for any VT.

Chris Lattner 35d20a4c00 remove now-dead code, the legalizer takes care of this for us 
llvm-svn: 25776
 2006-01-29 06:45:31 +00:00
Chris Lattner 132177e103 The FP stack doesn't support UNDEF, ask the legalizer to legalize it 
instead of lying and saying we have it.

Chris Lattner 2f292789dc Allow custom expansion of ConstantVec nodes. PPC will use this in the future. 
llvm-svn: 25774

 2006-01-29 06:32:58 +00:00
Chris Lattner 758b0ac54b Legalize ConstantFP into TargetConstantFP when the target allows. Implement 
custom expansion of ConstantFP nodes.

llvm-svn: 25772
 2006-01-29 06:26:56 +00:00
Chris Lattner 61c9a8e942 Targets all now request ConstantFP to be legalized into TargetConstantFP. 
'fpimm' in .td files is now TargetConstantFP.

Chris Lattner b5f0ba6051 Update alpha to reflect recent constantfp legalize changes. It's not clear 
why all this code isn't autogenerated. :(

llvm-svn: 25770
 2006-01-29 06:25:22 +00:00
Chris Lattner 9b60714b2a Make ConstantFP legalize into TargetConstantFP like other leaf nodes do. Allow 
targets to register custom legalizers for ConstantFP in case there isn't a
fixed list of constants that can be generated.  On some architectures (ia64?)
all fp immediates are legal.

Andrew Lenharth 1af077c0c7 it is nice not to chop off bits for those blessed with lots of bits 
llvm-svn: 25766
 2006-01-29 05:22:37 +00:00

Chris Lattner 0e352963fd Emit series of conditionals with &&, emitting stuff like this: 
if (N1.getOpcode() == ISD::LOAD &&
        N1.hasOneUse() &&
        !CodeGenMap.count(N1.getValue(0)) &&
        !CodeGenMap.count(N1.getValue(1))) {

instead of this:

    if (N1.getOpcode() == ISD::LOAD) {
      if (N1.hasOneUse()) {
        if (!CodeGenMap.count(N1.getValue(0))) {
          if (!CodeGenMap.count(N1.getValue(1))) {

Chris Lattner 7c0149d1d6 Factor matching code that is common between patterns. This works around 
GCC not jump-threading across this common code, and produces far nicer
output.

Chris Lattner d3a63de91e Split out code generation from analysis from emission 
llvm-svn: 25759
 2006-01-29 02:57:39 +00:00
Chris Lattner afe9baeb69 move some code around, no change in the generated code 
llvm-svn: 25758
 2006-01-29 02:43:35 +00:00
Chris Lattner 5255c6c627 now that we have control over emission of the code, emit the code using nested 
"if" statements (indenting it appropriately, of course) instead of using goto's.

This inverts the logic for all of the if statements, which makes things simpler
to understand in addition to making the generated code easier to read.

llvm-svn: 25757
 2006-01-28 20:43:52 +00:00
Chris Lattner 4c4da201bf Change PatternCodeEmitter to emit code into a buffer instead of emitting it 
directly to the output file.  This makes things simple because the code doesn't
have to worry about indentation or the case when there is no goto.  It also
allows us to indent the code better without touching everything :)

are not skewed out of view.
