OpenVMS ALPAMAC02_062 Alpha V6.2 AMACRO ECO Summary

 
NOTE:  An OpenVMS saveset or PCSI installation file is stored
       on the Internet in a self-expanding compressed file.
       The name of the compressed file will be kit_name-dcx_vaxexe
       for OpenVMS VAX or kit_name-dcx_axpexe for OpenVMS Alpha.
 
       Once the file is copied to your system, it can be expanded
       by typing RUN compressed_file.  The resultant file will
       be the OpenVMS saveset or PCSI installation file which
       can be used to install the ECO.

ECO KIT SUMMARY:

An ECO kit exists for ALPHA_MACRO.EXE on OpenVMS Alpha V6.2 - V6.2-1H2.
This kit addresses the following problems: 

Problems Addressed in the ALPAMAC02_062 Kit:

  o  Up-level reference not detected by MACRO-32 compiler, incorrect code
     is generated for the second CALLS to RDB$ATTACH_DATABASE 

     This is caused by a failure to correctly compile a transfer of
     control inside a program.  The most likely way to detect the problem
     is while stepping through a misbehaving program in the debugger, the
     program performs a JSR instruction (as the result of a compiled
     CALLS, for example) and doesn't jump to the subroutine that it
     should have, or access violates on performing the JSR.  What has
     happened is that R26 has been destroyed with an inappropriate
     address, but this is practically impossible to detect outside of a
     debugger.  Occasionally, images linked/traceback and a linker map
     will be enough to diagnose the condition. 

     This problem is corrected in OpenVMS Alpha V7.0.


Problems Addressed in the ALPAMAC01_062 Kit:

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


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.
