Bug ID: 460356
Summary: s390: Sqrt32Fx4 -- cannot reduce tree
Classification: Developer tools
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: ---
It has been seen that an application running under Valgrind on IBM Z Systems
crashes with this message:
Sqrt32Fx4(And32(Sub32(0x4:I32,t178),0x3:I32),LDbe:V128(t28))
vex: the `impossible' happened:
s390_isel_vec_expr: cannot reduce tree
...
Looking at the source, it seems that Sqrt32Fx4 is not implemented correctly.
