      ClangStaticAnalyzer: Stop passing on toolchain defines for qmake/msvc case · 98b66534
      Nikolai Kosjar authored
      
      Re-produce with:
        1) Open qt-essential-includes.pro and configure it with a Qt 5.7.0 MSVC2013
           64 Bit Kit.
        2) Run the analyzer.
      
      Errors during analyzing occur in winnt.h [1]. This is somehow related to
      /D__int32=long that we pass on. Removing it helps.
      
      It looks like there is no reason anymore to pass on the toolchain defines with
      clang-3.8 at all. Our unit test projects can be parsed by the analyzer without
      them.
      
      Tested with the following kits:
      
      	Qt 5.6.0 (mingw39_32)
      	Qt 5.6.0 (msvc2013)
      	Qt 5.6.0 (msvc2013_64)
      	Qt 5.6.0 (msvc2015)
      	Qt 5.6.0 (msvc2015_64)
      	Qt 5.7.0 (mingw53_32)
      	Qt 5.7.0 (msvc2013)
      	Qt 5.7.0 (msvc2013_64)
      	Qt 5.7.0 (msvc2015)
      	Qt 5.7.0 (msvc2015_64)

      Clang: Pass on file paths with native separators · 36e7f454
      Nikolai Kosjar authored
      libclang 3.8 seems to be sensitive to file paths separators [1]. On Windows,
      this led to not updated document annotations and/or crashes after reparsing.
      
      When passing file paths to libclang, convert to native separators.
      When getting file paths from libclang, convert back.
      
      This handles:
       * main file path
       * file paths of the unsaved files
       * -I<DIR> arguments, the resource path (for builtins) and the paths to the
         wrapped qt headers
       * included header files from libclang
       * source locations from libclang
      
      Also, minimize the conversion in SourceLocation to a minimum by making
      filePath() lazy.
