Subject: [PATCH 21/29] tcg/ppc: Sink tcg_to_bc usage into tcg_out_bc
Date: Wed, 25 Oct 2023 00:26:59 -0700 [thread overview]
Message-ID: <20231025072707.833943-22-richard.henderson@linaro.org> (raw)
In-Reply-To: <20231025072707.833943-1-richard.henderson@linaro.org>
Rename the current tcg_out_bc function to tcg_out_bc_lab, and
create a new function that takes an integer displacement + link.
