Description Andrew Pinski 2004-11-12 03:53:15 UTC 
From PR 18404 (but that was about something else)
Do:
gcc.mips -S -O2 -march=sb1 -mabi=64 -mint64 t.c
on t.c:
typedef signed char t_SI __attribute__ ((__mode__(SI)));
t_SI inc_SI (t_SI v) {
    return ++v;
}

This came about with the scalar_mode_supported_p work. Patch in testing.
