Bug ID: 103613
Summary: microblaze: ICE in reload pass when building PIE
Product: gcc
Version: 11.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: siddhesh at gcc dot gnu.org
Target Milestone: ---
This was found when running build-many-glibcs.py for microblazeel-linux-gnu
with this patch[1] (without the hunks that disable this for microblaze) to
build glibc programs as PIE. I'll post clearer steps to reproduce once the
glibc patch is pushed.
