Jeffrey Yasskin 9b43f33620 Change all self assignments X=X to (void)X, so that we can turn on a 
new gcc warning that complains on self-assignments and
self-initializations.

Chris Lattner 3e5fbd74ed rename MVT::Flag to MVT::Glue. "Flag" is a terrible name for 
something that just glues two nodes together, even if it is
sometimes used for flags.

Bruno Cardoso Lopes 03c0330176 Enable mips32 mul instruction. Patch by Akira Hatanaka <ahatanaka@mips.com> 
llvm-svn: 118864
 2010-11-12 00:38:32 +00:00
Chris Lattner 0e023ea02a fix a long standing wart: all the ComplexPattern's were being 
passed the root of the match, even though only a few patterns
actually needed this (one in X86, several in ARM [which should
be refactored anyway], and some in CellSPU that I don't feel 
like detangling).   Instead of requiring all ComplexPatterns to
take the dead root, have targets opt into getting the root by
putting SDNPWantRoot on the ComplexPattern.

Dan Gohman 21cea8ac2e Use const qualifiers with TargetLowering. This eliminates several 
const_casts, and it reinforces the design of the Target classes being
immutable.

SelectionDAGISel::IsLegalToFold is now a static member function, because
PIC16 uses it in an unconventional way. There is more room for API
cleanup here.

And PIC16's AsmPrinter no longer uses TargetLowering.

Chris Lattner f98f124a73 Sink InstructionSelect() out of each target into SDISel, and rename it 
DoInstructionSelection.  Inline "SelectRoot" into it from DAGISelHeader.
Sink some other stuff out of DAGISelHeader into SDISel.

Eliminate the various 'Indent' stuff from various targets, which dates
to when isel was recursive.

Chris Lattner b06015aa69 move target-independent opcodes out of TargetInstrInfo 
into TargetOpcodes.h.  #include the new TargetOpcodes.h
into MachineInstr.  Add new inline accessors (like isPHI())
to MachineInstr, and start using them throughout the 
codebase.

Bruno Cardoso Lopes aa8c429a53 MulOp is actually a Mips specific node, so do the match using Opcode. This fixes PR6192 
llvm-svn: 94977

Bruno Cardoso Lopes e1afaf5c22 Fix a bug introduced on r92564 where the name "Node" was already 
in use by Mips.

llvm-svn: 93897
 2010-01-19 19:57:07 +00:00
Bruno Cardoso Lopes 4f34432d09 On pic function calls some arguments were marked dead and 
the instruction to load those args removed. This fix PR6071

Bruno Cardoso Lopes c9818a77cb load f64 +0.0 in a cleaner way. This fix part of PR5445 
llvm-svn: 93876
 2010-01-19 12:53:04 +00:00
Dan Gohman ea6f91ff64 Change SelectCode's argument from SDValue to SDNode *, to make it more 
clear what information these functions are actually using.

This is also a micro-optimization, as passing a SDNode * around is
simpler than passing a { SDNode *, int } by value or reference.

Bruno Cardoso Lopes 2c6d498ccc Use endianess dependent offsets for load/store of doubles when 
using two swc/lwc instead of sdc/ldc.

llvm-svn: 89826
 2009-11-25 01:05:25 +00:00
Bruno Cardoso Lopes 4713b282ce - Add sugregister logic to handle f64=(f32,f32). 
- Support mips1 like load/store of doubles:

Instead of:
  sdc $f0, X($3)
Generate:
  swc $f0, X($3)
  swc $f1, X+4($3)

llvm-svn: 89322
 2009-11-19 06:06:13 +00:00
Bruno Cardoso Lopes 537e409c58 - Fix a small bug while handling target constant pools (one param was missing). 
- Add a smarter constant pool loading, instead of:

lui $2, %hi($CPI1_0)
addiu $2, $2, %lo($CPI1_0)
lwc1 $f0, 0($2)

Generate:

lui $2, %hi($CPI1_0)
lwc1 $f0, %lo($CPI1_0)($2)

VISIBILITY_HIDDEN removal.

llvm-svn: 85043
 2009-10-25 06:57:41 +00:00
Nick Lewycky 02d5f77d26 Remove VISIBILITY_HIDDEN from class/struct found inside anonymous namespaces. 
Chris claims we should never have visibility_hidden inside any .cpp file but
that's still not true even after this commit.

llvm-svn: 85042
 2009-10-25 06:33:48 +00:00
Dan Gohman 32f71d714b Rename getTargetNode to getMachineNode, for consistency with the 
naming scheme used in SelectionDAG, where there are multiple kinds
of "target" nodes, but "machine" nodes are nodes which represent
a MachineInstr.
