Description

Performance improvements

  • Additional exploitation of the hardware is implemented in the compiler to improve performance of the generated code:
    • CU12, CU14, CU21, CU24, CU41, and CU42 system instructions are used to give you faster Unicode conversions. For example CU12, convert from UTF-8 to UTF-16
    • TRTT, TROT, TRTO, and TROO system instructions are now used to give you faster Unicode translations. For example TRTT, translate two bytes to two bytes (can be used to case one UTF-16 string into another UTF-16 string)
    • The compare-and-trap hardware instruction is used for faster tests for dereferencing of null pointers.
  • The ARCH option controls the code generated by adjusting the instructions, scheduling, and other optimizations for a specific architecture level of the system. The PL/I compiler, itself is now built with the higher level ARCH(6) resulting in improved compilation performance
  • Miscellaneous improvements to generated code
    • Improved code generated for UVALID
    • Improved code generated for some array assignments
    • Directly inline ROUND for Decimal Floating Point (DFP) instead of using a slower library call
    • Improved BIN(31, 31) compares

Usability enhancements

  • Block-scoping in the CICS and SQL preprocessors is now supported.
  • You can include Decimal Floating Point (DFP) in restricted expressions when using math built-in functions.
  • Support for UTF-8 and UTF-16 is improved:
    • New built-in functions support faster conversions amongst UTF-8, UTF-16 and UTF-32.
    • New built-in functions support faster translations amongst UTF-8 and UTF-16.
    • A new built-in function supports the testing of a UTF string for the presence of surrogate characters.
    • UVALID is inlined for small strings
  • The following date patterns with blank suppression are supported:
    • ZY-ZM-ZD
    • ZM/ZD/ZY
    • ZD.ZM.ZY
    • YY-ZM-ZD
    • ZM/ZD/YY
    • ZD.ZM.YY
  • Support for INONLY, INOUT, and OUTONLY attributes is enabled to improve the documentation of function prototypes and the flagging of uninitialized variables.
  • You can now control whether sysnull or null is assigned to a pointer when the source in the assignment is a null string.
  • The MACRO preprocessor leaves %include, %xinclude, %inscan, and %xinscan in the compiler listing as comments making it easier for you to locate that code in the listings.
  • An additional MACRO construct, %DO SKIP, makes it possible to support meta-comments.
  • You can specify that a DFP number should be rounded at the nth decimal digit (rather than at the nth digit as provided by the ROUND built-in function in accordance with the ANSI definition).
  • For ease of use and reduced confusion for many PL/I programmers the flagging of apparently unused %INCLUDE is now dropped.
  • A new compiler option suppresses PUT FILE and/or DISPLAY statements. PL/I programmers can now use these statements for debug purposes while more easily compiling them out of the production version.

Quality improvements

  • The compiler now flags code where the result of a FIXED operation has a scale factor less than zero.
  • The compiler now flags ENTRYs used as functions but declared without the RETURNS attribute.
  • The compiler now flags with a new, unique message the use of a duplicate ORDINAL in a SELECT statement.
  • The new ONSNAP option allows you to request the compiler to insert an ON STRINGRANGE SNAP statement or an ON STRINGSIZE SNAP statement into the prologue of a MAIN or FromAlien procedure so that the calling module and module name can be identified.
  • You can optionally have the compiler flag declares of FIXED DEC(p,q) and FIXED BIN(p,q) where q is less than 0 or q is greater than p.
  • The compiler now flags parameters declared inappropriately as BYVALUE, for example, declaring a FIXED DEC parameter BYVALUE.
  • An option flags statements generating lots of code. With this option, programmers have the knowledge to help them improve the efficiency of their programming.
  • A new option forces macro procedures and variable names to start with a specified character. This option allows you to enforce quality and naming standards for your organization.
  • An option checks if null pointers are dereferenced.
  • The RULES suboption is enhanced to help identify areas where coding can be improved:
    • NOPROCENDONLY is added to flag END statements for PROCs that do not name the PROC they are closing.
    • NOSTOP is added to flag the use of STOP and EXIT.
    • NOLAXQUAL(STRICT) is added to flag references to variables not qualified with their level-1 name.
    • NOGOTO(LOOSE) is added to allow GOTOs only if in the same block.
  • The following changes are made to the compiler options for simplification:
    • The COMPACT option is dropped.
    • The default setting for DEFAULT(REORDER/ORDER) is changed to DEFAULT(REORDER).
    • The TUNE option is dropped.

Serviceability improvements

  • When the compiler cannot open a file, the compiler will now, if possible, also include the related C runtime message in the message in the listing.
  • If user code requires a DFP conversion at compile time but the compile is running on a machine without DFP hardware, this error will be trapped and a meaningful error issued.
  • If the SQL preprocessor is invoked more than once without INCONLY as its suboption, then the DBRM library created by the compiler will be empty, and now an E-level message will be issued to warn the user.
