3.9.7.15 Variable Secondary To Constant Secondary Unary Transfer

The struct x1f4_1stscope_type operator definition extension is to include the X1f4_E4_NXAA_LIST bit in its bits1 bits list field. The remaining optimization parameters are to be introduced via the struct x1f4_operator_type first extension, in a struct x1f4_ndba_type definition. That is, the extension1 field of the struct x1f4_operator_type operator description must point a struct x1f4_1stscope_type record, whose ndba_data field must point a struct x1f4_ndba_type record, in turn describing the optimization parameters.

See struct x1f4_1stscope_type.

See struct x1f4_ndba_type.

See struct x1f4_operator_type.

See Operator First Extension Scope Flags.

The optimization transforms expressions like:

(c * -e) * (f * 2)

into:

(c * e) * (f * -2)
