Hi all,
This patch adds a splitter variant of the minmax_arithsi pattern for when
the operator
is non-commutative (MINUS) and the ordering of the operands is not
canonical.
That is, it will trigger for:

Hi all,
This patch adds a splitter variant of the minmax_arithsi pattern for when
the operator
is non-commutative (MINUS) and the ordering of the operands is not
canonical.
That is, it will trigger for:
#define MAX(a, b) (a b ? a : b)
int
foo (int a, int b, int c)
{
return c - MAX (a,b);
}
