Nate Begeman 3f9c17906f Disable switch lowering for targets based on the selection dag isel, 
letting the code generator handle them directly.

Evan Cheng 78e3d565af INSERT_VECTOR_ELT lowering bug: 
store vector to $esp
  store element to $esp + sizeof(VT) * index
  load  vector from $esp
The bug is VT is the type of the vector element, not the type of the vector!

llvm-svn: 27491
 2006-04-07 16:34:46 +00:00
Chris Lattner 92b1a57010 We have an assertion that checks that we do not encode null values into the 
.bc file if they are supposed to be implicit.  This is cool, except that it
checked *after* constant expr folding: improving constant expr folding could
cause the .bc reader to assert out on old .bc files.  Move the check so that
it checks all simple constants, but no constantexprs.

Evan Cheng c995b45f67 - movlp{s|d} and movhp{s|d} support. 
- Normalize shuffle nodes so result vector lower half elements come from the
  first vector, the rest come from the second vector. (Except for the
  exceptions :-).
- Other minor fixes.

Chris Lattner e79d249c29 Lower vperm(x,y, mask) -> shuffle(x,y,mask) if mask is constant. This allows 
us to compile oh-so-realistic stuff like this:

 vec_vperm(A, B, (vector unsigned char){14});

to:
        vspltb v0, v0, 14

instead of:

        vspltisb v0, 14
        vperm v0, v2, v1, v0

Chris Lattner 1d33819194 Support pattern matching vsldoi(x,y) and vsldoi(x,x), which allows the f.e. to

Evan Cheng f3b52c84ea Handle canonical form of e.g. 
vector_shuffle v1, v1, <0, 4, 1, 5, 2, 6, 3, 7>

This is turned into
vector_shuffle v1, <undef>, <0, 0, 1, 1, 2, 2, 3, 3>

It would match a {p}unpckl on x86.

legal.

llvm-svn: 27402
 2006-04-04 17:39:18 +00:00
Chris Lattner 95c7adc7cb Ask legalize to promote all vector shuffles to be v16i8 instead of having to 
handle all 4 PPC vector types.   This simplifies the matching code and allows
us to eliminate a bunch of patterns.  This also adds cases we were missing,
such as CodeGen/PowerPC/vec_splat.ll:splat_h.

llvm-svn: 27400
 2006-04-04 17:25:31 +00:00
Chris Lattner 6be79823e7 * Add supprot for SCALAR_TO_VECTOR operations where the input needs to be 
promoted/expanded (e.g. SCALAR_TO_VECTOR from i8/i16 on PPC).
* Add support for targets to request that VECTOR_SHUFFLE nodes be promoted
  to a canonical type, for example, we only want v16i8 shuffles on PPC.
* Move isShuffleLegal out of TLI into Legalize.
* Teach isShuffleLegal to allow shuffles that need to be promoted.
