3.22.10.11 struct x1f4_rdbl_type

typedef struct x1f4_rdbl_type {
    ...
    unsigned flags;
    const void *data, *miss;
} x1f4_rdbl_type;

The struct x1f4_rdbl_type record describes the parameters for the substitution of the (left operand) zero element combining operation optimization.

See Left Zero Element Promotion.

data

The data field is the address at which the value of the zero element is stored (the type of it is inferred from the operator description, it is the type of the left operand).

miss

The miss field is the address at which the value of the substituting element is stored (the type of it is inferred from the operator description, it is the type of the operator).

flags

The flags field is a bitwise OR of zero or more zero element promotion flag bits.
