TITLE: OpenVMS VMS721_AMACRO-V0100 Alpha V7.2-1 AMACRO ECO Summary

New Kit Date: 06-JUN-2002
Modification Date: Not Applicable
Modification Type: NEW KIT
 
NOTE: An OpenVMS saveset or PCSI installation file is stored
       on the Internet in a self-expanding compressed file.
 
       For OpenVMS savesets, the name of the compressed saveset
       file will be kit_name.a-dcx_vaxexe for OpenVMS VAX or
       kit_name.a-dcx_axpexe for OpenVMS Alpha. Once the OpenVMS
       saveset is copied to your system, expand the compressed
       saveset by typing RUN kitname.dcx_vaxexe or kitname.dcx_alpexe.
 
       For PCSI files, once the PCSI file is copied to your system,
       rename the PCSI file to kitname.pcsi-dcx_axpexe or
       kitname.pcsi-dcx_vaxexe, then it can be expanded by typing
       RUN kitname.pcsi-dcx_axpexe or kitname.pcsi-dcx_vaxexe. The
       resultant file will be the PCSI installation file which can be
       used to install the ECO.

ECO KIT SUMMARY:

An ECO kit exists for OpenVMS Alpha V7.2-1. This kit addresses the
following problems:

PROBLEMS ADDRESSED IN VMS721_AMACRO-V0100 KIT:

  o The floating point support macros in AMAC_FLT$MACROS.MAR were
     recently rewritten. The floating point support macros do not
     handle VAX floating instructions that have "modify" operands
     (ie, ADDF2) that used auto-inc or auto-dec addressing modes.
     The ADDF2 macro uses the second operand twice in the generated
     code. This leads to the auto-inc or auto-dec being done twice
     instead of once.

          Images Affected: [SYSLIB]STARLET.MLB

  o An internal field to count flow nodes was limited to 32K.
     However, there was no check to see if it overflowed. When it
     overflowed, it caused an ACCVIO later downstream.

          Images Affected: [SYSEXE]ALPHA_MACRO.EXE

  o CMPW of values that are more than 32767 apart will give the
     wrong result.

          Images Affected: [SYSEXE]ALPHA_MACRO.EXE

  o AMACRO's floating point support macros do not correctly handle
     double-precision floating point immediate operands require
     more than 7 digits of precision.

          Images Affected: [SYSLIB]STARLET.MLB

INSTALLATION NOTES:

No reboot is necessary after successful installation of the kit.

INSTALLATION INSTRUCTIONS:

Install this kit with the POLYCENTER Software installation utility
by logging into the SYSTEM account, and typing the following at the
DCL prompt:

PRODUCT INSTALL VMS721_AMACRO /SOURCE=[location of Kit]

The kit location may be a tape drive, CD, or a disk directory that
contains the kit.

Additional help on installing PCSI kits can be found by typing
HELP PRODUCT INSTALL at the system prompt

SPECIAL INSTALLATION INSTRUCTIONS:

  o Scripting of Answers to Installation Questions

     During installation, this kit will ask and require user
     response to several questions. If you wish to automate the
     installation of this kit and avoid having to provide responses
     to these questions, you must create a DCL command procedure
     that includes the following definitions and commands:

        - $ DEFINE/SYS NO_ASK$BACKUP TRUE

        - Add the following qualifiers to the PRODUCT INSTALL
           command and add that command to the DCL procedure.

             /PROD=DEC/BASE=AXPVMS/VER=V1.0

        - De-assign the logicals assigned

     For example, a sample command file to install the
     VMS721_AMACRO-V0100 kit would be:

          $
          $ DEFINE/SYS NO_ASK$BACKUP TRUE
          $!
          $ PROD INSTALL VMS721_AMACRO/PROD=DEC/BASE=AXPVMS/VER=V1.0
          $!
          $ DEASSIGN/SYS NO_ASK$BACKUP
          $!
          $ exit
