Summary: [10 regression][arm] gcc.dg/pr83930.c ICE since
r274986
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org

After r274986, even with the patch from
https://gcc.gnu.org/ml/gcc-patches/2019-08/msg02018.html, I've noticed:
FAIL: gcc.dg/pr83930.c (internal compiler error)
--target arm-none-linux-gnueabi
--with-mode thumb
--with-cpu cortex-a9
with Dejagnu RUNTESTFLAGS: -march=armv5t
during RTL pass: expand
