VC advanced usage)

The second method of advanced use of VC -- the C code obtains the corresponding assembly code

Add the/FA option in the attachment to generate the corresponding assembly code. asm file in the compiled debug folder. Related parameter settings: /FA[c|s|u] /Fapathname Remarks Parameters Control the generation of source code and machine code and the extension of the list file. The following table describes/FA. Optional/FASpecify multiple values. For example, you can specify/FAsu. Option List content and file extension /FA Assembly Code;. asm /FAc Machine code and assembly code;. cod /FAs Source code and assembly code;. asm If/FACS, The file extension name is. cod. /FAU Causes an output file to be created with a UTF-8 format and byte sequence mark. By default, the file is encoded as ANSI, but if you want the inventory file to be correctly displayed in all systems, or if you want to use the Unicode source code file as the compiler input, use/FAU. If/FasuAnd the source code file uses Unicode encoding other than the UTF-8, the code lines in the. asm file may not be correctly displayed. By default, the configuration file obtains the same base name as the source file. Use/FaYou can change the name of the configuration file and the directory in which the configuration file is created. /Fa usage Result /FA CreateSource_file. Asm. /FA Filename SetFilenamePut. asm in the current directory. Valid only when compiling a single source code file. /FA Filename. Extension SetFilename. ExtensionPut it in the current directory. Valid only when compiling a single source code file. /FA Directory\ CreateSource_file. Asm, and put it in the specifiedDirectory. Note that there must be a suffix backslash. Only the path on the current disk can be used. /FA Directory\Filename SetFilename. Asm is placed in the specified directory. Valid only when compiling a single source code file. /FA Directory\Filename. Extension SetFilename. ExtensionPut it in the specified directory. Valid only when compiling a single source code file.

  Vfdff Of course, you can also use the command:
  The following command line generates a list of combined source code and machine code named HELLO. cod:
  CL/FAcs HELLO. CPP

  You can view the Assembly Code directly when debugging vfdff, but the resulting code has less comments. The ideal method is to use the option/FAs of the VC compiler to generate the corresponding assembly code. /FAs will also add annotations to the assembly code and the correspondence between C ++ code, which is very helpful for analysis. Build code can find the corresponding. ASM file in the output directory.
