Subject: [PATCH v2 00/15] target/ppc: Fix truncation of env->hflags
Date: Fri, 12 Mar 2021 19:00:03 -0600 [thread overview]
Message-ID: <20210313010018.819153-1-richard.henderson@linaro.org> (raw)
Version 2 is totally new.
Clean up everything that touches hflags, fixing quite a few
other bugs in the process.
* Do not put tcg internal state into migration, except to
retain backward compatibility.
* Do not touch anything in env in ppc_tr_init_disas_context.
* Do make sure that hflags contains everything that it should.
* Do verify that hflags is properly updated.
