Subject: [PATCH v2 09/10] target/openrisc: Inline tcg_gen_trunc_i64_tl()
Date: Thu,  9 Oct 2025 10:19:01 +0200	[thread overview]
Message-ID: <20251009081903.13426-10-philmd@linaro.org> (raw)
In-Reply-To: <20251009081903.13426-1-philmd@linaro.org>

The OpenRISC targets are only built as 32-bit, so tcg_gen_trunc_i64_tl
expands to tcg_gen_extrl_i64_i32(). Use the latter to simplify the
next commit mechanical change.
