the following:</p>
<pre>
- python (path to llvm)/llvm/utils/lit/lit.py -sv --no-progress-bar
- (path to llvm)/llvm/tools/clang/test
+ python (path to llvm)\llvm\utils\lit\lit.py -sv
+ --param=build_mode=Win32 --param=build_config=Debug
+ --param=clang_site_config=(build dir)\tools\clang\test\lit.site.cfg
+ (path to llvm)\llvm\tools\clang\test
</pre>
<p>For CMake builds e.g. on Windows with Visual Studio, you will need
to specify your build configuration (Debug, Release, etc.) via
- <tt>--param=build_config=(build config)</tt>.</p>
+ <tt>--param=build_config=(build config)</tt>. You may also need to specify
+ the build mode (Win32, etc) via <tt>--param=build_mode=(build mode)</tt>.</p>
+
+ <p>Additionally, you will need to specify the lit site configuration which
+ lives in (build dir)\tools\clang\test, via
+ <tt>--param=clang_site_config=(build dir)\tools\clang\test\lit.site.cfg</tt>.
+ </p>
<p>To run a single test:</p>
<pre>
- python (path to llvm)/llvm/utils/lit/lit.py -sv --no-progress-bar
- (path to llvm)/llvm/tools/clang/test/(dir)/(test)
+ python (path to llvm)\llvm\utils\lit\lit.py -sv
+ --param=build_mode=Win32 --param=build_config=Debug
+ --param=clang_site_config=(build dir)\tools\clang\test\lit.site.cfg
+ (path to llvm)\llvm\tools\clang\test\(dir)\(test)
</pre>
<p>For example:</p>
<pre>
- python C:/Tools/llvm/utils/lit/lit.py -sv --no-progress-bar
- C:/Tools/llvm/tools/clang/test/Sema/wchar.c
+ python C:\Tool\llvm\utils\lit\lit.py -sv
+ --param=build_mode=Win32 --param=build_config=Debug
+ --param=clang_site_config=c:\Tools\build\tools\clang\test\lit.site.cfg
+ C:\Tools\llvm\tools\clang\test\Sema\wchar.c
</pre>
<p>The -sv option above tells the runner to show the test output if
any tests failed, to help you determine the cause of failure.</p>
+ <p>You can also pass in the --no-progress-bar option if you wish to disable
+ progress indications while the tests are running.</p>
+
<p>Your output might look something like this:</p>
- <pre>lit.py: lit.cfg:152: note: using clang: 'C:/Tools/llvm/bin/Release\\clang.EXE'
+ <pre>lit.py: lit.cfg:152: note: using clang: 'C:\Tools\llvm\bin\Release\clang.EXE'
