Subject: [PATCH v9 00/24] target/arm: Reduce overhead of cpu_get_tb_cpu_state
Date: Wed, 23 Oct 2019 11:00:33 -0400 [thread overview]
Message-ID: <20191023150057.25731-1-richard.henderson@linaro.org> (raw)
Changes since v8:
* Rebuild hflags in linux-user/*/cpu_loop.c, after changing to big-endian.
This allows the armeb busybox ls to pass. I don't have a test image for
aarch64_eb, but the code looks the same.
Changes since v7:
* Rebuild hflags for all successful nvic writes (Peter).
* Rebuild hflags for Xscale sctlr writes (Peter).
Changes since v6:
* Regen hflags in two more places for m-profile (patch 19).
