+; XFAIL: aix
+; AIX system assembler default print error for undefined reference .
+; so AIX chose to emit the available externally symbols into .s,
+; so that users won't run into errors in situations like:
+; clang -target powerpc-ibm-aix -xc -<<<$'extern inline __attribute__((__gnu_inline__)) void foo() {}\nvoid bar() { foo(); }' -O -Xclang -disable-llvm-passes
+
 ; test_function should not be emitted to the .s file.
