Dynamic, Initial Exec and Local Exec TLS models.

Patch by Sasa Stankovic

llvm-svn: 132322

Need this to prevent emitting illegal conditional move instructions. 

llvm-svn: 132240

llvm-svn: 129612

Fix lines that have incorrect indentation or exceed 80 columns. There is no change in functionality.

llvm-svn: 129606

Move transformation of JmpLink and related nodes done during instruction selection to Legalize phase.

llvm-svn: 128751

llvm-svn: 128750

Remove redundant code. There are assignments to variables Base and Offset right after the code that is removed.

new gcc warning that complains on self-assignments and
self-initializations.

sometimes used for flags.

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.

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.

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.

to MachineInstr, and start using them throughout the 
codebase.

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.

using two swc/lwc instead of sdc/ldc.

llvm-svn: 89826

- 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

- 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

Chris claims we should never have visibility_hidden inside any .cpp file but
that's still not true even after this commit.

naming scheme used in SelectionDAG, where there are multiple kinds
of "target" nodes, but "machine" nodes are nodes which represent
a MachineInstr.

llvm-svn: 82790

Add MO flags to simplify the printing of relocations.
Remove the support for printing large code model relocs (which
aren't supported anyway).
