I found a small regression caused by this, e.g.:
int g(void);
void f(int *p, int i)
{
p[i] = g();
p[i + 2] = g();
p[i + 1] = g();
p[i + 100] = g();
}
If I compile it with -fdump-tree-original I get this in the dump:
*(p + (unsigned int) ((unsigned int) i * 4)) = g ();
*(p + ((unsigned int) ((unsigned int) i * 4) + 8)) = g ();
*(p + ((unsigned int) i + 1) * 4) = g ();
*(p + ((unsigned int) ((unsigned int) i * 4) + 400)) = g ();
Notice that it generates the (i + 1) * 4 instead of (i * 4) + 4 as with
the other cases. While I tried to debug this I narrowed it down to the
changes in fold_binary(), but I don't really know how to fix this, so
I could use some help here.
Thanks.
