GHC 7.4.1 32 bit: LLVM backend fails on OSX 64bit

[dterei]

If running:

* GHC: 7.4.1, 32bit * OSX: 64 bit * LLVM: 3.0

Things fail because the correct 32bit mode flag isn't being passed to the clang compiler used by the LLVM backend as the assembler.

Work around for now is to compile using:

$ ghc -opta-m32 -fllvm

But need to fix for 7.4.2

[dterei]

Ian could you raise the priority of this to high please? I don't want it to be forgotten about for the 7.4.2 release.

Fixed. Please merge into a 7.4.2 release if there is one Ian.

[dterei]

OK I merged into branch ghc-7.4 as that seems to be the style.

Replying to dterei:

FYI: you can just put the ticket into the merge state and igloo will handle the merging.

[dterei]

That's what I normally do but people other than igloo seemed to be pushing patches into 7.4 branch... I'll stick with letting igloo handle from now on.
