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

Jim Laskey 53ad110490 Add attribute name and type to SubtargetFeatures.

Chris Lattner 38a1b00a0f fold nested and's early to avoid inefficiencies in MaskedValueIsZero. This 
fixes a very slow compile in PR639.

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.

Nate Begeman d8f2a1a0f3 Allow custom lowered FP_TO_SINT ops in the check for whether a larger 
FP_TO_SINT is preferred to a larger FP_TO_UINT.  This seems to be begging
for a TLI.isOperationCustom() helper function.

Chris Lattner 46705b2f2d Handle allocations that, even after removing dead uses, still have more than 
one use (but one is a cast).  This handles the very common case of:

 X = alloc [n x byte]
 Y = cast X to somethingbetter
 seteq X, null

In order to avoid infinite looping when there are multiple casts, we only
allow this if the xform is strictly increasing the alignment of the
allocation.

llvm-svn: 23961
 2005-10-24 06:35:18 +00:00
Chris Lattner 355ecc09f8 Fix a bug where we would 'promote' an allocation from one type to another 
where the second has less alignment required.  If we had explicit alignment
support in the IR, we could handle this case, but we can't until we do.

llvm-svn: 23960
 2005-10-24 06:26:18 +00:00
Chris Lattner ac87beb03a Before promoting a malloc type, remove dead uses. This makes instcombine 
more effective at promoting these allocations, catching them earlier in the
compile process.

Chris Lattner 476b8ddd55 Alkis agrees that that iterative scan allocator isn't going to be worked on 
in the future, remove it.
