Bug ID: 99648
Summary: [11 regression] gcc.dg/torture/pr71522.c fails
starting with r11-165 for 32 bits
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: other
Assignee: unassigned at gcc dot gnu.org
Reporter: seurer at gcc dot gnu.org
Target Milestone: ---

This works fine for 64 bits and worked fine for BE 32 bits for r11-164 and
earlier.
