Subject: [PATCH v3 03/14] tcg/arm: Simplify use_armvt5_instructions
Date: Wed, 18 Aug 2021 11:29:01 -1000	[thread overview]
Message-ID: <20210818212912.396794-4-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210818212912.396794-1-richard.henderson@linaro.org>

According to the Arm ARM DDI 0406C, section A1.3, the valid variants
are ARMv5T, ARMv5TE, ARMv5TEJ -- there is no ARMv5 without Thumb.
Therefore simplify the test from preprocessor ifdefs to base
architecture revision.  Retain the "t" in the name to minimize churn.
