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