Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of IBM Automatic Binary Optimizer      *
  *                 (ABO) for z/OS, v2.1                         *
  ****************************************************************
  * PROBLEM DESCRIPTION: This APAR addresses the following       *
  *                      issues from the ABO 2.1 PTF:            *
  *                                                              *
  *                      1) For some modules that contain a      *
  *                      large number of PERFORM statements,     *
  *                      ABO may consume high amounts of CPU     *
  *                      time and memory. ABO was modified to    *
  *                      reduce memory usage and CPU time        *
  *                      consumption for some modules            *
  *                      containing these statements.            *
  *                                                              *
  *                      2) This APAR improves the RTI Profiler  *
  *                      output by providing a 'Summary Report   *
  *                      by Language' section. The following     *
  *                      information is displayed for each       *
  *                      language:                               *
  *                      - Number of samples collected from the  *
  *                      application, displayed as an absolute   *
  *                      number as well as a percentage of       *
  *                      total samples from the run              *
  *                      - Number of samples collected from any  *
  *                      COBOL specific LE routines, displayed   *
  *                      as an absolute number and as a          *
  *                      percentage of total samples from the    *
  *                      run                                     *
  *                                                              *
  *                      3) This new function APAR enhances the  *
  *                      listings of ABO optimized modules by    *
  *                      displaying additional data from the     *
  *                      prolog sections of each CSECT           *
  *                      including the program prolog areas      *
  *                      PPA1 and PPA2. This additional data is  *
  *                      displayed for CSECTs compiled by        *
  *                      compiler releases from COBOL/370 1.1    *
  *                      to Enterprise COBOL V4R2. CSECTs        *
  *                      compiled by VS COBOL II 1.3 and 1.4 do  *
  *                      not display this additional data.       *
  *                                                              *
  *                      4) In some rare situations, when        *
  *                      optimizing input modules containing     *
  *                      PERFORM statements, ABO may issue       *
  *                      'BOZ1455W Unsupported feature "Program  *
  *                      Complexity 182" found' message and      *
  *                      skip optimization of the CSECT. ABO     *
  *                      was modified to successfully optimize   *
  *                      some input modules which contain these  *
  *                      statements.                             *
