'libgomp/testsuite/lib/libgomp.exp:libgomp_init' states: # For build-tree testing, also consider the library paths used for builing. # For installed testing, we assume all that to be provided in the sysroot. if { $blddir != "" } { [...] global hsa_runtime_lib if { $hsa_runtime_lib != "" } { append always_ld_library_path ":$hsa_runtime_lib" } } However, the libgomp GCN plugin is unconditionally built against the GCC-shipped 'include/hsa*.h' header files, and at run time does 'dlopen("libhsa-runtime64.so.1")', so there is no system-provided HSA Runtime library "used for builing". It thus doesn't make sense to amend 'LD_LIBRARY_PATH' for system-provided HSA Runtime library. libgomp/ * testsuite/lib/libgomp.exp (libgomp_init): Don't 'append always_ld_library_path ":$hsa_runtime_lib"'. * testsuite/libgomp-test-support.exp.in (hsa_runtime_lib): Don't set.
