Hey Pete, I also tried CMAKE_CXX_FLAGS_RELEASE with the same effect. On Mon, Jul 20, 2015, at 09:34 AM, Pete Cooper wrote:> Hi Adrian > > I’m not sure if the CMAKE_CXX_FLAGS is used in LLVM.

I don’t know compiler-rt so i may not be any help, but other people who can help would find that useful too.

Adrian, What makes you think CMAKE_CXX_FLAGS isn’t being respected? The tests will always occur regardless of whether or not you set the CXX_FLAGS explicitly. -Chris> On Jul 20, 2015, at 9:36 AM, adek at adek.io wrote: > > > Hey Pete, > > I also tried CMAKE_CXX_FLAGS_RELEASE > with the same effect. > > On Mon, Jul 20, 2015, at 09:34 AM, Pete Cooper wrote: >> Hi Adrian >> >> I’m not sure if the CMAKE_CXX_FLAGS is used in LLVM.

[LLVMdev] CMake does not propagate flags to build
I regularly use '-DCMAKE_CXX_FLAGS' when configuring CLang/LLVM to distinguish my builds (Alpha/Beta/Final) or to build custom versions, usually by adding additional '-D' flags, but I discovered I had to add the ':STRING' qualifier to it when invoking 'cmake'. With 'gmake' this is equivalent to '--with-extra-options="whatever flags": -DCMAKE_CXX_FLAGS:STRING="whatever flags" This works regardless of whether it is a Debug or Release build.
