| 2012-02-03 | The type-legalizer often scalarizes code. One of the common patterns is ↵ | Nadav Rotem | |
| extract-and-truncate. In this patch we optimize this pattern and convert the sequence into extract op of a narrow type. This allows the BUILD_VECTOR dag optimizations to construct efficient shuffle operations in many cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149692 91177308-0d34-0410-b5e6-96231b3b80d8 | |||
| 2011-12-08 | Fix a bug in the integer-promotion of bitcast operations on vector types. | Nadav Rotem | |
| We must not issue a bitcast operation for integer-promotion of vector types, because the location of the values in the vector may be different. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146150 91177308-0d34-0410-b5e6-96231b3b80d8 | |||
