Bug ID: 34502
Summary: Regalloc assert fails: Unexpected VNI
Product: libraries
Version: 3.9
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Register Allocator
Assignee: unassignedb...@nondot.org

reduced testcase
This is actually a bug that may have kept the SystemZ build bots red for some
time now, but due to vacations this has not been reported yet. So this is quite
urgent.
I have done a git bisect, and found that it seems that commit 463fa38
(trunk@311401) is the cause for this.
The attached reduced test case fails with that commit, but compiles if it's
reverted.
