Jim Laskey a2b5235fac Give full control of subtarget features over to table generated code.

Chris Lattner ce9580fce4 Add nodes for CondCodeSDNode and setcc, and add a bunch of pattern fragments 
to make it easy to use them.  This lets you write patterns like:

(set PRRC:$rd, (setne GPRC:$rS, imm:$SH))

and stuff.

Nate Begeman 762bf809b5 Correctly Expand or Promote FP_TO_UINT based on the capabilities of the 
machine.  This allows us to generate great code for i32 FP_TO_UINT now on
targets with 64 bit extensions.

Andrew Lenharth c6072af580 Add several things. 
loads
branches
setcc
working calls
Global address
External addresses

now I can manage malloc calls.

Andrew Lenharth 5a990417f8 Well, the Constant matching pattern works. Can't say much about calls or globals yet.

Jim Laskey 13a19453d2 Add g3 back to the mix and reorder to irritate them anal folk. Actually, it's 
to group appropriately and provide cues to maintainers that the lists don't
need to be ordered.

 2005-10-22 08:04:24 +00:00
Chris Lattner c5d511c4d9 64-bit reg support should not be enabled by default, as support isn't complete.

 2005-10-21 22:15:43 +00:00
Chris Lattner e296949fbe Instead of aborting if not a case we can handle specially, break out and 
let the generic code handle it.  This fixes CodeGen/Generic/2005-10-21-longlonggtu.ll on ppc.

also, reindent this code

Nate Begeman fd0d55ec69 Match rotate. This does actually match the rotates in an rc5 cipher, but I 
haven't seen it fire on our testsuite.

Nate Begeman 4dd383120f Invert the TargetLowering flag that controls divide by consant expansion. 
Add a new flag to TargetLowering indicating if the target has really cheap
  signed division by powers of two, make ppc use it.  This will probably go
  away in the future.
Implement some more ISD::SDIV folds in the dag combiner
Remove now dead code in the x86 backend.
