Subject: [PULL 03/24] tcg/i386: Move constraint type check to tcg_target_const_match
Date: Tue,  2 Feb 2021 16:15:29 -1000	[thread overview]
Message-ID: <20210203021550.375058-4-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210203021550.375058-1-richard.henderson@linaro.org>

Rather than check the type when filling in the constraint,
check it when matching the constant.  This removes the only
use of the type argument to target_parse_constraint.
