transmits parameters through registers (in fact, it uses ECx and EDX to transmit the first two DWORD or smaller parameters, the rest of the parameters are still transferred from the right to the left pressure stack, and the called function pops up the parameter stack before returning ). For more detailed call conventions, refer to ca

Recently, I saw the Delphi Program for a lifetime of component graphics on the Internet. The generated graphics are very beautiful, so I changed it to C ++ and improved the generation efficiency. The Code is as follows (the original code uses the plural operation and is removed for efficiency, but is still kept in the comment) // This function is used to obtain the color. S is between [0, 1] and the color is continuous. Colorref getcolor (double S) { Int R, G, B; If (s { G = int (255 * s/0.25 );

For C ++, function overloading exists, for example: void CCNode::setScale(float scale)void CCNode::setScale(float scaleX,float scaleY) The two functions have the same name, but different parameter tables. Finally, the function signature after compilation is different. However, this mechanism does not exist in JavaScript. How can this problem be solved? There are two situations: First, JS needs to call the overloaded C ++ function interface Let's take the above functions as an example to see h

. Instructions The assembler uses a variety of directives to bind text and data to symbol names. For example, here is a simple but complete function definition. The TEXT directive declares the symbol runtime Profileloop, which is immediately in the body similar to the function. The end of the TEXT block must be some form of jump, usually a RET(pseudo) instruction. (if not, the linker appends an instruction that jumps to the block itself, theTEXT block does not have a fallthrough) after the symbo

32-bit CPUs contain the following registers: Four data registers (eax, EBX, ECx, and EDX)2 address changes and pointer registers (ESI and EDI) 2 pointer registers (ESP and EBP)Six segment registers (ES, Cs, SS, DS, FS, and GS)1 Instruction Pointer register (EIP) 1 flag register (eflags) 1. Data RegisterData registers are mainly used to save information such as the operands and operation results, thus saving the time required to read the operands by occupying the bus and accessing the memory.The
