 # REQUIRES: x86
+## This tests that lld handles (re)exported libraries with rpath properly .
+## The tests are as follows:
+## - libAee re-exports libBee while defining the install-path with @rpath variable
+##   - libBee re-exports libCee while defining the install-path with @rpath variable
+##     - libCee contains _c_func symbol.
+##
+## We check that when linking a main which references _c_func, lld can find the symbol.
