Dynamic linking on PPC64 has had problems since we had to move the top-down hazard-detection logic post-ra. For dynamic linking to work there needs to be a nop placed after every call. It turns out that it is really hard to guarantee that nothing will be placed in between the call (bl) and the nop during post-ra scheduling. Previous attempts at fixing this by placing logic inside the hazard detector only partially worked. This is now fixed in a different way: call+nop codegen-only instructions. As far as CodeGen is concerned the pair is now a single instruction and cannot be split. This solution works much better than previous attempts. The scoreboard hazard detector is also renamed to be more generic, there is currently no cpu-specific logic in it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153816 91177308-0d34-0410-b5e6-96231b3b80d8 |
