Evan Cheng e8b5180044 Now generating perfect (I think) code for "vector set" with a single non-zero 
scalar value.

e.g.
        _mm_set_epi32(0, a, 0, 0);
==>
	movd 4(%esp), %xmm0
	pshufd $69, %xmm0, %xmm0

        _mm_set_epi8(0, 0, 0, 0, 0, a, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0);
==>
	movzbw 4(%esp), %ax
	movzwl %ax, %eax
	pxor %xmm0, %xmm0
	pinsrw $5, %eax, %xmm0

Chris Lattner cc47ab3305 Fix a really subtle and obnoxious memory bug that caused issues with an 
llvm-gcc4 boostrap.  Whenever a node is deleted by the dag combiner, it
*must* be returned by the visit function, or the dag combiner will not
know that the node has been processed (and will, e.g., send it to the
target dag combine xforms).

Reid Spencer 5e6f97b7c9 Don't require the "dot" program if -flat option is given, and don't produce 
any of the fancy graphs or other output. Just produce the flat, makefile
style output on stdout.

Reid Spencer 5952201b67 Several Changes To Support Building llvm-config: 
1. If Perl is not available, don't run Perl dependent targets.
2. Check in FinalLibDeps.txt for build environments that can't build it
   because there's no Perl processor.
3. Ensure that FinalLibDeps.txt depends on LibDeps.txt so it is
   automatically regenerated.
4. Support objdir != srcdir building.

 2006-04-20 09:01:54 +00:00
Evan Cheng 60f0b8998e - Added support to turn "vector clear elements", e.g. pand V, <-1, -1, 0, -1> 
to a vector shuffle.
- VECTOR_SHUFFLE lowering change in preparation for more efficient codegen
of vector shuffle with zero (or any splat) vector.

llvm-svn: 27875
 2006-04-20 08:58:49 +00:00
Evan Cheng a320abc494 Turn a VAND into a VECTOR_SHUFFLE is applicable. 
DAG combiner can turn a VAND V, <-1, 0, -1, -1>, i.e. vector clear elements,
into a vector shuffle with a zero vector. It only does so when TLI tells it
the xform is profitable.
