* New testcase, neither should require a register-register copyChris Lattner2005-09-091-0/+26

| | | | llvm-svn: 23287
* Introduce two new concepts:Chris Lattner2005-09-091-11/+75
| | | | | | | | | | | | | | 1. Add support for defining Pattern's, which can match expressions when there is no instruction that directly implements something. Instructions usually implicitly define patterns. 2. Add support for defining SDNodeXForm's, which are node transformations. This seperates the concept of a node xform out from the existing predicate support. Using this new stuff, we add a few instruction patterns, one for testing, and two for OR/XOR by an arbitrary immediate. llvm-svn: 23286

* Implement a complete type inference system for dag patterns, based on theChris Lattner2005-09-082-13/+234
| | | | | | | | | | | | | | | constraints defined in the DAG node definitions in the .td files. This allows us to infer (and check!) the types for all nodes in the current ppc .td file. For example, instead of: Inst pattern EQV: (set GPRC:i32:$rT, (xor (xor GPRC:i32:$rA, GPRC:i32:$rB), (imm)<<Predicate_immAllOnes>>)) we now fully infer: Inst pattern EQV: (set:void GPRC:i32:$rT, (xor:i32 (xor:i32 GPRC:i32:$rA, GPRC:i32:$rB), (imm:i32)<<Predicate_immAllOnes>>)) from: (set GPRC:$rT, (not (xor GPRC:$rA, GPRC:$rB))) llvm-svn: 23284
