Chris Lattner ad2cbf0e18 Fix a bug that caused a crash if a setcc had zero uses.

Chris Lattner 8d44b99844 Chris seems fond of #include <vector>. Fix these. Also convert use list in 
Value to a vector instead of a list.

Chris Lattner 87b3bf630b Split Target/Machine.h into three files:

TODO: Split out reg info stuff
llvm-svn: 567
 2001-09-14 06:08:03 +00:00
Chris Lattner 22a6a90511 Make a new llvm/Target #include directory. 
Move files from lib/CodeGen/TargetMachine to lib/Target
Move TargetData.h and TargetMachine.h to Target/{Data.h|Machine.h}
Prepare to split TargetMachine.h into several smaller files

 2001-09-14 05:34:53 +00:00
Chris Lattner f8464e4b8d Checkin changes to: 
1. Clean up the TargetMachine structure.  No more wierd pointers that have to
   be cast around and taken care of by the target.
2. Instruction Scheduling now takes the schedinfo as an argument.  The same
   should be done with the instinfo, it just isn't now.

Chris Lattner 0a823a062c This checkin represents some cleanup of the backend, implementing the following things: 
1. The TargetMachine structure is free to decide the process a particular target uses to generate code.
2. All of the gooee details of the sparc backend are now localized in the lib/CodeGen/TargetMAchine/Sparc directory.  The Sparc.h file that is globally visible is just a stub.
3. The Sparc.h file that esxists now will dissapear entirely someday when we have multiple backends chosen by a factory of some sort.

NOTE! The BBLiveVar.cpp file dependant on the Sparc backend, and is therefore not generic/portale to other backends.  This needs to be fixed.

WARNING: getOperand(x) where x >= getNumOperands() will now assert instead
of returning null!
