Subject: [PATCH 08/43] tcg: Fix generation of dupi_vec for 32-bit host
Date: Tue, 8 Sep 2020 17:16:12 -0700 [thread overview]
Message-ID: <20200909001647.532249-9-richard.henderson@linaro.org> (raw)
In-Reply-To: <20200909001647.532249-1-richard.henderson@linaro.org>
The definition of INDEX_op_dupi_vec is that it operates on
units of tcg_target_ulong -- in this case 32 bits. It does
not work to use this for a uint64_t value that happens to be
small enough to fit in tcg_target_ulong.
