B.2.4 Inlining/IPA (INL)

• Routine "#1" analyzed interprocedurally. When optimizing the loop containing this call, IPA was performed on the called routine.

• Routine "#1" was inlined/IPAed. The call to this routine was replaced by the body of the routine to enhance optimization. The source of the subroutine or function is available either in the same file or in a specified library.

• Routine "#1" was not inlined/IPAed. Actual and formal parameter counts differ. The number of formal parameters in the definition of the program unit, in the same compilation stream or in the library, differs from the number of actual parameters at the call site.

• Routine "#1" was not inlined/IPAed. Space limitations exceeded. The inlining of subroutine or function calls at this statement was not attempted due to limitations placed on the amount of data structure space used in inline expansion.

• Routine "#2" was not inlined/IPAed. COMMON block "#1" item counts differ. The COMMON block mentioned is defined in both the program unit being called and the calling program unit. The number of separate entities in the two definitions do not match.

• Routine "#2" was not inlined/IPAed. COMMON block item "#1" has a shape mismatch. The COMMON block mentioned is defined in both the program unit being called and the calling program unit. The entity mentioned has a different shape (scalar or array) than its corresponding entity in the called program unit.

• Routine "#2" was not inlined/IPAed. COMMON block item "#1" has a type mismatch. The COMMON block mentioned is defined in both the program unit being called and the calling program unit. The entity mentioned has a different type (integer, logical, real, and so on) than its matching entity in the called program unit.

• Routine "#2" was not inlined/IPAed. External name "#1" has unresolvable conflict. In the called and calling routines, the definitions of an externally visible entity cannot be reconciled. This may be an error in the program itself.

• Routine "#2" was not inlined/IPAed. Non scalar parameter "#1" is passed into scalar. The actual parameter of a function/subroutine call differs in shape from the corresponding formal parameter, that is scalar.

• Routine "#2" was not inlined/IPAed. Parameter "#1" is a non-array passed into array. The actual parameter of a call statement differs in shape from the corresponding formal parameter, which is an array.

• Routine "#2" was not inlined/IPAed. Parameter "#1" cannot conform without linearizing. Before the program unit is placed inline, the translation of formal parameters to their actual equivalents must be made (a process called conformance). First the scalars in the parameter list are matched, then the arrays are examined to see what the proper translation is (the scalars are done first because bounds of an array parameter are often passed as a separate scalar). In this process, each dimension is compared, and a translation is constructed that tries to keep each dimension of the actual parameter separate. If this is not possible, the array references (or a portion of them) must be linearized to do the translation correctly. This is not desirable because the linearized subscripts violate the bounds of the array reference, and the data dependence tests used to optimize the program are compromised.

• Routine "#2" was not inlined/IPAed. Parameter "#1" has a class mismatch. Inline expansion or IPA was aborted due to class mismatch between formal and actual parameters.

• Routine "#2" was not inlined/IPAed. Parameter "#1" has type mismatch. For inlining to work, the types of the formal parameters and actual parameters must agree. Any program unit called with parameters of the wrong type will get an incorrect value unless assigned before any use in the call, and assigned before the next use after the call.

• Routine "#2" was not inlined/IPAed. Parameter "#1" whole array does not conform. Inline expansion or IPA was aborted because whole arrays do not conform.

• Routine "#2" was not inlined/IPAed. The shape of parameter "#1" is unknown. The shape of an actual parameter to a call cannot be determined. It must be array, scalar, or an intrinsic or external function call.
