Subject: [PATCH v2 00/11] Atomic cleanup + clang-12 build fix
Date: Fri, 16 Jul 2021 18:41:10 -0700 [thread overview]
Message-ID: <20210717014121.1784956-1-richard.henderson@linaro.org> (raw)
This is intended to fix building with clang-12 on i386.
Version 2 bears little relation to version 1, in that I no longer
turn off the warning, which merely hid the problem until link time
failed to find libatomic symbols.
In the process, I found bugs wrt handling of guest memory in target/
with respect to atomics, fixed by unifying the api between softmmu
and user-only and removing some ifdefs under target/.
Unification of the api allowed some further cleanups.
I think that patches 1-6 fix all of the bugs, and that 7-11 are only
cleanup and could be left to next cycle.
