Bug ID: 444242
Summary: s390x: Valgrind crashes on EXRL with negative offset
Product: valgrind
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: vex
Assignee: jsew...@acm.org
Reporter: ar...@linux.ibm.com
Target Milestone: ---
Valgrind's implementation of the "execute relative long" (EXRL) instruction
zero-extends the offset instead of sign-extending it. This has been seen to
cause a crash with SIGSEGV in s390_irgen_EXRL() when a negative offset
occurred.
