  • Closed as program error.

Error description

  • The following test case has two func() functions taking in
    different parameters defined in two different files func.c and
    foo.c.
    main.c uses the func() defined from func.c. foo.c's definition
    is not used.
    
    Using pdf1 and pdf2 to create pdf-optimized objects,
    with V9 and V10.1 compiler, compilation stops for compiling
    foo.c with error in the second pass.
    foo.c:
    1586-465 (S) Profiling data matching that from the pdf1 phase
    could not be found for function "func" in file "._pdf".
    Source files and/or compilation options may differ between the
    pdf1 and pdf2 phases.
    
    With V11.1 compiler
    compilation continues with warnings.
    
    main.c:
    1586-475 (W) New definition of function "main" is inconsistent
    with profiling data found in file "._pdf" from the pdf1 phase.
    Source files and/or compilation options may differ between the
    pdf1 and pdf2 phases. PDF Information will gnored for function
    "main".
    func.c:
    foo.c:
    1586-475 (W) New definition of function "func" is inconsistent
    with profiling data found in file "._pdf" from the pdf1 phase.
    Source files and/or compilation options may differ between the
    pdf1 and pdf2 phases. PDF Information will gnored for function
    "func".
