38a1075865 It should be ok for a xform output type to be different from input type.

dc3605efdb Add support for generating vspltw, instead of a vperm instruction with a 
constant pool load.  This generates significantly nicer code for splats.

When tblgen gets bugfixed, we can remove the custom selection code.

f0effde00d Copy matching pattern's output type info to instruction result pattern. 
The instruction patterns do not contain enough information to resolve the
exact type of the destination if it of a generic vector type.

502bb9af8b The library dependency file in flat format. This file is generated by the 
makefile using the utils/GenLibDeps.pl script with the -flat option. It
records the dependencies between libraries in such a way that the
llvm-config script can easily read it (in makefile dependency format).

Reid Spencer
d6bae0ca62 First cut at the Makefile for llvm-config. This initial version just provides 
the rule for building the LibDeps.txt file using GenLibDeps.pl. This needs
to be done from time to time manually in order to keep LibDeps.txt up to
date.
