            Bug ID: 31574
           Summary: [gdb, armv8l] FAIL: gdb.ada/verylong.exp: print x
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ada

  Target Milestone: ---

In an armhf container on an aarch64-linux host, I run into:
...
PASS: gdb.ada/verylong.exp: compilation prog.adb
FAIL: gdb.ada/verylong.exp: print x
FAIL: gdb.ada/verylong.exp: print x / 2
FAIL: gdb.ada/verylong.exp: print (x / 4) * 2
PASS: gdb.ada/verylong.exp: print x - x
FAIL: gdb.ada/verylong.exp: print x - 99 + 1
FAIL: gdb.ada/verylong.exp: print -x
FAIL: gdb.ada/verylong.exp: print +x
PASS: gdb.ada/verylong.exp: print 170141183460469231731687303715884105727
FAIL: gdb.ada/verylong.exp: print x =3D 17014118346046923173168730371588410=
5727
...

In more detail:
...
(gdb) print x^M
$1 =3D 9223372036854775807^M
(gdb) FAIL: gdb.ada/verylong.exp: print x
...

A passing version on x86_64-linux looks like:
...
(gdb) print x^M
$1 =3D 170141183460469231731687303715884105727^M
(gdb) PASS: gdb.ada/verylong.exp: print x
