; This test has no module flag {"tls-load-hoist", i32 0}, so use --tls-load-hoist=x
; to choose the way of loading thread_local address.

; This test come from compiling clang/test/CodeGen/intel/tls_loads.cpp with:
; (clang tls_loads.cpp -fPIC -ftls-model=global-dynamic -O2 -S -emit-llvm)

; For HOIST0, check call __tls_get_addr@PLT only one time for each thread_local variable.
