[PATCH] D78717: [SystemZ] Implement -fstack-clash-protection

[serge via Phabricator via llvm-commits]

serge-sans-paille added inline comments.


================
Comment at: llvm/lib/Target/SystemZ/SystemZFrameLowering.cpp:619
+
+  MachineInstr *StackAllocMI = nullptr;
+  for (MachineInstr &MI : PrologMBB)
----------------
could be:
```
auto Where = llvm::find_if(PrologMBB, [](MachineInstr& MI) { return MI.getOpcode() == SystemZ::STACKALLOC_W_PROBING;});
if(Where = PrologMBB.end()) return;
MachineInstr &StackAllocMI = *Where;
```
