constant / expression propagation

propagate

[default value: 2] Propagate constants ( 1=within each routine, 2=interprocedurally, 3=both, 0=no propagation).

prop_iterate

[default value: 2] Interprocedural expression propagation iteration ( 2=fixedpt, 1=double, 0=none).

prop_private

[default value: 0] Propagate private directives from BLOCK_BEGIN to enclosing loops.

pc_real

[default value: 0] 1 means propagate real expressions, 0 means do not.

pc_array

[default value: 1] 1 means propagate array expressions, 0 means do not.

pc_unreach

[default value: 1] 1 means delete unreachable code uncovered by constant propagation, 0 means do not.

pc_call_mods

[default value: 0] 1 means assume CALL stmts only modify their parameters when propagating constants, 0 means do not.

substitute

[default value: 1] 1 means substitute all propagated expressions, 0 means do not.

subst_parm

[default value: 1] 1 means substitute the values of PARAMETER statements into the program, 0 means do not.

sp_real

[default value: 0] 1 means substitute real parameters, 0 means do not.
