V3.6 compiler enhancements

DB2 V9 support

  • Support for STDSQL(YES/NO)
  • Support for CREATE TRIGGER (aka multiple SQL statements)
  • Support for FETCH CONTINUE
  • Support for SQL style comments ('--') embedded in SQL statements
  • Support for Additional SQL TYPES including:
    • XML AS
    • BIGINT
    • BINARY
  • Listing the DB2 Coprocessor runtime options
  • Special handling of EXEC SQL DECLARE VARIABLE statements
  • Special handling of EXEC SQL xxx SQL TYPE IS xxx statements

Performance improvements

  • Extended-immediate instructions
    • The compiler now supports, under the ARCH(7) option, the extended-immediate facility in z/OS.
    • The extended-immediate facility provides 32-bit immediate-operand versions of the following instructions:
    • These instructions all allow the compiler to produce shorter and faster code sequences.
  • Extended-translation facility 2 instructions
    • The compiler that can now generate, under the ARCH(6) option, some of the instructions from the extended-translation facility 2 in z/OS. In particular, the compiler will generate the following instructions under ARCH(6) (or higher):
      • COMPARE LOGICAL LONG UNICODE (CLCLU) will be used to compare WIDECHAR expressions.
      • MOVE LOGICAL LONG UNICODE (MVCLU) will be used for assignments to WIDECHAR NONVARYING variables.
      • TEST DECIMAL (TP) will be used in code generated for the VALID built-in.
      • PACK ASCII (PKA) will be used in some conversions of PIC to FIXED DEC.
      • UNPACK ASCII (UNPKA) will be used in some conversions of FIXED DEC to PIC.
  • Ability to exploit CONVERT TO BINARY 64-BIT (CVBG) and CONVERT TO DECIMAL 64-BIT (CVDG) — Under ARCH(5), the compiler will use CVBG and CVDG to convert between FIXED BIN and FIXED DEC (and some PICTURE) when the precisions are too large for the conversion to be done with CONVERT TO BINARY 32-BIT (CVB) or CONVERT TO DECIMAL 32-BIT (CVD).
  • Expanded use of COMPARE LOGICAL LONG EXTENDED (CLCLE) — In V3.5, the CLCLE instruction was used in the code generated for some CHAR comparisons. Now, the CLCLE instruction will be used in the code generated for all CHAR comparisons except when the 2 lengths are known and equal, in which case better, special code has always been generated. CLCLE will now also be used for compares of GRAPHIC strings (except again when the 2 lengths are known and equal).
    • MVCLE will be used for assignments to CHAR NONVARYING when lengths are unknown.
    • MVCLE will be used for assignments to GRAPHIC NONVARYING when lengths are unknown.
  • Better code for packed decimal
    • Conversions from FIXED DEC(p,q) to FIXED DEC(r,s) will now be done entirely inline if r+q-s is greater than 31.
    • Conditional code is eliminated from assignments to PIC'(n)Z'.
    • In DO loops where the TO value is specified by a PICTURE variable, the code has been improved (by converting the PIC to FIXED DEC once before the loop begins).
    • Conversions with a drifting $ will now be inlined.
    • Conversions from FIXED BIN to a PICTURE that specifies a scale factor will now be inlined.
  • Conversions involving DB2 date-time patterns inlined
    • Conversions between dates using any of the three supported DB2 date-time patterns or the corresponding date-time patterns without any punctuation will now be done inline.
    • Code for REPATTERN will be inlined if the target date has a DB2 date-time pattern and the source has either a DB2 date-time pattern or a date-time pattern that starts with YYYYMMDD.
  • Miscellaneous
    • The assignment of ' ' to WIDECHAR is improved.
    • The ALLOCATION built-in function is now inlined.
    • Assignments to BIT variables that have inherited dimensions but which have strides that are divisible by eight will now be inlined.
  • Compiler performance
    • The compiler itself is compiled with ARCH(5).
    • The generation of the XREF listing has been significantly speeded up.

Usability enhancements

  • Additional and improved messages
    • Under CMPAT, notification is sent when an aggregate is too large.
    • When a KEYED DIRECT file without a KEY/KEYFROM clause is used, message IBM2180 will be issued.
    • In message IBM1435, the assumed precision will be 15.
    • The message flagging a semicolon in a comment will now include the line number of the line where the semicolon appears.
    • Assignments of FIXED DEC variables to FIXED DEC will be flagged if SIZE could be raised.
    • Message inserts are now passed to the compiler user exit.
    • IBM1387 will now indicate that the NODESCRIPTOR attribute will be ignored when it is invalid.
    • Assignments can change a REFER object will now be flagged (as they were under the old compiler with message IEL0653I).
  • ENV attribute in attributes listing — The ENV attribute if specified on the declare of a file will now be included in the attributes listing.
  • Control of CEESTART csect order — Under the new CEESTART option, the user can choose whether the compiler places the CEESTART csect at the beginning or the end of the generated object deck. Those users who want to use linker CHANGE cards must choose to have the compiler place CEESTART at the end of the object deck.
  • Flagged unused INCLUDE files — If the XREF option is in effect, then the compiler will issue a warning message for any INCLUDE file that contains no cross-referenced variables.
  • Ability to change the preprocessor default options — Via the new PPCICS, PPINCLUDE, PPMACRO and PPSQL options, the user may now change the default options for the corresponding preprocessor. In particular, using the PPSQL option, for example, in the IBMZIOP module would allow the user to specify the SQL preprocessor options that should be used whenever the PP(SQL) option is specified.
  • Ability to cast character to picture — With the new PICSPEC built-in function, the user can quickly cast CHARACTER data to PICTURE.
  • Enabled THREADID — The THREADID built-in function will now be enabled for z/OS.
  • NOREDUCE expanded — In an assignment of one structure to another, if the structures map, the assignment would normally be done as an aggregate move. But if the structure contained any POINTER fields, then the old compiler would have done the assignment field by field. Under the NOREDUCE option, the new compiler will also.
  • Listing allots more columns for line numbers — Previously, the Enterprise PL/I compiler allotted room for only five digits to hold the line number for the source in a compilation. With V3.6, the compiler will allot 7 columns to hold the line number.
  • More control over generated DEF files — The attribute DLLINTERNAL will be accepted in the OPTIONS attribute on PROCEDURE and ENTRY statements. This attribute will specify that the compiler should not put the named PROC or ENTRY in the generated DEF file.

Quality improvements: Extended conformance checking — Under the CHECK(CONFORMANCE) option, structures will now also be checked to see that they match.

Serviceability improvements

Automatic storage mapping — The MAP output has previously included a list in order of storage offset of the STATIC storage in the compilation. It will now also include a list in order of storage offset (per block) of the AUTOMATIC storage used by the block.

New/changed compiler options

  • ARCH — 7 is now accepted as a suboption. The default is now ARCH(5).
  • CEESTART — This new option controls where the compiler places the CEESTART csect in the generated object code. Under CEESTART(FIRST), the compiler places it at the beginning of the generated object code. Under CEESTART(LAST), the compiler places it at the end.
  • PPxx — The PPCICS, PPINCLUDE, PPMACRO, and PPSQL options are now accepted. Each of these allows the user to specify the options to be passed to the corresponding preprocessor.
  • REDUCE — Under NOREDUCE, the compiler will not reduce an assignment of matching structures to a simple move if the structures contain any POINTER fields.
  • TEST — The (NO)SEPNAME option is now supported. Under TEST(SEPARATE,NOSEPNAME), the name of the side file will not be placed in the object deck.
  • TUNE — 7 is now accepted as a suboption. The default is now TUNE(5).
