And the truly final word for the moment : ) — I built a tool to partially automate the indentation workaround for LLVM 3.0 and it yields the same "co-processor offset out of range"/"unsupported relocation on symbol LCPI65_0" errors LLVM 3.3/3.4 did when it finally gets to integer-simple/GHC/Integer/Type.hs.

OK! So just to summarize: Building GHC HEAD with LLVM 3.0 or 3.2 (using GHC 7.6.3 as the bootstrap) on OS X 10.9 DP5/Xcode 5 DP5 exhibits very strange behavior wherein layout-based code along with mixed-tabs-and-spaces code fails to parse correctly, with issues in hundreds of files in the GHC HEAD tree. I don't have a 10.8 machine to check if this is a 10.9 exclusive issue, so I'd love if someone can try using these binaries to build GHC HEAD: http://llvm.org/releases/3.0/clang+llvm-3.0-x86_64-apple-darwin11.tar.gz
Building GHC HEAD with LLVM 3.3 or 3.4 works great as a regular compiler with the 10.9 workarounds I outlined in another thread, but fails when compiling as a cross-compiler (./configure --target=arm-apple-darwin10) with these errors: https://gist.github.com/lukexi/2b129f34fa027172c5ee
So I'm between a rock and a hard place at the moment.
The only (very tedious and slow) workaround I've found for the 3.0/3.2 bug is to manually expand tabs to spaces, and to transform do x y into do x y (similarly for where and let blocks)

Argh, sorry for the confusion: 3.2 *does* exhibit the issue. 3.3 and 3.4 do not.

Further investigation:
I grabbed 7.6.3 just to see if I somehow had a bad install of GHC, but the problem still occurred.
The problem only occurs with LLVM 3.0.
It is not related to cross-compilation or Stephen's patches: I tested this on multiple fresh clones with --with-gcc=clang.
LLVM 3.2, 3.3 and 3.4 do not exhibit the issue.
If anyone wants to try to reproduce, you can grab the LLVM 3.0 binaries here Clang Binaries for MacOS X/x86-64<http://llvm.org/releases/3.0/clang+llvm-3.0-x86_64-apple-darwin11.tar.gz> and just drop them in your path.
(Stephen, I'm now trying your patch with LLVM 3.2)

There seem to be two classes of error: one is the layout issue above, but other files can be fixed by simply running 'expand' on them.

Hi Stephen/all,
I got LLVM 3.0 installed and started building again but hit a very strange problem now wherein tons of layout-based code (as in http://en.wikibooks.org/wiki/Haskell/Indentation) is suddenly erroring out, e.g. compiler/coreSyn/CoreUnfold.lhs:481:2: parse error (possibly incorrect indentation or mismatched brackets) (some files also seem to be triggered by mixed tabs and spaces)
I can fix the errors one by one by converting the code to use more concrete indentation (like do thing1 thing2 ) but it's all over the tree.
Anyone have any idea what might cause this?
Cheers Luke

Luke,
Try llvm version 3.0 - that's what I'm using, and it definitely worked before. llvm-3.1 is broken for GHC+ARM. As for llvm >= 3.2, I'm not sure if it's been fixed yet, but it wasn't working last time I tried a couple of months ago. I think this was because llvm is getting fussier about its input and GHC hasn't been "tightened up" yet.
It's really easy to build llvm from source.
