// This file tests the -Rpass family of flags (-Rpass, -Rpass-missed
// and -Rpass-analysis) with the inliner. The test is designed to
// always trigger the inliner, so it should be independent of the
// optimization level.
// RUN: %clang_cc1 %s -Rpass=inline -Rpass-analysis=inline -Rpass-missed=inline -O0 -emit-llvm-only -verify
// RUN: %clang_cc1 %s -DNDEBUG -Rpass=inline -emit-llvm-only -verify
// RUN: %clang_cc1 %s -Rpass=inline -emit-llvm -o - 2>/dev/null | FileCheck %s
// -Rpass should produce source location annotations, exclusively (just
// like -gmlt).
// CHECK: , !dbg !
// CHECK-NOT: DW_TAG_base_type
// But llvm.dbg.cu should be missing (to prevent writing debug info to
// the final output).
// CHECK-NOT: !llvm.dbg.cu = !{
