In my opinion, the better fix would be something like:
typedef int SImode __attribute__((mode(SI)));
typedef int DImode __attribute__((mode(DI)));
Then:
SImode
foosi (SImode x)
{
...
}
DImode
foodi (DImode x)
{
...
}
As these patterns are explictly testing that the back-end patterns are
triggered for data of any type, under any ABI, with the appropriate mode.
