This is a new modernized VS integration installer. It adds a Visual Studio .sln file which, when built, outputs a VSIX that can be used to install ourselves as a "real" Visual Studio Extension. We can even upload this extension to the visual studio marketplace. This fixes a longstanding problem where we didn't support installing into VS 2017 and higher. In addition to supporting VS 2017, due to the way this is written we now longer need to do anything special to support future versions of VS as well. Everything should "just work". This also fixes several bugs with our old integration, such as MSBuild triggering full rebuilds when /Zi was used. Finally, we add a new UI page called "LLVM" which becomes visible when the LLVM toolchain is selected. For now this only contains one option which is the path to clang-cl.exe, but in the future we can add more things here. Differential Revision: https://reviews.llvm.org/D42762 llvm-svn: 337572

<!-- The general order of executing an MSBuild file is roughly:
|
|
1) vcxproj file
|
|
2) ├─ Import Microsoft.Cpp.props
|
|
3) │ └─ Import Toolset specific props (e.g. $(VCTargets)Platforms\Win32\PlatformToolsets\llvm\Toolset.props)
|
|
4) │ └─ Import This File (LLVM.Cpp.Common.props)
|
|
5) │─ Core logic of vcxproj (define files, override properties, etc)
|
|
6) └─ Import Microsoft.Cpp.targets
|
|
7) │─ Import Toolset specific targets file (e.g. $(VCTargets)Platforms\Win32\PlatformToolsets\llvm\Toolset.targets)
|
|
8) └─ Run the compiler.
|
|
The important thing is that we have hooks at 3, 4, and 7. 3 and 4 give
|
|
us the ability to provide initial values for toolchain settings (where
|
|
is the compiler, what values are considered "default" for a given
|
|
setting, etc), 7 gives us the ability to act on anything that the user
|
|
has overridden (such as warning or erroring on incompatible settings,
|
|
mapping settings to other settings, etc).
