Jiong Wang 3da8bcd0a0 bpf: enable sub-register code-gen for XADD ... Support sub-register code-gen for XADD is like supporting any other Load and Store patterns. No new instruction is introduced. lock *(u32 *)(r1 + 0) += w2 has exactly the same underlying insn as: lock *(u32 *)(r1 + 0) += r2 BPF_W width modifier has guaranteed they behave the same at runtime. This patch merely teaches BPF back-end that BPF_W width modifier could work GPR32 register class and that's all needed for sub-register code-gen support for XADD. test/CodeGen/BPF/xadd.ll updated to include sub-register code-gen tests. A new testcase test/CodeGen/BPF/xadd_legal.ll is added to make sure the legal case could pass on all code-gen modes. It could also test dead Def check on GPR32. If there is no proper handling like what has been done inside BPFMIChecking.cpp:hasLivingDefs, then this testcase will fail.
