Byteplay-Python bytecode Assembler-disassembler-Google Project hosting Byteplay lets you convert Python code objects into equivalent objects which are easy to play with, and lets you convert those objects back into living Python code objects. it's useful for applying crazy transformations on Python functions, and is also useful in learning Python byte code intricacies. check the documentation to see it in action!

Original address: http://oss.org.cn/kernel-book/ch02/2.6.1.htm ----------- Comparison of 2.6.1 and Intel assembly language We know that Linux is a member of the Unix family, and although the history of Linux is not long, many of the things associated with it originate from UNIX. In terms of the 386 assembly language used by Linux, it also originated from UNIX. UNIX was originally developed for PDP-11, and has been ported to the VAX and 68000 series processors, and the assembly language on these

value, not an absolute address, and its Values are computed by the assembler (relative addressing in the reference addressing method). It is a 24-bit signed number, the left two-bit symbol expands to 32-bit, and the valid offset is 26 bits (the address space of the front and back 32MB). The following directives:# The program unconditionally jumps to the label label to execute B Label; When the z-condition code is set in the #当CPSR register, the prog

Statements in assembly language programs can be composed of commands, pseudo commands, and macro commands. Command: Each Command corresponds to a CPU operation. A pseudo-command is also called a pseudo-operation. It is an operation processed by the assembler during the compilation of the source program, they can complete functions such as processor selection, defining program patterns, defining data, alloca

Compiler built-in macros: First, we will introduce several built-in macro definitions of the compiler. These macro definitions can not only help us write cross-platform source code, but also help us output useful debugging information flexibly. The ansi c standard has several predefined macros (which are also commonly used ): _ Line __: Insert the current source code line number into the source code; _ File

The macro definition is one of the three preprocessing features provided by C, and these three preprocessing include: macro definition, file inclusion, conditional compilation1macro Definition without parameters: Macro definition is also called macro substitution, macro subs

Brief introduction: In this paper, we propose an architecture mode-interface assembler mode in interface design, it is committed to the decomposition of the interface, the interface and assembly behavior decoupling, the interface logic processing and domain logic to understand the decoupling, so that we develop GUI rich Client interface application can be from a large number of interface control management, and focus on my The development of the back

Macros are very rich, and if you just do a small database, the process of the program can be fully implemented with macros, without using Visual Basic. Some operations have no parameters (such as Beep), while others must specify parameters (such as OpenForm). In general, it is a good practice to set the parameters of an operation in the order of the parameters, because selecting a parameter determines the selection of the parameters that follow the parameter. Common
