[llvm-dev] CMake option to disable LTO?

Wed Jan 13 11:26:06 PST 2016

Hi,

There is no option (that I know of) to enable/disable LTO (it shouldn’t be enabled) other than setting it explicitly in the CMAKE_C_FLAG/CMAKE_CXX_FLAG.

Are you sure LTO is enabled? What it the value of CMAKE_C_FLAG/CMAKE_CXX_FLAG in your CMakeCache.txt?
