I am not 100% sure about how GNU compiler and assembler handle things, but in general, if you don't mind using global variables, then you can declare them in your C environment and reference them in your assembly code. This will allow you to access these global variables from both worlds. Alternatively, if you are going to use local variables instead of global ones, you can call your assembly routine from your C code and pass the local variables through the function arguments. If you pass the variables by reference, you should be able to modify their values as well which would allow you to copy the values of your labels in the assembly world into these arguments and pass them back to the C world. Lastly, if you are planning to use inline assembly, I am afraid I am not too sure what you can and can't do. You might be able to just put the name of the variable with an underscore in front of it in your inline assembly code and access it that way. Hope this helps a little.
