Thanks,
I managed to get an assembler output file, but it was just raw
assembler not "assembled". I'll try this out later today.

Yes. The gcc flag to get an assembly listing is -Wa,-a
so you could put that in your makefile, if you like. That causes gcc to
pass the option -a to the assembler.

The start of each function. If the C was compiled with the -g option,
source line numbers are - in fact the entire source is - available to
gdb or any other runtime debugger.
