The documentation seems to be saying that using those flags is
supposed to save flash, but without them, a main() that does a single
printf("foo\n"); gives me a 330 byte flash, while with them I get a
1330 byte flash.If I remove the printf() call, I get flash sizes of 1228 or 228 with or without the above mentioned printf-min flags, respectively. It looks like somehow the printf-min flag ends up dragging in a bunch extra code somehow? The rest of my linker invocation looks like this: avr-gcc -mmcu=atmega328p -lm -Wl,-gc-sections -Wl,-Map=program_to_upload.out.map -o program_to_upload.out main.o I think probably the documentation ought to mention this possibility, assuming it isn't a bug.
