[PATCH] D109593: WIP: [libcxx] Add a CI configuration for standalone building in llvm-project/runtimes

[Petr Hosek via Phabricator via llvm-commits]

phosek added inline comments.


================
Comment at: runtimes/CMakeLists.txt:77-82
 # This variable makes sure that e.g. llvm-lit is found.
-set(LLVM_MAIN_SRC_DIR ${LLVM_BUILD_MAIN_SRC_DIR})
+set(LLVM_MAIN_SRC_DIR ${CMAKE_CURRENT_SOURCE_DIR}/../llvm)
 set(LLVM_CMAKE_PATH ${LLVM_MAIN_SRC_DIR}/cmake/modules)
 
 # This variable is used by individual runtimes to locate LLVM files.
+set(LLVM_PATH ${CMAKE_CURRENT_SOURCE_DIR}/../llvm)
----------------
Can we land this change as a separate commit?


================
Comment at: runtimes/CMakeLists.txt:95
-if (NOT MSVC)
-  set(CMAKE_REQUIRED_FLAGS "${CMAKE_REQUIRED_FLAGS} -nostdinc++ -nostdlib++")
-endif()
----------------
Rather than removing this altogether, could we either check if the compiler supports these flags or if the compiler is Clang?

`-nostdinc++` should be support by GCC.

Comment at: runtimes/CMakeLists.txt:100-103
+if (NOT LLVM_DEFAULT_TARGET_TRIPLE)
+  include(GetHostTriple)
+  get_host_triple(LLVM_DEFAULT_TARGET_TRIPLE)
