[llvm-dev] [PPC64] mflr gets scheduled after __tls_get_addr call
Hi, I got a minimized test case that's causing miscompiled TLS initialization code: https://gist.github.com/innocentim/939ebbff1e312801bafe Should I just insert PPC::STACKCALLDOWN AND PPC::STACKCALLUP into ppc-tls-dynamic-call? I'm not quite sure if the frame size is simply 0? Thanks! -------------- next part -------------- An HTML attachment was scrubbed...

You should probably open a bug report.
