Subject: [PATCH v2 08/10] target/openrisc: Remove 'TARGET_LONG_BITS != 32' dead code
Date: Thu,  9 Oct 2025 10:19:00 +0200	[thread overview]
Message-ID: <20251009081903.13426-9-philmd@linaro.org> (raw)
In-Reply-To: <20251009081903.13426-1-philmd@linaro.org>

The OpenRISC targets are only built as 32-bit:

  $ git grep TARGET_LONG_BITS configs/targets/or1k-*
  configs/targets/or1k-linux-user.mak:5:TARGET_LONG_BITS=32
  configs/targets/or1k-softmmu.mak:5:TARGET_LONG_BITS=32

Remove the dead code guarded within TARGET_LONG_BITS != 32.

Signed-off-by: Philippe Mathieu-Daudé <philmd@linaro.org>
