* Add VirtRegMap::rewrite() and use it in the new register allocators.Jakob Stoklund Olesen2011-02-184-6/+81
| | | | | | | | | | The rewriter works almost identically to -rewriter=trivial, except it also eliminates any identity copies. This makes the new register allocators independent of VirtRegRewriter.cpp which will be going away at the same time as RegAllocLinearScan. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125967 91177308-0d34-0410-b5e6-96231b3b80d8
* Add FixedLenDecoderEmitter, the skeleton of a new disassembler emitter for ↵Owen Anderson2011-02-185-98/+1534
| | | | | | | | | | | | | | fixed-length instruction encodings. A major part of its (eventual) goal is to support a much cleaner separation between disassembly callbacks provided by the target and the disassembler emitter itself, i.e. not requiring hardcoding of knowledge in tblgen like the existing disassembly emitters do. The hope is that some day this will allow us to replace the existing non-Thumb ARM disassembler and remove some of the hacks the old one introduced to tblgen. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125966 91177308-0d34-0410-b5e6-96231b3b80d8
