[PATCH] D137905: [GlobalISel] Add new G_INVOKE_REGION_START/END instructions to fix an EH bug

[Jessica Paquette via Phabricator via llvm-commits]

paquette added a comment.

Does `G_INVOKE_REGION_START` work with the `terminators()` iterator?



================
Comment at: llvm/lib/CodeGen/MachineBasicBlock.cpp:258
+MachineBasicBlock::iterator MachineBasicBlock::getFirstTerminatorForward() {
+  iterator I = begin(), E = end();
+  while (I != E && !I->isTerminator())
----------------

Should we check for debug instructions + skip them here like in `getFirstTerminator()`, or is that not necessary?
