Subject: [PATCH v2 0/4] linux/sparc: more get/set_context fixes
Date: Fri, 6 Nov 2020 15:27:34 +0000 [thread overview]
Message-ID: <20201106152738.26026-1-peter.maydell@linaro.org> (raw)
Based-on: 20201105212314.9628-1-peter.maydell@linaro.org
("[PATCH for-5.2 0/3] linux-user: fix various sparc64 guest bugs")
This series fixes a few more issues with our sparc linux-user
sparc64_get_context() and sparc64_set_context() implementation:
* we weren't handling FPU regs correctly, and also the way
we coded the handling triggered Coverity warnings
* some stray pointless error checks
* we shouldn't restore %g7 in set_context
* we weren't saving and restoring tstate correctly
My main aim here was to deal with the Coverity errors, but
the rest are things I noticed while I was working on the
code or which had fixme comments, and I figured I'd fix
them while the code was fresh in my mind.
thanks
