+# This file was written by Doug Evans (dje@cygnus.com).
+
+# This file is based on old-dejagnu.exp. It is intended to be more extensible
+# without incurring the overhead that old-dejagnu.exp can. All test framework
+# commands appear in the testcase as "{ dg-xxx args ... }". We pull them out
+# with one grep, and then run the function(s) named by "dg-xxx". When running
+# dg-xxx, the line number that it occurs on is always passed as the first
+# argument. We also support different kinds of tools via callbacks.
+#
+# The currently supported options are:
+#
+# dg-prms-id N
+# set prms_id to N
+#
+# dg-options "options ..." [{ target selector }]
+# specify special options to pass to the tool (eg: compiler)
+#
+# dg-do do-what-keyword [{ target/xfail selector }]
+# `do-what-keyword' is tool specific and is passed unchanged to
+# ${tool}-dg-test. An example is gcc where `keyword' can be any of:
+# preprocess|compile|assemble|link|run
+# and will do one of: produce a .i, produce a .s, produce a .o,
+# produce an a.out, or produce an a.out and run it (the default is
+# compile).
+#
+# dg-error regexp comment [{ target/xfail selector } [{.|0|linenum}]]
+# indicate an error message <regexp> is expected on this line
+# (the test fails if it doesn't occur)
+# Linenum=0 for general tool messages (eg: -V arg missing).
+# "." means the current line.
+#
+# dg-warning regexp comment [{ target/xfail selector } [{.|0|linenum}]]
+# indicate a warning message <regexp> is expected on this line
+# (the test fails if it doesn't occur)
+#
+# dg-bogus regexp comment [{ target/xfail selector } [{.|0|linenum}]]
+# indicate a bogus error message <regexp> use to occur here
+# (the test fails if it does occur)
+#
+# dg-build regexp comment [{ target/xfail selector }]
+# indicate the build use to fail for some reason
+# (errors covered here include bad assembler generated, tool crashes,
+# and link failures)
+# (the test fails if it does occur)
+#
+# dg-excess-errors comment [{ target/xfail selector }]
+# indicate excess errors are expected (any line)
+# (this should only be used sparingly and temporarily)
+#
+# dg-output regexp [{ target selector }]
+# indicate the expected output of the program is <regexp>
+# (there may be multiple occurrences of this, they are concatenated)
+#
+# dg-final { tcl code }
+# add some tcl code to be run at the end
+# (there may be multiple occurrences of this, they are concatenated)
+# (unbalanced braces must be \-escaped)
+#
+# "{ target selector }" is a list of expressions that determine whether the
+# test succeeds or fails for a particular target, or in some cases whether the
+# option applies for a particular target. If the case of `dg-do' it specifies
+# whether the testcase is even attempted on the specified target.
+#
+# The target selector is always optional. The format is one of:
+#
+# { xfail *-*-* ... } - the test is expected to fail for the given targets
+# { target *-*-* ... } - the option only applies to the given targets
+#
+# At least one target must be specified, use *-*-* for "all targets".
+# At present it is not possible to specify both `xfail' and `target'.
+# "native" may be used in place of "*-*-*".
+#
+# Example:
+#
+# [ ... some complicated code ... ]
+# return a; /* { dg-build "fatal" "ran out of spill regs" { xfail i386-*-* } } */
+#
+# In this example, the compiler use to crash on the "return a;" for some
+# target and that it still does crash on i386-*-*. Admittedly, this is a
+# contrived example.
+#
+# ??? It might be possible to add additional optional arguments by having
+# something like: { dg-error ".*syntax.*" "syntax error" { { foo 1 } ... } }
+#
+# Callbacks
+#
+# ${tool}-dg-test testfile do-what-keyword extra-flags
+#
+# Run the test, be it compiler, assembler, or whatever.
+#
+# ${tool}-dg-prune target_triplet text
+#
+# Optional callback to delete output from the tool that can occur
+# even in successful ("pass") situations and interfere with output
+# pattern matching. This also gives the tool an opportunity to review
+# the output and check for any conditions which indicate an "untested"
+# or "unresolved" state. An example is if a testcase is too big and
+# fills all available ram (which can happen for 16 bit cpus). The
+# result is either the pruned text or
+# "::untested|unresolved|unsupported::message"
+# (eg: "::unsupported::memory full").
+#
+# Notes:
+# 1) All runnable testcases must return 0 from main() for success.
+# You can't rely on getting any return code from target boards, and the
+# `exec' command says a program fails if it returns non-zero.
+#
+# Language independence is (theoretically) achieved by:
+#
+# 1) Using global $tool to indicate the language (eg: gcc, g++, gas, etc.).
+# This should only be used to look up other objects. We don't want to
+# have to add code for each new language that is supported. If this is
+# done right, no code needs to be added here for each new language.
+#
+# 2) Passing tool options in as arguments.
+#
+# Earlier versions of ${tool}_start (eg: gcc_start) would only take the name
+# of the file to compile as an argument. Newer versions accept a list of
+# one or two elements, the second being a string of *all* options to pass
+# to the tool. We require this facility.
+#
+# 3) Callbacks.
+#
+# Try not to do anything else that makes life difficult.
+#
+# The normal way to write a testsuite is to have a .exp file containing:
+#
+# load_lib ${tool}-dg.exp
+# dg-init
+# dg-runtest [lsort [glob -nocomplain $srcdir/$subdir/foo*]] ...
+# dg-finish
+
+# Global state variables.
+# The defaults are for GCC.
+
+# The default do-what keyword.
+set dg-do-what-default compile
+
+# When dg-interpreter-batch-mode is 1, no execution test or excess error
+# tests are performed.
+set dg-interpreter-batch-mode 0
+
+# Line number format. This is how line numbers appear in program output.

+
+# Useful subroutines.
+
+# dg-get-options -- pick out the dg-xxx options in a testcase
+#
+# PROG is the file name of the testcase.
+# The result is a list of options found.
+#
+# Example: For the following testcase:
+#
+# /* { dg-prms-id 1234 } */
+# int foo { return 0; } /* { dg-build fatal "some comment" } */
