Hi, I was having troubles building LLVM with Polly in-tree using CMake with LLVM_BUILD_32_BITS on. Turns out CMake considers LLVMPolly a module, not a shared library, and LLVM_BUILD_32_BITS only makes provisions for the EXE and SHARED linker flags. Possible fixes (pick one): 1. Change cmake/modules/HandleLLVMOptions.cmake to append -m32 to CMAKE_MODULE_LINKER_FLAGS as well if LLVM_BUILD_32...

...dbot [1] and it does not report any problems. Do you > understand why. I think so. This is an i?86 build on a x86_64 machine, i.e. with -m32. (gcc specifically, but I am sure that clang would raise the same issue, since this is about passing (or not passing) the correct flags to the linker. The LLVM_BUILD_32_BITS option seems to be the canonical way to request an i?86 build on a x86_64 machine when using CMake to build LLVM.) > I would go for option 1 as Polly itself is used not as a shared library, but > as a module. Would you be able to provide a patch? Sure; I have attached it. Cheers, ~~ Ondra...

Over the past few years the LLVM CMake build system has gained a lot of new features, which have powered new workflows and capabilities. This development has largely been individual efforts without focus or long-term direction. The build system is of incredible importance to LLVM as it is a primary interface for contributors to build and test their changes. This year, LLVM is making a huge

That seems to work (see below). $ cd
