From 467c7c4c9665c0f8b41a4416722a027ebc05df2b Mon Sep 17 00:00:00 2001 From: Andreas Arnez <arnez@linux.ibm.com> Date: Mon, 21 Jan 2019 14:10:00 +0100 Subject: [PATCH] Bug 403552 s390x: Fix vector facility bit number The wrong bit number was used when checking for the vector facility. This can result in a fatal emulation error: "Encountered an instruction that requires the vector facility. That facility is not available on this host." In many cases the wrong facility bit was usually set as well, hence nothing bad happened. But when running Valgrind within a Qemu/KVM guest, the wrong bit was not (always?) set and the emulation error occurred. This fix simply corrects the vector facility bit number, changing it from 128 to 129. --- NEWS | 1 + VEX/pub/libvex_s390x_common.h | 2 +- 2 files changed, 2 insertions(+), 1 deletion(-) Index: valgrind-3.14.0/NEWS =================================================================== --- valgrind-3.14.0.orig/NEWS +++ valgrind-3.14.0/NEWS @@ -175,6 +175,7 @@ where XXXXXX is the bug number as listed 398028 Assertion `cfsi_fits` failing in simple C program 398066 s390x: cgijl dep1, 0 reports false unitialised values warning 402519 POWER 3.0 addex instruction incorrectly implemented +403552 s390x: wrong facility bit checked for vector facility n-i-bz Fix missing workq_ops operations (macOS) n-i-bz fix bug in strspn replacement Index: valgrind-3.14.0/VEX/pub/libvex_s390x_common.h =================================================================== --- valgrind-3.14.0.orig/VEX/pub/libvex_s390x_common.h +++ valgrind-3.14.0/VEX/pub/libvex_s390x_common.h @@ -103,7 +103,7 @@ #define S390_FAC_MSA5 57 // message-security-assist 5 #define S390_FAC_TREXE 73 // transactional execution #define S390_FAC_MSA4 77 // message-security-assist 4 -#define S390_FAC_VX 128 // vector facility +#define S390_FAC_VX 129 // vector facility /*--------------------------------------------------------------*/
