* Add two new record types to the blockinfo block:Chris Lattner2009-04-264-14/+79
| | | | | | | | | | BLOCKNAME and SETRECORDNAME. This allows a bitcode file to be self describing with pretty names for records and blocks in addition to numbers. This enhances llvm-bcanalyzer to use this to print prettily. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@70165 91177308-0d34-0410-b5e6-96231b3b80d8

* PR2957Nate Begeman2009-04-2425-2157/+1610
| | | | | | | | | | | | | | | ISD::VECTOR_SHUFFLE now stores an array of integers representing the shuffle mask internal to the node, rather than taking a BUILD_VECTOR of ConstantSDNodes as the shuffle mask. A value of -1 represents UNDEF. In addition to eliminating the creation of illegal BUILD_VECTORS just to represent shuffle masks, we are better about canonicalizing the shuffle mask, resulting in substantially better code for some classes of shuffles. A clean up of x86 shuffle code, and some canonicalizing in DAGCombiner is next. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69952 91177308-0d34-0410-b5e6-96231b3b80d8
