[Qbs] (no subject)

[Иван Комиссаров]

I did a small research and was able to compile a small example with clang-cl and asan.
Here are the flags I had to set manually:

cpp.optimization: "none"
    cpp.cxxFlags: [
        "/MT",
        "-fsanitize=address",
    ]
    cpp.linkerFlags: [
        "-wholearchive:C:\\Developer\\LLVM\\lib\\clang\\8.0.0\\lib\\windows\\clang_rt.asan-x86_64.lib",
        "-wholearchive:C:\\Developer\\LLVM\\lib\\clang\\8.0.0\\lib\\windows\\clang_rt.asan_cxx-x86_64.lib",
    ]
    cpp.staticLibraries: [
        "C:\\Developer\\LLVM\\lib\\clang\\8.0.0\\lib\\windows\\clang_rt.asan-x86_64.lib",
        "C:\\Developer\\LLVM\\lib\\clang\\8.0.0\\lib\\windows\\clang_rt.asan_cxx-x86_64.lib",
    ]

Probably, we should add some support for that in Qbs...
The problem is that qbs calls the linker directly (which is not the same clang-cl uses), maybe it’s worth using clang-cl for linking... or just add support for the usual clang with msvc ABI (I have plans for that for 1.16)
