New Revision: 222393<br class="">
<br class="">
URL: <a href="http://llvm.org/viewvc/llvm-project?rev=222393&view=rev" target="_blank" class="">http://llvm.org/viewvc/llvm-project?rev=222393&view=rev</a><br class="">
Log:<br class="">
[CMake] Always include the Clang repo version, just like the autoconf build.<br class="">
<br class="">
Now that LLVM's helper script GetSVN.cmake actually works consistently,<br class="">
there's no reason not to use it. We avoid having to regenerate SVNVersion.inc<br class="">
every time by marking it as dependent on Git's reflog or SVN's entries file.<br class="">
<br class="">
This should end most of the issues of the AST format changing and breaking<br class="">
old module files: CMake-Clang should now detect that the version changed just<br class="">
like Autoconf-Clang has.<br class="">
<br class="">
Based on r190557. Depends on LLVM r222391.<br class="">
