Add a minor compile time win, no codegen change.

This gets rid of two gotos, which is always nice, and also adds some comments.

No functionality change, this is just a refactor.

Add support for addressing modes.

several bugs in inline asm expanded operands.

a single register number.  This fully implements promotion for inline asms,
expand is close but not quite right yet.

them to get ressurected, in which case, deleting the undead nodes is
unfriendly.

i64 before this code, so zero_ext doesn't work.

where we were doing exactly that which was causing failures on x86 and
alpha.

llvm-svn: 26284

exactly the API we wanted to call into.  This fixes the crash on crafty last
night.

Make more use of the new mask helpers in valuetypes.h
Combine (sra (srl x, c1), c1) -> sext_inreg if legal

and SUBE nodes that actually expose what's going on and allow for
significant simplifications in the targets.

llvm-svn: 26255

conversions to __floatdidf instead of __floatdisf on targets that support
f32 but not i64 (e.g. sparc).

llvm-svn: 26254

back.

llvm-svn: 26242

and ComputeMaskedBits to match the new improved versions in instcombine.
Tested against all of multisource/benchmarks on ppc.

llvm-svn: 26238

We do not want to emit "Loop: ... brcond Out; br Loop", as it adds an extra
instruction in the loop.  Instead, invert the condition and emit
"Loop: ... br!cond Loop; br Out.

Generalize the fix by moving it from PPCDAGToDAGISel to SelectionDAGLowering.
