Subject: [PATCH v4 02/30] target/arm: Rename TBFLAG_A32, SCTLR_B
Date: Fri, 16 Apr 2021 11:59:31 -0700
Message-ID: <20210416185959.1520974-3-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210416185959.1520974-1-richard.henderson@linaro.org>

We're about to rearrange the macro expansion surrounding tbflags,
and this field name will be expanded using the bit definition of
the same name, resulting in a token pasting error.

So SCTLR_B -> SCTLR__B in the 3 uses, and document it.
