[avr-libc-dev] [bug #50811] using -Wl, -u, vfprintf -lprintf_min causes program to grow a lot

[Georg-Johann Lay]

Follow-up Comment #9, bug #50811 (project avr-libc):

Re. the "compiler thing" mentioned above:

avr-gcc might replace a call to printf by a call to puts provided the
arguments of printf allows to do so.  You can avoid this optimization by means
of -fno-builtin-printf which takes away any knowledge (except prototype
information) about printf from the compiler.  This will result in a call to
printf (which you are using anyway), saving the call to fputs.
