Hi Tom,

I see the above failure for both aarch64-linux-gnu and arm-linux-gnueabihf in our testing.  The log shows ([1]):
===
Breakpoint 1, storage () at /home/tcwg-buildslave/workspace/tcwg_gnu_2/gdb/gdb/testsuite/gdb.ada/scalar_storage/storage.adb:53
53	   Do_Nothing (V_LE'Address);  --  START
(gdb) print V_LE
$1 = (value => 126, another_value => 12, color => green)
(gdb) PASS: gdb.ada/scalar_storage.exp: print V_LE
get_compiler_info: gcc-14-0-1
print V_BE
$2 = (value => 126, another_value => 12, color => red)
(gdb) FAIL: gdb.ada/scalar_storage.exp: print V_BE
===

Any idea what can be causing this?

This failure happens in CI configurations where we track tip-of-trunk GCC.

This failure is what I would expect if your compiler does not have the
fix.  Can you see if your gcc includes this change?

commit 5d8b60effc7268448a94fbbbad923ab6871252cd
Author: Eric Botcazou <ebotcazou@adacore.com>
Date:   Wed Jan 10 13:23:46 2024 +0100

    Fix debug info for enumeration types with reverse Scalar_Storage_Order
    
    This implements the support of DW_AT_endianity for enumeration types because
    they are scalar and therefore, reverse Scalar_Storage_Order is supported for
    them, but only when the -gstrict-dwarf switch is not passed because this is
    an extension.
    
    There is an associated GDB patch to be submitted to grok the new DWARF.

thanks,
Tom

Ah, now I understand.  While we do have the above commit in our GCC sources (we build tip-of-trunk in this CI configuration), we don't enable ada language.  So testsuite harness detects GCC version as 14.0 and enables the test, but actual gnat compiler is used from the distro package, which is much older.

We will consider enabling ada language in our CI builds, which should fix this.

Thanks for helping troubleshooting this!
