[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.

All the best,

	MartinO

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.

[LLVMdev] CMake does not propagate flags to build

Hey,

Thanks for ideas. I tried them on, but none of them succeeded.

If I remove this line:
https://github.com/llvm-mirror/compiler-rt/blob/c9d8d35a5c2bdd6a0dd41f1b6cf3afb822df6a6e/CMakeLists.txt#L207

Everything is correctly built with -fno-omit-frame-pointer.

Any suggestion why it would be the case?

Thanks,
Adrian

[LLVMdev] CMake does not propagate flags to build

Wait… This is just for compiler-rt?

+Samsonov

I don’t know if we explicitly don’t support -fno-omit-frame-pointer for
compiler-rt, but in general compiler-rt is generally built differently from LLVM
& Clang for a reason.

Why do you need -fno-omit-frame-pointer for compiler-rt?

[LLVMdev] CMake does not propagate flags to build

This is just for compiler-rt. The reason for having
-fno-omit-frame-pointer is that tools like
https://perf.wiki.kernel.org/index.php/Main_Page would work on ASAN
binaries.
