Chris Lattner 17cc9edd33 Add a case we were missing that was causing us to fail CodeGen/PowerPC/rlwinm.ll:test3

Nate Begeman c0896117d3 Remove some dead code now that the dag combiner exists.

Chris Lattner d869bec4fe Remove some dead code: the ORI/ORIS cases are autogen'd. This makes 
SelectIntImmediateExpr dead.

Chris Lattner 6b22d2554a Implement the last major missing piece in the DAG isel generator: when emitting 
a pattern match, make sure to emit the (minimal number of) type checks that
verify the pattern matches this specific instruction.  This allows FMA32
patterns to not match double expressions for example.

Chris Lattner b986f471be Use getExtLoad here instead of getNode, as extloads produce two values. This 
fixes a legalize failure on SPASS for itanium.

Nate Begeman 9d7008b08d Properly split f32 and f64 into separate register classes for scalar sse fp 
fixing a bunch of nasty hackery

llvm-svn: 23735
 2005-10-14 22:06:00 +00:00
Nate Begeman c41e1be2e8 Remove an unnecsesary file. PPC32 and PPC64 share architected registers. 
We will decide with subtarget support whether we ever use an i64 register
class.

Chris Lattner c4db8f4163 Now that we have int/fp lattice values, implement the SDTCisOpSmallerThanOp 
type constraint.  This lets tblgen realize that it doesn't need any dynamic
type checks for fextend/fround on PPC (and many other targets), because there
are only two fp types.

llvm-svn: 23730
 2005-10-14 06:25:00 +00:00
Chris Lattner ecaf56b21a Fairly serious rework of the typing code to add new int/fp lattice values. 
Overall, no functionality change yet though.

Chris Lattner 6e83cbf7f3 add a new SDTCisOpSmallerThanOp type constraint, and implement fround/fextend in terms of it 
llvm-svn: 23726
 2005-10-14 04:55:10 +00:00
Chris Lattner 4892df38f3 Add basic support for recognizing a new SDTCisOpSmallerThanOp type constraint 
llvm-svn: 23725
 2005-10-14 04:53:53 +00:00
Chris Lattner 7b0275ba8c Implement a couple of new (important) features. 
1. If an operation has to be int or fp and the target only supports one
   int or fp type, relize that the op has to have that type.
2. If a target has operations on multiple types, do not emit matching code
   for patterns involving those operators, since we do not emit the code to
   check for them yet.  This prevents PPC from generating FP ops currently.

Also move some code around into more logical places.

Nate Begeman 6e673b24d3 fold sext_in_reg, sext_in_reg where both have the same VT. This was 
popping up in Fourinarow.

Nate Begeman d59e5a7abb Relax the checking on zextload generation a bit, since as sabre pointed out 
you could be AND'ing with the result of a shift that shifts out all the
bits you care about, in addition to a constant.

Also, move over an add/sub_parts fold from legalize to the dag combiner,
where it works for things other than constants.  Woot!

Chris Lattner 258521d7ea When ExpandOp'ing a [SZ]EXTLOAD, make sure to remember that the chain 
is also legal.  Add support for ExpandOp'ing raw EXTLOADs too.

the remainder of the failures introduced by my patch last night.

Nate Begeman c3a89c5259 Add support to Legalize for expanding i64 sextload/zextload into hi and lo 
parts. This should fix the crafty and signed long long unit test failure
on x86 last night.

Jim Laskey 5d7a50ac44 Inhibit instructions from being pushed before function calls. This will 
minimize unnecessary spilling.

DSA.
