+# 3. ${CHOST}-clang wrappers are always installed for all ABIs included

+Subject: [PATCH 2/2] [test] Fix Cross-DSO CFI Android sanitizer test for
+ -rtlib=compiler-rt
+
+Fix the CHECK-CFI-CROSS-DSO-ANDROID test to be more precise and match
+specifically 'clang_rt.cfi' rather than any compiler-rt library. This
+fixes the failure when the linker command-line contains
+clang_rt.builtins library due to CLANG_DEFAULT_RTLIB=compiler-rt.
