Re: [Haskell-cafe] LLVM Backend status
Great! Its very very nice to hear that! Has Haskell somewhere a technical documentation focused on LLVM usage?

And there was a lareg set of patches for the LLVM backend applied just now: http://www.haskell.org/pipermail/ghc-commits/2013-June/002324.html and the following 10 or so commit.

Currently for numerical code, the LLVM backend performs better than the native codegen. I also think that the LLVM backend is the only option for ARM. > 2) How can I generate the LLVM IR (or bc) files from the compiler?

As someone else stated, use `-keep-llvm-files` but be aware that GHC uses a custom calling convention so calling into GHC generated LLVM code is non-trivial.

You can use the `-keep-llvm-files` option for this. signature.asc Description: Digital signature ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
[Haskell-cafe] LLVM Backend status
Hi! I'm new to Haskell and I'm very interested in using it as a base layer for my application. I need to generate the LLVM-IR code from ghc compiler, so I've got 2 questuions to you: 1) Is the LLVM Backend actively developed or should I be afraid it will be discontinued or broken? 2) How can I generate the LLVM IR (or bc) files from the compiler? I see that durign compilation with -fllvm -v3 flags the bc files are created but they are immidietly (after usage) deleted - Is it possible to tell the compiler not to delete them? ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
