*	Add support for parameter attributes to the llvm BE binding	David Terei	2010-06-24	1	-2/+1
\| \| \| \| \| \|	These allow annotations of the code produced by the backend which should bring some perforamnce gains. At the moment the attributes aren't being used though.
*	More updates to datalayout description in llvm BE	David Terei	2010-06-22	1	-7/+9

*	Update datalayout info in llvm BE	David Terei	2010-06-22	1	-2/+2

*	Declare some top level globals to be constant when appropriate	David Terei	2010-06-21	1	-11/+14
\| \| \| \| \| \| \|	This involved removing the old constant handling mechanism which was fairly hard to use. Now being constant or not is simply a property of a global variable instead of a separate type.
*	Reduce the number of passes over the cmm in llvm BE	David Terei	2010-06-21	1	-13/+12
\|
*	Add win32 datalayout support to llvm backend	David Terei	2010-06-18	1	-3/+6
\|
*	Add support of TNTC to llvm backend	David Terei	2010-06-18	1	-30/+57
\| \| \| \| \| \| \|	We do this through a gnu as feature called subsections, where you can put data/code into a numbered subsection and those subsections will be joined together in descending order by gas at compile time.
*	Add new LLVM code generator to GHC. (Version 2)	David Terei	2010-06-15	1	-0/+91
	This was done as part of an honours thesis at UNSW, the paper describing the work and results can be found at: http://www.cse.unsw.edu.au/~pls/thesis/davidt-thesis.pdf A Homepage for the backend can be found at: http://hackage.haskell.org/trac/ghc/wiki/Commentary/Compiler/Backends/LLVM Quick summary of performance is that for the 'nofib' benchmark suite, runtimes are within 5% slower than the NCG and generally better than the C code generator. For some code though, such as the DPH projects benchmark, the LLVM code generator outperforms the NCG and C code generator by about a 25% reduction in run times.
