Bug ID: 102072
Summary: New test case gcc.dg/vect/pr101145_3.c in r12-3136
fails on armeb
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: clyon at gcc dot gnu.org
Target Milestone: ---
The newly introduced test causes an ICE on armeb (arm big-endian, little-endian
is fine).
For instance --target armeb-none-linux-gnueabihf --with-cpu cortex-a9
--with-fpu neon-fp16:
FAIL: gcc.dg/vect/pr101145.c (internal compiler error)
FAIL: gcc.dg/vect/pr101145.c (test for excess errors)
Excess errors:
during GIMPLE pass: aprefetch
