ECO KIT SUMMARY:

An ECO kit exists for AMACRO on OpenVMS Alpha V6.1 - V6.1-1H2.  This kit
addresses the following problems:

Problems addressed in the ALPAMAC03_061 kit:

  o  AMACRO is destroying one of the argument registers on a call when
     temporary registers are in short supply.


Problems addressed in the AXPAMAC02_061 kit:

  o  Routines for which the compiler can not find an exit point
     (e.g., absence of a RSB or a RSB that the compiler judges is
     unreachable) and that contain pushr or pushl instructions with
     registers as arguments would cause the compiler to bugcheck
     with a "Inconsistent register saves" message.

     The following macro code reproduces this problem:

        ;DKN1.MAR
        COMPILER_BUGCHECK::
                .JSB_ENTRY
                 pushl r10
                 calls #1,trace_out
        10$:    ; code...
                ; etc.
                BRB     10$
                RSB
        .END

        $ macro/migrate dkn1

                  pushl r10
        ^
        %AMAC-F-BUGCHK, compiler bugcheck, please report problem to
                        maintainers
        -MACRO-F-BUGTXT, Inconsistent register saves
        at line number 3 in file DSA201:[ACCOUNT_NAME]DKN1.MAR;1

  o  MACRO/MIGRATION (MACRO/MIGRATE) generates incorrect code (missing
     instructions) which causes the linked, executable, program to
     operate incorrectly.


Problems addressed in the AXPAMAC01_061 kit:

  o  AMACRO was generating incorrect code for an ADDW2 instruction when
     there was indirection in the operands.  This led to incorrect
     arithmetic results.

ECO KIT ORDERING INSTRUCTIONS:

If after an evaluation you wish to obtain this kit, request it
electronically using the appropriate Advanced Electronic Services
(AES) Service Tool.  If you are not familiar with how to request
kits electronically, open the DIA, WIS or DSNLINK database and
review the article entitled:

INSTALLATION NOTES:

In order for the corrections in this kit to take effect, the system
must be rebooted.  If the system is a member of a VMScluster, the entire
cluster should be rebooted in order to make use of the new image(s).
