            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

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:
