* Some platforms use the same name for 32-bit and 64-bit registers (likeBill Wendling2008-02-241-0/+7
| | | | | | | | | | %r3 on PPC) in their ASM files. However, it's hard for humans to read during debugging. Adding a new field to the register data that lets you specify a different name to be printed than the one that goes into the ASM file -- %x3 instead of %r3, for instance. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47534 91177308-0d34-0410-b5e6-96231b3b80d8
* Merge current work back to tree to minimize diffs and drift. Major highlightsScott Michel2008-02-231-2/+13
| | | | | | | | | | | | | | | for CellSPU modifications: - SPUInstrInfo.td refactoring: "multiclass" really is _your_ friend. - Other improvements based on refactoring effort in SPUISelLowering.cpp, esp. in SPUISelLowering::PerformDAGCombine(), where zero amount shifts and rotates are now eliminiated, other scalar-to-vector-to-scalar silliness is also eliminated. - 64-bit operations are being implemented, _muldi3.c gcc runtime now compiles and generates the right code. More work still needs to be done. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47532 91177308-0d34-0410-b5e6-96231b3b80d8
