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