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 -- PMM Peter Maydell (4): linux-user/sparc: Correct sparc64_get/set_context() FPU handling linux-user/sparc: Remove unneeded checks of 'err' from sparc64_get_context() linux-user/sparc: Don't restore %g7 in sparc64_set_context() linux-user/sparc: Handle tstate in sparc64_get/set_context() target/sparc/cpu.h | 28 +++++++++--- linux-user/sparc/signal.c | 87 ++++++++++++++++++++----------------- target/sparc/int64_helper.c | 5 +-- 3 files changed, 71 insertions(+), 49 deletions(-) -- 2.20.1
