[Fangrui Song via Phabricator via cfe-commits]

MaskRay added inline comments.


================
Comment at: clang/lib/CodeGen/CGDecl.cpp:1814
+    if (StopAfter) {
+      static unsigned Counter = 0;
+      if (Counter >= StopAfter)
----------------
I am a bit worried about the static variable. This makes CodeGen not reusable.


================
Comment at: clang/test/CodeGenCXX/auto-var-init-stop-after.cpp:1
+// RUN: %clang_cc1 -triple x86_64-unknown-unknown -fblocks -ftrivial-auto-var-init=pattern -ftrivial-auto-var-init-stop-after=2 %s -emit-llvm -o - | FileCheck %s -check-prefix=PATTERN-STOP-AFTER-2
+// RUN: %clang_cc1 -triple x86_64-unknown-unknown -fblocks -ftrivial-auto-var-init=pattern -ftrivial-auto-var-init-stop-after=3 %s -emit-llvm -o - | FileCheck %s -check-prefix=PATTERN-STOP-AFTER-3
----------------
You can drop `-fblocks`, because the test has nothing to do with the Blocks extension.
