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