Test case.

This is quite an increase of the code size for the attached test case.

sparc-rtems4.11-gcc (GCC) 4.9.4 20150723 (prerelease)
sparc-rtems4.12-gcc (GCC) 6.0.0 20160108 (experimental)
sparc-rtems4.11-gcc -c -O2 -o vprintk.4.11.o vprintk.i
sparc-rtems4.12-gcc -c -O2 -o vprintk.4.12.o vprintk.i
size vprintk.4.11.o
   text    data     bss     dec     hex filename
    688       0       0     688     2b0 vprintk.4.11.o
size vprintk.4.12.o
   text    data     bss     dec     hex filename
   1272       0       0    1272     4f8 vprintk.4.12.o

I noticed a size increase for various files, but this one was quite drastic.
