Subject: [PATCH v4 00/17] target/ppc: Fix truncation of env->hflags
Date: Mon, 15 Mar 2021 12:45:58 -0600	[thread overview]
Message-ID: <20210315184615.1985590-1-richard.henderson@linaro.org> (raw)

Changes for v4:
 * Use hregs_recompute_hflags for hw/ppc/ reset.
   -- Incorporate Cedric's feedback.

Changes for v3:
 * Fixes for linux-user, signal handling and startup.
   -- Oops, the directory in which I did testing for v2
      had a reduced set of targets.

Changes for v2:
 * 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.
