# 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.
