features autodetected.  This fixes PR1010 and Regression/CodeGen/X86/xmm-r64.ll

Chris Lattner 539df43e4b setOperand should not zap the operand list or add implicit operands to an
instruction.  Doing so breaks the FP stackifier, the alpha branch selector
the sparc fpmover.

Reid Spencer d9436b6837 For PR950:
First in a series of patches to convert SetCondInst into ICmpInst and
FCmpInst using only two opcodes and having the instructions contain their
predicate value. Nothing uses these classes yet. More patches to follow.

Reid Spencer 9f4448a26e For PR950:
Retain the signedness of the old integer types in a new TypeInfo structure
so that it can be used in the grammar to implement auto-upgrade of things
that depended on signedness of types. This doesn't implement any new
functionality in the AsmParser, its just plumbing for future changes.

Chris Lattner ea017f66f7 Don't transform in another bad case: if the block is empty, it should be
simplified before we do this xform so that our cost model is accurate.

Chris Lattner 47ce26158f Minor code layout tweak: if we have something like this:
if (cond) goto BB2
BB1:
    ...
    return;
BB2:
   ...

Move BB1 to the end of the function so that the code falls through in the
non-return case.  This has the effect of moving assert (and other no-return
call) bodies and return blocks out of loops.

Chris Lattner 95adf8f1da Do not convert massive blocks on phi nodes into select statements. Instead
only do these transformations if there are a small number of phi's.
This speeds up Ptrdist/ks from 2.35s to 2.19s on my mac pro.

Reid Spencer 2ca613bcad This is a utility for preparing patches against LLVM. It runs cvs diff with
the correct options, places the patch content in order that makes sense for
review, and filters cruft out of the patch (like diffs in *.cvs files). It
produces both a NAME.patch.raw (unfiltered) and NAME.patch (filtered) file.

Chris Lattner 2cca385fbb on ppc64, float arguments take 8-byte stack slots not 4-byte stack slots.

Chris Lattner 542dfd5510 Rewrite the branch selector to be correct in the face of large functions.
The algorithm it used before wasn't 100% correct, we now use an iterative
expansion model.  This fixes assembler errors when compiling 403.gcc with
tail merging enabled.

Change the way the branch selector works overall: Now, the isel generates
PPC::BCC instructions (as it used to) directly, and these BCC instructions
are emitted to the output or jitted directly if branches don't need
expansion.  Only if branches need expansion are instructions rewritten
and created.  This should make branch select faster, and eliminates the
Bxx instructions from the .td file.

Chris Lattner be9377a1e3 convert PPC::BCC to use the 'pred' operand instead of separate predicate
value and CR reg #.  This requires swapping the order of these everywhere
that touches BCC and requires us to write custom matching logic for
PPCcondbranch :(

Evan Cheng 9e8093ae20 For unsigned 8-bit division. Use movzbw to set the lower 8 bits of AX while
clearing the upper 8-bits instead of issuing two instructions. This also
eliminates the need to target the AH register which can be problematic on
x86-64.
