Subject: [PATCH 00/29] tcg: Introduce TCG_COND_TST{EQ,NE}
Date: Wed, 25 Oct 2023 00:26:38 -0700	[thread overview]
Message-ID: <20231025072707.833943-1-richard.henderson@linaro.org> (raw)

Inspired by some other patch review this week, expose a pair
of comparison operators that map to the "test" comparison
that is available on many architectures.

Convert target/alpha to use this as an exemplar.
