[Qemu-devel] [PATCH v8 00/37] cmpxchg atomic operations |
Date: |
Mon, 24 Oct 2016 10:39:11 -0700 |
Changes v7-v8:
* Atomics fix for gcc 4.2 (centos6)
* All atomic.h changes split out from 'tcg: Add atomic helpers',
as requested by ... someone (Emilio?)
* Unused function reported by clang for
'target-arm: emulate LL/SC using cmpxchg helpers'
If this meets with everyone's satisfaction, I'll send another
cover-letter with another pull request.
