Re: Via LLVM on arm (Was: ANNOUNCE: GHC 7.4.1 Release Candidate 1)



Dear Karel again,

it’s still building locally (on and64), only then I can upload the
package and it will be attempted to be built for armel. One thing that
is worrying me is the llvm version. The "llvm" Debian package installs
llvm-2.9 in Debian, so /usr/bin/opt means the binary from the 2.9
package. There is a separate llvm-3.0 package available, which
ships /usr/bin/opt-3.0 etc.

Will it work with llvm-2.9, or will I need 3.0 (as hinted at in
http://ghcarm.wordpress.com/2011/11/03/llvm-patch-is-merged-for-inclusion-in-llvm-3-0-release/). In the latter case; what knobs do I have to turn so that ghc is _built_ using opt-3.0 and llc-3.0 _and_ these binaries are used by the generated ghc?

Greetings,
Joachim
