Alp Toker b1d6b8ea7d CMake: fix compiler feature detection ... add_flag_if_supported() and add_flag_or_print_warning() were effectively no-ops, just returning the value of the first result (usually '-fno-omit-frame-pointer') for all subsequent checks for different flags. Due to the way CMake caches feature detection results, we need to provide symbolic variable names which will persist the cached results. This commit fixes feature detection using these two macros. The feature checks now run and get stored correctly, and the correct output can be observed in configure logs: -- Performing Test C_SUPPORTS_FPIC -- Performing Test C_SUPPORTS_FPIC - Success -- Performing Test CXX_SUPPORTS_FPIC -- Performing Test CXX_SUPPORTS_FPIC - Success git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@212586 91177308-0d34-0410-b5e6-96231b3b80d8		2014-07-09 03:38:19 +00:00
