All -

I'm using a model-based design environment which auto-generates C code. In this environment, there's a multitude of code-generation settings which can drastically change the look and architecture of the generated code.

I'm trying to come up with a quick way to objectively compare code generation settings in terms of memory usage without actually running the code. The generated code does not use dynamic memory allocation, so all of the memory used is statically allocated, and I think the linker should be able to tell me how much static memory is used.

I've been able to generate a .map file from the linker (I'm using MS Visual Studio 2005), but having trouble understanding it. I haven't been able to find any documentation on the format of the map file. I've included the first 30 or so lines below, which I think contains information about memory segments of local variables among other things. Can someone help me decipher this?

Thanks!
