16# Simulate a setup, where two libraries provide the same import function;
17# %t.lib.dll.a is a pure import library which provides "libfunc".
18# %t.helper.a is a static library which contains "helper1" and "helper2".
19#
20# helper1 contains an undefined reference to libfunc. helper2 contains a
21# fake local implementation of libfunc, together with the __imp_libfunc
22# stub.
23#
24# %t.lib.dll.a is listed before %t.helper.a on the command line. After
25# including helper1, the library member that first declared the Lazy libfunc
26# (%t.lib.dll.a) gets enqueued to be loaded. Before that gets done, helper2
27# gets loaded, which also turns out to provide a definition of libfunc.
28# Once the import library member from %t.lib.dll.a gets loaded, libfunc
29# and __imp_libfunc already are defined.
