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. Copyright (c) Digital Equipment Corporation 1996. All rights reserved. PRODUCT: OpenVMS Alpha COMPONENT: ALPHA_MACRO.EXE - AMACRO SOURCE: Digital Equipment Corporation ECO INFORMATION: ECO Kit Name: ALPAMAC02_062 ECO Kits Superseded by This ECO Kit: ALPAMAC01_062 ECO Kit Approximate Size: 10755 Blocks Kit Applies To: OpenVMS Alpha V6.2, V6.2-1H1, V6.2-1H2, V6.2-1H3 System/Cluster Reboot Necessary: Yes 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.
