+// This is a regression test for ThinLTO indirect-call-promotion when candidate
+// callees need to be imported from another IR module. In the C++ test case,
+// `main` calls `global_func` which is defined in another module. `global_func`
+// has two indirect callees, one has external linkage and one has local linkage.
+// All three functions should be imported into the IR module of main.
+
+// What the test does:
+// - Generate raw profiles from executables and convert it to indexed profiles.
+// During the conversion, a profiled callee address in raw profiles will be
+// converted to function hash in indexed profiles.
+// - Run IRPGO profile use and ThinTLO prelink pipeline and get LLVM bitcodes
+// for both cpp files in the C++ test case.
+// - Generate ThinLTO summary file with LLVM bitcodes, and run `function-import` pass.
+// - Run `pgo-icall-prom` pass for the IR module which needs to import callees.
+
+// Use lld as linker for more robust test. We need to REQUIRE LLVMgold.so for
+// LTO if default linker is GNU ld or gold anyway.
+// REQUIRES: lld-available
+
+// Test should fail where linkage-name and mangled-name diverges, see issue https://github.com/llvm/llvm-project/issues/74565).
+// Currently, this name divergence happens on Mach-O object file format, or on
+// many (but not all) 32-bit Windows systems.
+//
+// XFAIL: system-darwin
+//
+// Mark 32-bit Windows as UNSUPPORTED for now as opposed to XFAIL. This test
+// should fail on many (but not all) 32-bit Windows systems and succeed on the
+// rest. The flexibility in triple string parsing makes it tricky to capture
+// both sets accurately. i[3-9]86 specifies arch as Triple::ArchType::x86, (win32|windows)
+// specifies OS as Triple::OS::Win32
+//
+// UNSUPPORTED: target={{i.86.*windows.*}}
