Chris Lattner 924d100bd1 Cleanup a bunch of tests. In particular do not allow target directives in 
the .ll file or it forces the V9 backend.  This is the CodeGen/Generic dir,
so there is no use in doing that.

Chris Lattner 1ef74d6135 X86 BE requires SelectionDAG 
llvm-svn: 19337
 2005-01-07 07:51:25 +00:00
Chris Lattner 28ce94ce85 X86 JIT requires the selection dag library. 
llvm-svn: 19336
 2005-01-07 07:51:11 +00:00
Chris Lattner ca4ca5520b Allow the selection-dag based selector to be diabled with -disable-pattern-isel. 
For now, this is the default, as the current selector is missing some big pieces.
To enable the new selector, pass -disable-pattern-isel=false to llc or lli.
