arm-linux-gcc的命令参数介绍（国外英文资料） We need to compile the code that runs on the ARM platform, using the cross-compiler for arm-linux-gcc. The following are some common command parameters for the arm-linux - GCC compiler. Prior to this, the process of compiling the compiler was introduced, and the compilation process was divided into four phases when using the GCC compiler: Pre-processing (pre-processing) Compile (compile) 3. Assembly (Assembling) Link (Linking) Linux programmers can need according to oneself make GCC at any stage during the compilation of the end, in order to check or use the compiler in the phase of the output information, or to control the last generated binaries, so that by adding different amount and type of debugging code to prepare for future debugging. Like other commonly used compilers, GCC provides flexible and powerful code optimization capabilities that can be used to generate code that executes more efficiently. Take the example of the file example Arm-linux - GCC - o example Without the -c, -s, -e parameters, the compiler will perform preprocessing, compilation, assembly, and connection operations to generate executable code directly. The -o parameter is used to specify the output file, the output file is called example, and if the output file is not specified, the default output a.ut is the default output Arm-linux - cgs-c-o example.o The -c parameter will preprocess, compile, and compile the source program example.write the example.o file Remove the specified output option -o example.o automatically output as example.o, so you can do it here Example: arm-linux - gcc-s-o example.s The -s parameter will preprocess, compile, and generate the example.s file -o ditto -- -- -- -- -- -- -- -- -- -- The -e parameter will preprocess the source program example.generate the example.i file (different versions, some print the preprocessed content onto the screen) This is to do file insertion and macro extensions such as # include, # define, etc. Arm-li
