            Bug ID: 115608
           Summary: ICE in extract_insn, at recog.cc:2812 when building
                    with -mv8plus
           Product: gcc
           Version: 14.1.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: glaubitz at physik dot fu-berlin.de
                CC: ebotcazou at gcc dot gnu.org, jrtc27 at jrtc27 dot com,

  Target Milestone: ---
            Target: sparc-linux-gnu

Support for the V8+ API seems to be broken in GCC as even trying to build a
simple program with "-mv8plus" fails:

(sid_sparc64-dchroot)glaubitz@stadler:~$ cat hello.c
#include <stdio.h>

int main () {
  printf("Hello World!");
  return 0;
}
(sid_sparc64-dchroot)glaubitz@stadler:~$ gcc-14 -mv8plus hello.c -o hello
hello.c: In function 'main':
hello.c:6:1: error: unrecognizable insn:

                ] UNSPEC_MOVE_PIC))) "hello.c":4:3 -1
     (nil))
