3.9.7.11 Resolving Constant Secondary Constant Direct Secondary Terms

The struct x1f4_1stscope_type operator definition extension is to include the X1f4_E4_MXAS_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_odbs_type definition. That is, the extension1 field of the struct x1f4_operator_type operator description must point a struct x1f4_1stscope_type record, whose odbs_data field must point a struct x1f4_odbs_type record, in turn describing the optimization parameters.

See struct x1f4_1stscope_type.

See struct x1f4_odbs_type.

See struct x1f4_operator_type.

See Operator First Extension Scope Flags.

The optimization transforms expressions like:

e << 2 << 2
e << 2 << c << 2

into:

e << 4
e << 4 << c
