I'm pretty sure that the output tells you that there's no makefile to execute such commands. If you didn't know it, LLVM makes use of cmake, so you make have to generate your makefile with "cmake ." (or at least that's the way I remembered it). Then type make.

That's probably not the problem. SAFECode does not use cmake at present.

First, Nikhail, were you able to compile the other components of SAFECode on Windows (namely, safecode/lib and safecode/runtime)? Also, were you able to compile unmodified clang and use it on Windows? You need to verify that these things work. If regular Clang doesn't work on Windows, SAFECode Clang won't work, either.

Second, to answer your specific question, you are probably seeing this problem because SAFECode needs to be reintegrated into Clang. The way we do that is to:

Remove the old safecode/tools/clang directory.
Use svn copy to copy clang into safecode/tools/clang
Modify the Makefiles in safecode/tools/clang so that clang can compile from within the SAFECode source tree.
Modify safecode/tools/clang so that it runs the SAFECode passes when the -fmemsafety option is used.

I have done steps 1 and 2. Peter is currently working on step 3. I recommend you help him on Step 3. Step 3 requires understanding LLVM Makefiles (http://llvm.org/docs/MakefileGuide.html). I sent a patch to you and Peter showing how I integrated SAFECode into Clang for LLVM 3.2. You can use that as a guide to integrating SAFECode into LLVM 3.7. I have attached it here for reference.

So, to recap:

Let me know if regular Clang works on Windows.
If regular Clang works, try to help Peter with Step 3.

Regards,

John Criswell

Documentation comment support

Clang now supports documentation comments written in a Doxygen-like syntax. -Clang parses the comments and can detect syntactic and semantic errors in -comments. These warnings are off by default. Pass -Wdocumentation -flag to enable warnings about documentation comments.

-
For example, given:

/// \param [in] Str the string.
-/// \returns a modified string.
-void do_something(const std::string &str);

-
clang -Wdocumentation will emit two warnings:

doc-test.cc:3:6: warning: '\returns' command used in a comment that is attached to a function returning void [-Wdocumentation]
-/// \returns a modified string.
-    ~^~~~~~~~~~~~~~~~~~~~~~~~~~
-doc-test.cc:2:17: warning: parameter 'Str' not found in the function declaration [-Wdocumentation]
-/// \param [in] Str the string.

-/// \param [in] Str the string.
-                ^

libclang includes a new API, clang_FullComment_getAsXML, to convert -comments to XML documents. This API can be used to build documentation -extraction tools.

C++11 Feature Support

Clang 3.2 supports most of the language features - added in the latest ISO C++ standard,C++ 2011. - Use -std=c++11 or -std=gnu++11 to enable support for these features. In addition to the features supported by Clang 3.1, the - following features have been added:

Implemented the C++11 discarded value expression rules for volatile lvalues.
Support for the C++11 enum forward declarations.
Handling of C++11 attribute namespaces (automatically).
Implemented C++11 [conv.prom]p4: an enumeration with a fixed underlying type has integral promotions - to both its underlying type and to its underlying type's promoted type.
