Bug ID: 97322
Summary: [11 regression] ICE in int_mode_for_mode, at
stor-layout.c:404 on arm
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: rtl-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: clyon at gcc dot gnu.org
Target Milestone: ---

preprocessed strtof_l.i
Since r11-3671 (g:bf510679bb3f9bfd6019666065016bb26a5b5466), I've noticed an
ICE while building the toolchains for arm. GCC crashes either while building
glibc or newlib.
I'm attaching a glibc reproducer: strtof_l.i
arm-none-linux-gnueabihf-gcc strtof_l.i -O2
during RTL pass: expand
In file included from strtof_l.c:45:
strtod_l.c: In function '____strtof_l_internal':
