# This file was written by Doug Evans (dje@cygnus.com).
23
# This file is based on old-dejagnu.exp. It is intended to be more extensible
24
# without incurring the overhead that old-dejagnu.exp can. All test framework
25
# commands appear in the testcase as "{ dg-xxx args ... }". We pull them out
26
# with one grep, and then run the function(s) named by "dg-xxx". When running
27
# dg-xxx, the line number that it occurs on is always passed as the first
28
# argument. We also support different kinds of tools via callbacks.
30
# The currently supported options are:
35
# dg-options "options ..." [{ target selector }]
36
# specify special options to pass to the tool (eg: compiler)
38
# dg-do do-what-keyword [{ target/xfail selector }]
39
# `do-what-keyword' is tool specific and is passed unchanged to
40
# ${tool}-dg-test. An example is gcc where `keyword' can be any of:
41
# preprocess|compile|assemble|link|run
42
# and will do one of: produce a .i, produce a .s, produce a .o,
43
# produce an a.out, or produce an a.out and run it (the default is
46
# dg-error regexp comment [{ target/xfail selector } [{.|0|linenum}]]
47
# indicate an error message <regexp> is expected on this line
48
# (the test fails if it doesn't occur)
49
# Linenum=0 for general tool messages (eg: -V arg missing).
50
# "." means the current line.
52
# dg-warning regexp comment [{ target/xfail selector } [{.|0|linenum}]]
53
# indicate a warning message <regexp> is expected on this line
54
# (the test fails if it doesn't occur)
56
# dg-bogus regexp comment [{ target/xfail selector } [{.|0|linenum}]]
57
# indicate a bogus error message <regexp> use to occur here
58
# (the test fails if it does occur)
60
# dg-build regexp comment [{ target/xfail selector }]
61
# indicate the build use to fail for some reason
62
# (errors covered here include bad assembler generated, tool crashes,
64
# (the test fails if it does occur)
66
# dg-excess-errors comment [{ target/xfail selector }]
67
# indicate excess errors are expected (any line)
68
# (this should only be used sparingly and temporarily)
70
# dg-output regexp [{ target selector }]
71
# indicate the expected output of the program is <regexp>
72
# (there may be multiple occurrences of this, they are concatenated)
74
# dg-final { tcl code }
75
# add some tcl code to be run at the end
76
# (there may be multiple occurrences of this, they are concatenated)
77
# (unbalanced braces must be \-escaped)
79
# "{ target selector }" is a list of expressions that determine whether the
80
# test succeeds or fails for a particular target, or in some cases whether the
81
# option applies for a particular target. If the case of `dg-do' it specifies
82
# whether the testcase is even attempted on the specified target.
84
# The target selector is always optional. The format is one of:
86
# { xfail *-*-* ... } - the test is expected to fail for the given targets
87
# { target *-*-* ... } - the option only applies to the given targets
89
# At least one target must be specified, use *-*-* for "all targets".
90
# At present it is not possible to specify both `xfail' and `target'.
91
# "native" may be used in place of "*-*-*".
95
# [ ... some complicated code ... ]
96
# return a; /* { dg-build "fatal" "ran out of spill regs" { xfail i386-*-* } } */
98
# In this example, the compiler use to crash on the "return a;" for some
99
# target and that it still does crash on i386-*-*. Admittedly, this is a
102
# ??? It might be possible to add additional optional arguments by having
103
# something like: { dg-error ".*syntax.*" "syntax error" { { foo 1 } ... } }
107
# ${tool}-dg-test testfile do-what-keyword extra-flags
109
# Run the test, be it compiler, assembler, or whatever.
111
# ${tool}-dg-prune target_triplet text
113
# Optional callback to delete output from the tool that can occur
114
# even in successful ("pass") situations and interfere with output
115
# pattern matching. This also gives the tool an opportunity to review
116
# the output and check for any conditions which indicate an "untested"
117
# or "unresolved" state. An example is if a testcase is too big and
118
# fills all available ram (which can happen for 16 bit cpus). The
119
# result is either the pruned text or
120
# "::untested|unresolved|unsupported::message"
121
# (eg: "::unsupported::memory full").
124
# 1) All runnable testcases must return 0 from main() for success.
125
# You can't rely on getting any return code from target boards, and the
126
# `exec' command says a program fails if it returns non-zero.
128
# Language independence is (theoretically) achieved by:
130
# 1) Using global $tool to indicate the language (eg: gcc, g++, gas, etc.).
131
# This should only be used to look up other objects. We don't want to
132
# have to add code for each new language that is supported. If this is
133
# done right, no code needs to be added here for each new language.
135
# 2) Passing tool options in as arguments.
137
# Earlier versions of ${tool}_start (eg: gcc_start) would only take the name
138
# of the file to compile as an argument. Newer versions accept a list of
139
# one or two elements, the second being a string of *all* options to pass
140
# to the tool. We require this facility.
144
# Try not to do anything else that makes life difficult.
146
# The normal way to write a testsuite is to have a .exp file containing:
148
# load_lib ${tool}-dg.exp
150
# dg-runtest [lsort [glob -nocomplain $srcdir/$subdir/foo*]] ...
153
# Global state variables.

# The defaults are for GCC.

# The default do-what keyword.
