This test exercises GDB's internal TLS support when both the main program and several shared libraries have TLS variables. It also tests existing (non-internal) TLS support too. It tests using two compilation scenarios, "default", in which libpthread is not linked with the program and libraries as well as one which does use libpthread. It tests link map address to module id mapping code in GDB in addition to the ability of GDB to traverse TLS data structures with several libraries in play.
