You're right, no need to disassemble if the original assembly listing still exists somewhere. Any idea what it's named?
I've found the /Temp/build.../ directory where the code is compiled, but don't have anything that looks like assembly.
I have:
blink_1MHz.cpp <--- the original source code.
blink_1MHz.cpp.eep <--- just a single EOF record for the .hex file.
blink_1MHz.cpp.elf <--- Bunch of garbled text (Looks like it could be a raw hex file)
blink_1MHz.cpp.hex <--- .hex file as shown earlier.
blink_1MHz.cpp.o <--- object file
There's a few more .o files listed there, but I assume the object files aren't what I'm looking for. I was expecting to find a .s or a .lss file, but didn't see one.
