Subject: [PULL 02/24] tcg: Increase tcg_out_dupi_vec immediate to int64_t
Date: Wed, 13 Jan 2021 16:16:32 -1000 [thread overview]
Message-ID: <20210114021654.647242-3-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210114021654.647242-1-richard.henderson@linaro.org>
While we don't store more than tcg_target_long in TCGTemp,
we shouldn't be limited to that for code generation. We will
be able to use this for INDEX_op_dup2_vec with 2 constants.
Also pass along the minimal vece that may be said to apply
to the constant. This allows some simplification in the
various backends.
