C-code to DSP asm file conversion..

In your project build options, go to the compiler settings and set the -save-temps switch. This will instruct the compiler to save the compiler-generated assembly code in your output directory (the same directory that your output file goes to, whether it is /Debug, /Release, or a custom configuration that you've created). It will appear as the same file name of the C source file with a .s extension. If you then prefer to work from that and hand-optimize it, all you need to do is remove the C source file from the project and add the .s file to it...then you can make edits freely and build the project using the assembly file instead.
