[PATCH] D121327: Lower `@llvm.global_dtors` using `__cxa_atexit` on MachO

[Julian Lettner via Phabricator via llvm-commits]

yln added inline comments.


================
Comment at: llvm/lib/CodeGen/TargetPassConfig.cpp:898-902
+  // For MachO, lower .llvm.global_dtors into .llvm_global_ctors with
+  // __cxa_atexit calls to avoid emitting the deprecated __mod_term_func.
+  if (TM->getTargetTriple().isOSBinFormatMachO())
+    addPass(createLowerGlobalDtorsLegacyPass());
+
----------------
Is `TargetPassConfig::addIRPasses()` the right place to hook this pass?
