[PATCH] D136169: [AMDGPU] Avoid SCC clobbering before S_CSELECT_B32

[Sebastian Neubauer via Phabricator via llvm-commits]

sebastian-ne added inline comments.


================
Comment at: llvm/lib/Target/AMDGPU/SIRegisterInfo.cpp:2238
+              .addReg(FrameReg)
+              .addImm(Offset);
+          BuildMI(*MBB, MI, DL, TII->get(AMDGPU::S_BITCMP1_B32))
----------------
Maybe it makes sense to add an assert, that the least significant bit of `Offset` is indeed 0? (here and for s_subb below)
