Subject: clang: Enable cmake flags for llvm, clang, lld tests
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=c926c4f9f7ecf22698b7426609f8806feee175ca;p=thirdparty%2Fopenembedded%2Fopenembedded-core.git

clang: Enable cmake flags for llvm, clang, lld tests

Enable the necessary CMake flags to build and run tests
for LLVM, Clang and LLD. Install the LLVM target tools
needed to run tests via llvm-lit inside QEMU only when
CLANG_ENABLE_TESTSUITE = "1".
