+# This namespace provides some convenience functions for running

+#
+# Exported functions are defined inline below.
+#
+# General usage:
+#
+# Start a new session, noting that the variable "var" will be used for
+# "compile code" expressions. This variable /must/ exist in the stopped
+# location.
+#
+# CompileExpression::new "var"
+#
+# Test the implicit expression "foo;" with result/value 3.
+# CompileExpression::test "foo" 3
+# ---> Runs the following tests (name of tests ignored for illustration)
+# gdb_test_no_output "compile code var = foo"
+# gdb_test "p var" "= 3"
+# gdb_test "compile print foo;" "= 3"
+#
+# Test the explicit expression "a = function (3); var = a;" with the result 21.
+# CompileExpression::test "a = function (3); var = a;" 21 -explicit
+# ---> Runs the following tests (name of tests ignored for illustration)
+# gdb_test_no_output "compile code a = function (3); var = a;"
+# gdb_test "p var" "= 21"
+#
+# Additional option flags may be passed to test to control the behavior
+# of the test harness:
+#
+# Pass -explicit to specify that the test uses an explicit expression,
+# one which sets the value of the variable (see above). Only the code test
+# will be run.
+#
+# Pass -value and/or -print to indicate that the value and/or print steps
+# will optionally fail. Specify "xfail" or "kfail" to indicate how
+# particular step will fail. These may be followed by any accepted DejaGNU
+# parameters such as architecture and bug#. [See examples below.]
+#
+# To specify that the compile (and consequently print and value tests) is
+# expected to kfail/xfail, use -kfail or -xfail with any appropriate
+# DejaGNU parameters. Both options override -print and -value.
+# [-xfail is given precedence over -kfail should both be given.]
+#
+# -value is used when a "code" test is run, specifying that the "compile
+# code" and "print VAR" steps will fail in the prescribed manner.
+# [If the print step generates a PASS, the test is considered invalidly
+# written. VAR's value should /always/ be invalidated before a test is
+# run.]
+#
+# -print is used to specify that an expression will fail in the prescribed
+# manner when "print" test is executed.
+#
+# Pass "-name NAME" to set an optional test name. If not specified,
+# the harness will use test names such as "compile code EXPR" and
+# "result of compile code EXPR".
+#
+# Pass "-noprint" or "-nocode" to suppress print or code tests, respectively,
+# This is useful when the expression being tested modifies the object
+# being tested, e.g., "a++".
+#
+# These options must be passed LAST to CompileExpression::test.
+#
+# Examples:
+#
+# Both "code" and "print" tests are expected to xfail:
+# CompileExpression add_imp "foo" 3 -compile {xfail *-*-*} -print {xfail *-*-*}
+#
+# The "print $VARIABLE" portion of the "code" test is expected to kfail
+# (the actual "compile code" GDB command will succeed), but the "print"
+# test should pass:
+# CompileExpression add_imp "foo" 3 -value {kfail *-*-* gdb/1234}
