Chris Lattner e769482fd3 Pull all of the scheduling related stuff out of Sparc.cpp into it's own file 
llvm-svn: 1668
 2002-02-04 00:39:14 +00:00
Chris Lattner 36aa542ef0 Split RegisterAllocation stuff OUT of Sparc.cpp into a well defined pass 
that has a very minimal interface (like it should have).

 2002-02-04 00:33:08 +00:00
Chris Lattner 64593c51bb Move a ton of tables out of SparcInternals.h and move them to Sparc.cpp. 
Eventually they will probably get moved again, but at least now they aren't
having to be compiled by 7 different .cpp files...
