            Bug ID: 113778
           Summary: ICE: RTL check: expected elt 3 type 'e' or 'u', have
                    '0' (rtx code_label) in PATTERN, at rtl.h:1506 with
                    -march=armv9-a+sme -fhardened
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Keywords: ice-on-valid-code
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org

  Target Milestone: ---
              Host: x86_64-pc-linux-gnu
            Target: aarch64-unknown-linux-gnu

Created attachment 57333
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=57333&action=edit
reduced testcase (from gcc.target/aarch64/sme/sibcall_6.c)

This might need RTL checking enabled.

Compiler output:
$ aarch64-unknown-linux-gnu-gcc -march=armv9-a+sme -fhardened sibcall_6.i
during RTL pass: mode_sw
sibcall_6.i: In function 'shared_to_normal':
