Could we do it just for Rawhide for now at least. eg llvm-3.3 broke building with ghc badly on ARM (where the llvm backend is the default). I am not even sure if the coming ghc-7.8 release will support llvm-3.4. If someone has info on this it would be helpful. Jens, what is/was the problem with llvm and ghc? And which update do you mean? Is there a bug report or something? *** Bug 1049220 has been marked as a duplicate of this bug. *** (In reply to Jan Včelák from comment #2) > Jens, what is/was the problem with llvm and ghc? And which update do you > mean? Is there a bug report or something? ghc-7.6 only officially supports llvm-3.1 iirc... ghc only uses llvm as the default compiler backend on ARM. There are bunch of packages that fail to build in F20 on ARM because of this. The problem also affects Intel archs, but llvm is not normally used there by ghc so it is a lesser problem. I didn't file bug since llvm-3.3 was already in F20 before we fully bootstrapped/fixed ghc for F20 ARM so it seemed too late anyway. I can supply more details/bug lists if you want. I believe that ghc-7.8 "soon" to be released (hopefully in time for F21 at least) should support llvm-3.3. Not so sure about llvm-3.4... The unreleased LLVM 3.5 will be needed for Mesa 10.1 to properly support OpenGL 3.3 on radeonsi.
llvm-libs has its libraries under /usr/{lib,lib64}/llvm at the moment, it should be versioned. Now, if only the llvm binaries, like llc and other could be parallel installable... Wait, we have alternatives!
Alternatively it's possibly to install llvm-3.4 in parallel as an SCL[1] on F19 and F20 from the copr[2].

Works fine. Thanks! 3.4 is built for F20 now. Thanks! |
