   7 # Invoke it as "bash compare-all-tests target1 target2 ... targetN".
   8 # Assumptions are:
   9 #
  10 # 1) that the base and patched compilers reside respectively in
  11 # base-$target-build and $target-build, where $target is the commandline
  12 # argument to compare-all-tests, and should match the variables in the
  13 # script itself so that the correct set of options is tested.  Both
  14 # compilers should be fully built (including target libraries).
  15 #
  16 # 2) that the testsuite has been run on the base compiler (since it's
  17 # just compilation testing, using RUNTESTFLAGS=--target_board=basic-sim
  18 # usually suffices).
  19 #
  20 # Tests that fail to compile on the base compiler are not compared.
