3.9.7.9 Resolving Constant Secondary Constant Primary Terms

The struct x1f4_1stscope_type operator definition extension is to include the X1f4_E4_MXAC_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_odbc_type definition. That is, the extension1 field of the struct x1f4_operator_type operator description must point a struct x1f4_1stscope_type record, whose odbc_data field must point a struct x1f4_odbc_type record, in turn describing the optimization parameters.

See struct x1f4_1stscope_type.

See struct x1f4_odbc_type.

See struct x1f4_operator_type.

See Operator First Extension Scope Flags.

The optimization transforms expressions like:

(e + 2) + (2 + c)

into:

e + 4 + c
