Chris Lattner 4a744e5c9d Fix some broken logic that would cause us to codegen {2147483647,2147483647,2147483647,2147483647} as 'vspltisb v0, -1'.

Chris Lattner 4ea52cac01 Do not create ZEXTLOAD's unless we are before legalize or the operation is 
legal.

Chris Lattner d5ed3789dd New testcase 
llvm-svn: 27401
 2006-04-04 17:38:31 +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.

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.

Reid Spencer 11dd4b9d9c For PR722: 
Change the check for llvm-gcc from using LLVMGCCDIR to LLVMGCC. This checks
for the actual tool rather than the directory in which the tool resides. In
the case of this bug, it is possible that the directory exists but that the
tools in that directory do not. This fix should avoid the makefile from
erroneously proceeding without the actual tools being available.
