.... However, llvm-gcc complains about not recognizing them. I read that there is an -maltivec flag for the LLVM PowerPC backend, but my version of llvm-gcc complains about this "unrecognized command line option." Any hints? Thanks.

I was afraid of that. Any pointers on how to do this? I'm able to build llvm-gcc-4.2 x86 natively, but not the powerpc version....

Hi, Bernardo Fedora has a patch for LLVM 2.2 release with gcc 4.3 here: http://cvs.fedora.redhat.com/viewcvs/rpms/llvm/devel/llvm-2.2-gcc43.patch Just drop it in the llvm-2.2 directory and execute $ patch -p1 < llvm-2.2-gcc43.patch It should build cleanly afterwards. -- Sunjae Park MS.

...;llc -march c" output), so I'm a bit confused. I'm not looking for a target independent IR, either... Regarding building LLVM as a cross compiler, I assume it should be pretty much identical to building gcc as a cross compiler? (sans adding the LLVM_OBJ directory when configuring). -- Sunjae Park MS.
