Subject: [PATCH v2 01/27] include/exec: Introduce `CF_PCREL`
Date: Tue, 21 Feb 2023 23:17:52 +0100 [thread overview]
Message-ID: <20230221221818.9382-2-anjo@rev.ng> (raw)
In-Reply-To: <20230221221818.9382-1-anjo@rev.ng>
Adds a new field to TranslationBlock.cflags denoting whether or not the
instructions of a given translation block are pc-relative. This field
aims to replace the macro `TARGET_TB_PCREL`.
