Bug ID: 93236
Summary: [AArch64] ICE
Product: gcc
Version: 9.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: jimreesma at gmail dot com
Target Milestone: ---
On aarch64-linux-gnu,
ubuntu@ubuntu:~$ gcc -O -c gcc9_ice.c
during RTL pass: expand
gcc9_ice.c: In function ‘get’:
gcc9_ice.c:13:11: internal compiler error: in gen_rtx_SUBREG, at
emit-rtl.c:1010
13 | return u.s;
| ~^~
With the -O, or with -O0, no ice, and the emitted code works correctly.
