sfmode.c: C test case
There is currently the problem that subreg lowering is producing code that
later passes cannot really digest:
With avr-gcc v14.1:
$ avr-gcc sfmode.c -Os -c -mmcu=atmega8 -dp -save-temps -dumpbase "" &&
avr-size sfmode.o
text data bss dec hex filename
160 0 0 160 a0 sfmode.o
whereas with v8:
text data bss dec hex filename
40 0 0 40 28 sfmode.o
