35# maybe_threads.cc was written to allow LD_PRELOAD=libtcmalloc.so to
36# work even on binaries that were not linked with pthreads.  This
37# unittest tests that, by running low_level_alloc_unittest with an
38# LD_PRELOAD.  (low_level_alloc_unittest was chosen because it doesn't
39# link in tcmalloc.)
40#
41# We assume all the .so files are in the same directory as both
42# addressmap_unittest and profiler1_unittest.  The reason we need
43# profiler1_unittest is because it's instrumented to show the directory
44# it's "really" in when run without any args.  In practice this will either
45# be BINDIR, or, when using libtool, BINDIR/.lib.
46
47# We expect BINDIR to be set in the environment.
48# If not, we set them to some reasonable values.
