PRIMESSTEP2 Sample: Demonstrates a Mixed C and ASM Project

The PRIMESSTEP2 sample is a mixed C and ASM project that moves the core algorithm to the .asm file. The extern function and global data structure are separately declared in the .c file and the .asm source file.

In the .asm source file, the settings for the Command Line and Outputs boxes of the Custom Build Step tab are included in comments. To view these settings, right-click the .asm file and click Properties. These settings, which support including the .asm file in the build, have already been entered for you.

Building and Running the Sample

To build and run this sample

  1. Open the solution PrimesStep2.sln.

  2. On the Build menu, click Build.

  3. On the Debug menu, click Start Without Debugging.

You can use this sample to explore Visual C++ support for mixed C/C++ and ASM projects, such as using the Custom Build Step tab in the Properties dialog box and debugging .asm files at a source level. You can use the .asm file or project file as a template to incorporate .asm files into a Visual C++ project.
