Optimized build

Clang Frontend
#1

I try to make a build directory with optimization in mind. But instead of

…/llvm/configure --enable-optimized --disable-assertions

I want to use cmake and ninja afterwards. I have tried various things but I can’t achieve what I want. cmake recognizes a variable for assertions (LLVM_ENABLE_ASSERTIONS=OFF) but I can’t find something similar for optimizations.

Is it possible to achieve what I try with ninja?

Thx in advance.

You can use -DCMAKE_BUILD_TYPE=Release to create a release build.
That turns on optimisations and turns off assertions by default;
LLVM_ENABLE_ASSERTIONS can be used to independently control assertions.

Thanks,

Peter solved your specific problem. For a more broad explanation about
