Subject: [PATCH v2 00/29] tcg: Workaround macOS 11.2 mprotect bug
Date: Sun, 14 Mar 2021 15:26:55 -0600 [thread overview]
Message-ID: <20210314212724.1917075-1-richard.henderson@linaro.org> (raw)
Changes for v2:
* Move tcg_init_ctx someplace more private (patch 29)
* Round result of tb_size based on qemu_get_host_physmem (patch 26)
Blurb for v1:
It took a few more patches than imagined to unify the two
places in which we manipulate the tcg code_gen buffer, but
the result is surely cleaner.
There's a lot more that could be done to clean up this part
of tcg too. I tried to not get too side-tracked, but didn't
wholly succeed.
