Description of problem: Upstream llvm is moving to using cmake, we need to get our packages moved over. This move also allows us to build llvm in separate pieces, so we can split our llvm package up into llvm, clang, compiler-rt and lldb packages. This bug is a tracker for the reviews of the splits. https://fedorapeople.org/~airlied/llvm/cmake/llvm.spec is the proposed llvm spec file.
This doesn't build from just the spec file, you also need to copy llvm-config.h from the current llvm source package However with that in place, this looks good. I'd paste the fedora-review output here, but it doesn't seem to want to complete in bounded time (been running for hours now). I'v reviewed the clang lldb and compiler-rt packages too, once those git modules are created we can build this.
This bug appears to have been reported against 'rawhide' during the Fedora 24 development cycle. Changing version to '24'. More information and reason for this action is here: https://fedoraproject.org/wiki/Fedora_Program_Management/HouseKeeping/Fedora24#Rawhide_Rebase
