APAR NUMBER: PJ41023 PRODUCT: z/TPF FUNCTIONAL AREA: DATA COLLECTION SHIPPED IN PUT: 10 ABSTRACT: PJ40865 incorrectly used a STG to save the initial stack frame address into the four byte field CE3CMSTK. PACKAGE CONTENTS: Source Segments: (C) base/cp/chsz.cpy Object Only Binaries: None. Configuration Independent Binaries: None. Support Files: None. OTHER BINARIES TO BUILD: YES (C) <sys>/obj/ccnucl.o (C) <sys>/load/CPS0.so COMMENTS: Prior to PJ40865, CE3CMSTK could contain garbage possibly leading to a CTL-4 or CTL-1 in data collection code. PJ40865 attempted to correct this problem by initializing CE3CMSTK to the initial stack frame address. However, a STG instruction was used to save the initial stack frame address into the four byte field CE3CMSTK. As a result, the CE3CMSTK field would be set to zero and the initial stack frame address saved into the first four bytes of the following reserved field CE3MRESVD. Even though PJ40865 was coded in error, it will prevent the possible CTL-4 and CTL-1 since it removes the possibility of CE3CMSTK having garbage in it.
SOLUTION: chsz.cpy was modified to use a ST instruction instead of a STG to save the initial stack frame address in CE3CMSTK. COREQS: NO None. MIGRATION CONSIDERATIONS: NO None. BUILD COMMANDS AND INSTRUCTIONS: YES #maketpf commands for linux maketpf -f CPS0 ccnucl.o maketpf CPS0 link UPDATED INFORMATION UNITS: NO None.
