In LLVM unified builds, Swift normally lives in
tools/swift
and the paths from the CMake build directory are not always the same as in a standalone build.Fix some tests using
%clang-include-dir
(which effectively points to$CMAKE_BUILD_ROOT/include
) to use the new%swift-include-dir
, which should point to the rightinclude/
directory in both unified and standalone builds.Additionally, change the calculation of
%clang-include-dir
to not be relative to theswift
binary, but to the CMake build root instead.
