+# "load_gcc_lib" will search the core compiler's .exp collection instead.

-## This file contains support routines for dg.exp based testsuite
-## framework.

-## The global associative array lib_env contains the totality
-## of options necessary to run testcases; the meanings of which are
-## as follows:
-## lib_env(CXX) The compiler used to run testcases.
-## lib_env(CXXFLAGS) Special flags passed to the compiler.
-## lib_env(LIBGLOSSFLAGS) Flags for finding libgloss-using xcompilers.
-## lib_env(INCLUDES) Includes options to pass to the compiler.
-## lib_env(LIBS) Libraries to link, and dditional library flags.
-## lib_env(LIBTOOL) Path to the `libtool' script.
-## lib_env(SRC_DIR) Where V3 master source lives.
-## lib_env(BUILD_DIR) Where V3 is built.
-## lib_env(static) Flags to pass to the linker to build a
-## statically linked executable.
-## lib_env(shared) Flags to pass to the linker to build a
-## dynamically linked executable.
-## lib_env(testcase_options) Options specified by current testcase.
-## These are specified through the @xxx@-keywords.
+# libstdc++_* callbacks we don't define, but could:
+# ..._option_help prints additional --help output
+# ..._option_proc (--foo) process our own options
+# ..._init (normal.exp) called once per test file
+# ..._finish bracketing function for libstdc++_init
+# ...-dg-prune removing output text, see top of system dg.exp
+#
+# Useful hook: if ${hostname}_init exists, it will be called, almost
+# the last thing before testing begins. This can be defined in, e.g.,
+# ~/.dejagnurc or $DEJAGNU.
