<h2><a name="org">Testsuite organization and naming conventions</a></h2>
|
||||
<p>
|
||||
The directory <em>libsrcdir/testsuite</em> contains the test
|
||||
files, test harness, and utility information for verifying the
|
||||
correctness of C++ library on a given host. It includes the
|
||||
following directories, each named after a specific chapter of
|
||||
the C++ standard, and each containing test files or
|
||||
subdirectories of test files that test for that particular part
|
||||
of the standard.
|
||||
<p>
|
||||
|
||||
<pre>
|
||||
17_intro
|
||||
18_support
|
||||
19_diagnostics
|
||||
20_util
|
||||
21_strings
|
||||
22_locale
|
||||
23_containers
|
||||
25_algorithms
|
||||
26_numerics
|
||||
27_io
|
||||
</pre>
|
||||
|
||||
<p>
|
||||
In addition, the following directories include test files:
|
||||
</p>
|
||||
|
||||
<pre>
|
||||
backward Tests for backwards compatibility and deprecated features.
|
||||
demangle Tests for __cxa_demangle, the IA 64 C++ ABI demangler
|
||||
ext Tests for extensions.
|
||||
performance Tests for performance analysis, and performance regressions.
|
||||
thread Tests for threads.
|
||||
</pre>
|
||||
|
||||
<p>
|
||||
Some directories don't have test files, but instead contain
|
||||
auxiliary information:
|
||||
</p>
|
||||
|
||||
<pre>
|
||||
config Files for the dejagnu test harness.
|
||||
lib Files for the dejagnu test harness.
|
||||
libstdc++-v3.dg Files for the dejagnu test harness.
|
||||
data Sample text files for testing input and output.
|
||||
</pre>
|
||||
|
||||
<p>
|
||||
Within a directory that includes test files, there may be
|
||||
additional subdirectories, or files: this particular point is in
|
||||
flux. Originally, test cases were appended to one file that
|
||||
represented a particular section of the chapter under test, and
|
||||
was named accordingly. For instance, to test items related to
|
||||
<code> 21.3.6.1 - basic_string::find [lib.string::find]</code>
|
||||
in the standard, the following was used:
|
||||
<p>
|
||||
<pre>
|
||||
21_strings/find.cc
|
||||
</pre>
|
||||
<p>
|
||||
However, that practice soon became a liability as the test cases
|
||||
became huge and unwieldy, and testing new or extended
|
||||
functionality (like wide characters or named locales) became
|
||||
frustrating, leading to aggressive pruning of test cases on some
|
||||
platforms that covered up implementation errors. Now, the test
|
||||
suite is converging on a policy of one file, one test case,
|
||||
which solves the above issues and gives finer grained results
|
||||
and more manageable error debugging. As an example, the test case
|
||||
quoted above becomes:
|
||||
</p>
|
||||
<pre>
|
||||
21_strings/basic_string/find/char/1.cc
|
||||
21_strings/basic_string/find/char/2.cc
|
||||
21_strings/basic_string/find/char/3.cc
|
||||
21_strings/basic_string/find/wchar_t/1.cc
|
||||
21_strings/basic_string/find/wchar_t/2.cc
|
||||
21_strings/basic_string/find/wchar_t/3.cc
|
||||
</pre>
|
||||
|
||||
<p>
|
||||
All new tests should be written with the policy of one test
|
||||
case, one file in mind. At some point the entire testsuite will
|
||||
be converted: the current status is that the 21_string,
|
||||
22_locale, 27_io, and demangle directories have all been
|
||||
transitioned.
|
||||
</p>
|
||||
|
||||
<p>
|
||||
In addition, there are some special names and suffixes that are
|
||||
used within the testsuite to designate particular kinds of
|
||||
tests.
|
||||
</p>
|
||||
|
||||
<ul>
|
||||
<li>
|
||||
<em>_xin.cc</em>
|
||||
<p>
|
||||
This test case expects some kind of interactive input in order
|
||||
to finish or pass. At the moment, the interactive tests are not
|
||||
run by default. Instead, they are run by hand, like:
|
||||
<pre>
|
||||
g++ 27_io/objects/char/3_xin.cc
|
||||
cat 27_io/objects/char/3_xin.in | a.out
|
||||
</pre>
|
||||
</p>
|
||||
</li>
|
||||
<li>
|
||||
<em>.in</em>
|
||||
<p>
|
||||
This file contains the expected input for the corresponding <em>
|
||||
_xin.cc</em> test case.
|
||||
</p>
|
||||
</li>
|
||||
<li>
|
||||
<em>_neg.cc</em>
|
||||
<p>
|
||||
This test case is expected to fail: it's a negative test. At the
|
||||
moment, these are almost always compile time errors.
|
||||
</p>
|
||||
</li>
|
||||
<li>
|
||||
<em>char</em>
|
||||
<p>
|
||||
This can either be a directory name or part of a longer file
|
||||
name, and indicates that this file, or the files within this
|
||||
directory are testing the <code>char</code> instantiation of a
|
||||
template.
|
||||
</p>
|
||||
</li>
|
||||
<li>
|
||||
<em>wchar_t</em>
|
||||
<p>
|
||||
This can either be a directory name or part of a longer file
|
||||
name, and indicates that this file, or the files within this
|
||||
directory are testing the <code>wchar_t</code> instantiation of
|
||||
a template. Some hosts do not support <code>wchar_t</code>
|
||||
functionality, so for these targets, all of these tests will not
|
||||
be run.
|
||||
</p>
|
||||
</li>
|
||||
<li>
|
||||
<em>performance</em>
|
||||
<p>
|
||||
This can either be an enclosing directory name or part of a
|
||||
specific file name. This indicates a test that is used to
|
||||
analyze runtime performance, for performance regression testing,
|
||||
or for other optimization related analysis. At the moment, these
|
||||
test cases are not run by default, and instead assumed to be run
|
||||
manually.

||||

<h2><a name="util">Utilities: abicheck and libv3test</a></h2>
|

<p>
|
||||
The testsuite directory also contains some files that implement
|
||||
functionality that is intended to make writing test cases easier,
|
||||
or to avoid duplication, or to provide error checking in a way that
|
||||
is consistent across platforms and test harnesses. A stand-alone
|
||||
executable, called <em>abi_check</em>, and a static library called
|
||||
<em>libv3test</em> are constructed during the build. Both of these
|
||||
items are not installed, and only used during testing.
|
||||
</p>
|
||||
|

<p>
|

<h2><a name="new">How to write a new test case</a></h2>
|
||||
|
||||
<p>
|
||||
The first step in making a new test case is to choose the correct
|
||||
directory and file name, given the organization as previously
|
||||
described.
|
||||
</p>
|
||||
|
||||
<p>
|
||||
All files are copyright the FSF, and GPL'd: this is very
|
||||
important. The first copyright year should correspond to the date
|
||||
the file was checked in to CVS.
|
||||
</p>
|
||||
|
||||
<p>
|
||||
As per the dejagnu instructions, always return 0 from main to
|
||||
indicate success.
|
||||
</p>
|
||||
|
||||
<p>
|
||||
A bunch of utility functions and classes have already been
|
||||
abstracted out into the testsuite utility library, <code>
|
||||
libv3test</code>. To use this functionality, just include the
|
||||
appropriate header file: the library will automatically be linked
|
||||
in as part of the testsuite run.
|
||||
</p>
|
||||
|
||||
<p>
|
||||
For a test that needs to take advantage of the dejagnu test
|
||||
harness, what follows below is a list of special keyword that
|
||||
harness uses. Basically, a test case contains dg-keywords (see
|
||||
dg.exp) indicating what to do and what kinds of behavior are to be
|
||||
expected. New test cases should be written with the new style
|
||||
DejaGnu framework in mind.
|
||||
</p>
|
||||
|
||||
<p>
|
||||
To ease transition, here is the list of dg-keyword documentation
|
||||
lifted from dg.exp.
|
||||
</p>
|
||||
|
||||
<pre>
|
||||
# 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 test case 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 1: Testing compilation only
|
||||
// { dg-do compile }
|
||||
|

<h2><a name="check">Options for running the tests</a></h2>
|
||||
|
||||
<p> There are several ways to run the testsuite. There are two
|
||||
harnesses, one using dejagnu and one using bash. In addition, there
|
||||
is a special rule for checking the ABI of the shared library.
|
||||
</p>
|
||||
|
||||
<p>You can check the status of the build without installing it
|
||||
using the dejagnu harness, much like the rest of the gcc tools.</p>
|
||||
<p>
|
||||
<pre> make check</pre> in the <em>libbuilddir</em> directory.</p>
|
||||
<p>or</p>
|
||||
<p><pre> make check-target-libstdc++-v3</pre> in the
|
||||
<em>gccbuilddir</em> directory.</p>
|
||||
|
||||
<p>
|
||||
These commands are equivalent and will create a 'testsuite'
|
||||
directory underneath <em>libbuilddir</em> containing the results
|
||||
of the tests. Two results files will be generated: <em>
|
||||
libstdc++-v3.sum</em>, which is a PASS/FAIL summary for each
|
||||
test, and <em>libstdc++.log</em> which is a log of the exact
|
||||
command line passed to the compiler, the compiler output, and
|
||||
the executable output (if any). In addition, four files are
|
||||
generated that determine what test files are run. These files
|
||||
are:
|
||||
</p>
|
||||
|
||||
<ul>
|
||||
<li>
|
||||
<em>testsuite_files </em>
|
||||
<p> This is a list of all the test cases that will be run. Each
|
||||
test case is on a separate line, given with an absolute path
|
||||
from the <em>libsrcdir/testsuite</em> directory.
|
||||
</p>
|
||||
</li>
|
||||
|
||||
<li>
|
||||
<em>testsuite_files_interactive </em>
|
||||
<p> This is a list of all the interactive test cases, using the
|
||||
same format as the file list above. These tests are not run by default.
|
||||
</p>
|
||||
</li>
|
||||
|
||||
<li>
|
||||
<em>testsuite_files_performance</em>
|
||||
<p> This is a list of all the performance test cases, using the
|
||||
same format as the file list above. These tests are not run by default.
|
||||
</p>
|
||||
</li>
|
||||
|
||||
<li>
|
||||
<em>testsuite_wchar_t </em>
|
||||
<p> This file indicates that the host system can run the wchar_t
|
||||
tests, and corresponds to the macro definition <code>
|
||||
_GLIBCPP_USE_WCHAR_T</code> in the file c++config.h.
|
||||
</p>
|
||||
</li>
|
||||
</ul>
|
||||
|
||||
<p>
|
||||
To debug the dejagnu test harness during runs, try invoking with a
|
||||
specific argument to the variable RUNTESTFLAGS, as below.
|
||||
</p>
|
||||
|
||||
<pre>
|
||||
make check-target-libstdc++-v3 RUNTESTFLAGS="-v"
|
||||
</pre>
|
||||
or
|
||||
<pre>
|
||||
make check-target-libstdc++-v3 RUNTESTFLAGS="-v -v"
|
||||
</pre>
|
||||
|
||||
There are two ways to run on a simulator: set up DEJAGNU to point to a
|
||||
specially crafted site.exp, or pass down --target_board flags.
|
||||
|
||||
Example flags to pass down for various embedded builds are as follows:
|
||||
|
||||
<pre>
|
||||
--target=powerpc-eabism (libgloss/sim)
|
||||
make check-target-libstdc++-v3 RUNTESTFLAGS="--target_board=powerpc-sim"
|
||||
|
||||
--target=calmrisc32 (libgloss/sid)
|
||||
make check-target-libstdc++-v3 RUNTESTFLAGS="--target_board=calmrisc32-sid"
|
||||
|
||||
--target=xscale-elf (newlib/sim)
|
||||
make check-target-libstdc++-v3 RUNTESTFLAGS="--target_board=arm-sim"
|
||||
</pre>
|
||||
|
||||
<p> In addition, there are some testing options that are mostly of
|
||||
interest to library maintainers and system integrators. As such,
|
||||
these tests may not work on all cpu and host combinations, and must
|
||||
be executed in the <em>libbuilddir</em> directory.</p> These options
|
||||
include, but are not necessarily limited to, the following:
|
||||
</p>
|
||||
|
||||
<p>
|
||||
The library can also be tested using a bash script, instead of
|
||||
the default dejagnu test harness.
|
||||
</p>
|
||||
<pre>
|
||||
make check-script</pre>
|
||||
<p>
|
||||
These commands use the generated test_file lists as above, but
|
||||
run all the tests using both shared and static linking, and in
|
||||
addition provide some additional diffing of expected output
|
||||
files for the input/output tests. (This added diff may or may
|
||||
not be useful or necessary at the moment.) In addition, these
|
||||
tests provide size information for all the generated test cases,
|
||||
so that size data for new compiler or linker features can be
|
||||
collected. At one time timing information was attempted, so that
|
||||
compile speeds, link speeds, etc. could be measured, however at
|
||||
the moment all timing information is currently disabled.
|
||||
</p>
|
||||
|
||||
<pre>
|
||||
make check-script-install</pre>
|
||||
<p> As directly above, but tests an installed library, not the
|
||||
library and compiler in the build tree.
|
||||
</p>
|
||||
|
||||
<pre>
|
||||
make check-abi</pre>
|
||||
<p>The library ABI can be tested. This involves testing the shared
|
||||
library against an ABI-defining previous version.</p>
|
||||
|
||||
<p>
|
||||
We are interested in any strange failures of the
|
||||
testsuite; please see <a href="faq/index.html#2_4">FAQ 2.4</a>
|

for which files to examine.

The V3 testing framework supports, or will eventually support,

additional keywords for the purpose of easing the job of writing

test cases. All V3-keywords are of the form @xxx@. Currently plans

for supported keywords include:

</p>
|

|

@require@ <files>
|

The existence of <files> is essential for the test to complete
|
||||
successfully. For example, a test case foo.C using bar.baz as
|
||||
input file could say
|
||||
// @require@ bar.baz
|
||||
The special variable % stands for the rootname, e.g. the
|

file-name without its `.C' extension. Example of use (taken

verbatim from 27_io/filebuf.cc)
|
||||
// @require@ %-*.tst %-*.txt
|
||||
|
||||
@diff@ <first-list> <second-list>
|
||||
After the test case compiles and ran successfully, diff
|
||||
<first-list> against <second-list>, these lists should have the
|

same length. The test fails if diff returns non-zero a pair of

files.

We're in the process of converting the existing testsuite machinery to
|
||||
use the new style DejaGnu framework. Eventually, we'll abandon
|
||||
../mkcheck.in in favor of this new testsuite framework.
|
||||
|
||||
// 1: Thoughts on naming test cases, and structuring them.
|
||||
The testsuite directory has been divided into 11 directories, directly
|
||||
correlated to the relevant chapters in the standard. For example, the
|
||||
directory testsuite/21_strings contains tests related to "Chapter 21,
|
||||
Strings library" in the C++ standard.
|
||||
|
||||
So, the first step in making a new test case is to choose the correct
|
||||
directory. The second item is seeing if a test file exists that tests
|
||||
the item in question. Generally, within chapters test files are named
|
||||
after the section headings in ISO 14882, the C++ standard. For instance,
|
||||
|
||||
21.3.7.9 Inserters and Extractors
|
||||
|
||||
Has a related test case:
|
||||
21_strings/inserters_extractors.cc
|
||||
|
||||
Not so hard. Some time, the words "ctor" and "dtor" are used instead
|
||||
of "construct", "constructor", "cons", "destructor", etc. Other than
|
||||
that, the naming seems mostly consistent. If the file exists, add a
|
||||
test to it. If it does not, then create a new file. All files are
|
||||
copyright the FSF, and GPL'd: this is very important.
|
||||
|
||||
In addition, some of the locale and io code tests different
|
||||
instantiating types: thus, 'char' or 'wchar_t' is appended to the name
|
||||
as constructed above.
|
||||
|
||||
Also, some test files are negative tests. That is, they are supposed
|
||||
to fail (usually this involves making sure some kind of construct gets
|
||||
an error when it's compiled.) These test files have 'neg' appended to
|
||||
the name as constructed above.
|
||||
|
||||
Inside a test file, the plan is to test the relevant parts of the
|
||||
standard, and then add specific regressions as additional test
|
||||
functions, ie test04() can represent a specific regression noted in
|
||||
GNATS. Once test files get unwieldy or too big, then they should be
|
||||
broken up into multiple sub-categories, hopefully intelligently named
|
||||
after the relevant (and more specific) part of the standard.
|
||||
|
||||
|
||||
// 2: How to write a test case, from a dejagnu perspective
|
||||
As per the dejagnu instructions, always return 0 from main to indicate
|
||||
success.
|
||||
|
||||
Basically, a test case contains dg-keywords (see dg.exp) indicating
|
||||
what to do and what kinds of behaviour are to be expected. New
|
||||
testcases should be written with the new style DejaGnu framework in
|
||||
mind.
|
||||
|
||||
To ease transition, here is the list of dg-keyword documentation
|
||||
lifted from dg.exp -- eventually we should improve DejaGnu
|
||||
documentation, but getting checkin account currently demands Pyrrhic
|
||||
effort.
|
||||
|
||||
# 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 1: Testing compilation only
|
||||
(to just have a testcase do compile testing, without linking and executing)
|
||||
// { dg-do compile }
|
||||
|
||||
Example 2: Testing for expected warings on line 36
|
||||
// { dg-warning "string literals" "" { xfail *-*-* } 36
|
||||
|
||||
Example 3: Testing for compilation errors on line 41
|
||||
// { dg-do compile }
|
||||
// { dg-error "no match for" "" { xfail *-*-* } 41 }
|
||||

||||
More examples can be found in the libstdc++-v3/testsuite/*/*.cc files.

|
||||
// 3: Test harness notes, invocation, and debugging.
|
||||
Configuring the dejagnu harness to work with libstdc++-v3 in a cross
|
||||
compilation environment has been maddening. However, it does work now,
|
||||
and on a variety of platforms. Including solaris, linux, and cygwin.
|
||||
|
||||
To debug the test harness during runs, try invoking with
|
||||
|
||||
make check-target-libstdc++-v3 RUNTESTFLAGS="-v"
|
||||
or
|
||||
make check-target-libstdc++-v3 RUNTESTFLAGS="-v -v"
|
||||
|
||||
There are two ways to run on a simulator: set up DEJAGNU to point to a
|
||||
specially crafted site.exp, or pass down --target_board flags.
|
||||
|
||||
Example flags to pass down for various embedded builds are as follows:
|
||||
|
||||
--target=powerpc-eabism (libgloss/sim)
|
||||
make check-target-libstdc++-v3 RUNTESTFLAGS="--target_board=powerpc-sim"
|
||||
|
||||
--target=calmrisc32 (libgloss/sid)
|
||||
make check-target-libstdc++-v3 RUNTESTFLAGS="--target_board=calmrisc32-sid"
|
||||
|
||||
--target=xscale-elf (newlib/sim)
|
||||
make check-target-libstdc++-v3 RUNTESTFLAGS="--target_board=arm-sim"
|
||||
|
||||
|
||||
// 4: Future plans, to be done
|
||||
Shared runs need to be implemented, for targets that support shared libraries.
|
||||
|
||||
Diffing of expected output to standard streams needs to be finished off.
|
||||
|
||||
The V3 testing framework supports, or will eventually support,
|
||||
additional keywords for the purpose of easing the job of writing
|
||||
testcases. All V3-keywords are of the form @xxx@. Currently plans
|
||||
for supported keywords include:
|
||||
|
||||
@require@ <files>
|
||||
The existence of <files> is essential for the test to complete
|
||||
successfully. For example, a testcase foo.C using bar.baz as
|
||||
input file could say
|
||||
// @require@ bar.baz
|
||||
The special variable % stands for the rootname, e.g. the
|
||||
file-name without its `.C' extension. Example of use (taken
|
||||
verbatim from 27_io/filebuf.cc)
|
||||
// @require@ %-*.tst %-*.txt
|
||||
|
||||
@diff@ <first-list> <second-list>
|
||||
After the testcase compiles and ran successfully, diff
|
||||
<first-list> against <second-list>, these lists should have the
|
||||
same length. The test fails if diff returns non-zero a pair of
|
||||
files.
|
||||
|
||||
Current testing problems with cygwin-hosted tools:
|
||||
|
||||
There are two known problems which I have not addressed. The first is
|
||||
that when testing cygwin hosted tools from the unix build dir, it does
|
||||
the wrong thing building the wrapper program (testglue.c) because host
|
||||
and target are the same in site.exp (host and target are the same from
|
||||
the perspective of the target libraries)
|
||||
|
||||
Problem number two is a little more annoying. In order for me to make
|
||||
v3 testing work on Windows, I had to tell dejagnu to copy over the
|
||||
debug_assert.h file to the remote host and then set the includes to
|
||||
-I./. This is how all the other tests like this are done so I didn't
|
||||
think much of it. However, this had some unfortunate results due to
|
||||
gcc having a testcase called "limits" and C++ having an include file
|
||||
called "limits". The gcc "limits" binary was in the temporary dir
|
||||
when the v3 tests were being built. As a result, the gcc "limits"
|
||||
binary was being #included rather than the intended one. The only way
|
||||
to fix this is to go through the testsuites and make sure binaries are
|
||||
deleted on the remote host when testing is done with them. That is a
|
||||
lot more work than I want to do so I worked around it by cleaning out
|
||||
D:\kermit on compsognathus and rerunning tests.
