Nate Begeman 569c439567 Get rid of code in the DAGCombiner that is duplicated in SelectionDAG.cpp 
Now all constant folding in the code generator is in one place.

Chris Lattner e2ee190821 Temporary work around for a libcall insertion bug: If a target doesn't 
support FSIN/FCOS nodes, do not lower sin/cos to them.

Jim Laskey 194a5268cb Added minimum Dwarf aranges. Cleaned up some section headers. Line number 
support now works in gdb.

is added.

Reid Spencer b4f9a6f110 For PR411: 
This patch is an incremental step towards supporting a flat symbol table.
It de-overloads the intrinsic functions by providing type-specific intrinsics
and arranging for automatically upgrading from the old overloaded name to
the new non-overloaded name. Specifically:
  llvm.isunordered -> llvm.isunordered.f32, llvm.isunordered.f64
  llvm.sqrt -> llvm.sqrt.f32, llvm.sqrt.f64
  llvm.ctpop -> llvm.ctpop.i8, llvm.ctpop.i16, llvm.ctpop.i32, llvm.ctpop.i64
  llvm.ctlz -> llvm.ctlz.i8, llvm.ctlz.i16, llvm.ctlz.i32, llvm.ctlz.i64
  llvm.cttz -> llvm.cttz.i8, llvm.cttz.i16, llvm.cttz.i32, llvm.cttz.i64
New code should not use the overloaded intrinsic names. Warnings will be
emitted if they are used.

Nate Begeman 2642a35f4c Expand case for 64b Legalize, even though no one should end up using this 
(itanium supports bswap natively, alpha should custom lower it using the
VAX floating point swapload, ha ha).

be subtracted from the stack pointer.
