scenario analysis, and in the first chapter of the book there is an introduction to the mixed programming of C language assembly in GCC, and the compiler used by VxWorks is gcc!You might as well try it out, so you have the following code: /*****************gettsc-get TSC count*************************************

2018-02-10 Nanyi 21CTO Learning programming is to learn high-level language, that is, those designed for human computer language.However, the computer does not understand the high-level language and must be translated into binary code by the compiler before it can be run. Learning a high-level language does not mean un

1. Introduction When C/C ++ and Assembly mixed programming are required, there are two processing strategies: If the Assembly Code is short, you can directly embed the assembly language in the C/C ++ source file to implement mix

Assembly language programming, the 32-bit system should not have any problems, but under the 64-bit system, there will be some different places. Some program samples also compile errors or execute errors.The system used by the blogger is CentOS v6.4 x64. This article mainly solves the 32-bit assembler how to assemble and connect in 64-bit environment, but does no

For college students, basic need to learn advanced programming language, I believe most of the science and technology students know C + +, C, Java language and other high-level language, but also know the machine language of the most low-level

Under Linux, the assembly language uses the/T syntax, which can be used with the GNU tool, including assembler gas, connector ld, compiler gcc, debugger gdb or kdbg,objdump disassembly function, and a profile gprof. A simple example of the use of each tool in assembly language development is described in brief.These to
