* memoize the assert resultsChris Lattner2005-09-261-2/+5
| | | | llvm-svn: 23457
* Emit the switch stmt cases in alphabetical order instead of pointer order,Chris Lattner2005-09-261-4/+19
| | | | | | which is not stable. llvm-svn: 23456
* implement a fixme: only select values once, even if used multiple times.Chris Lattner2005-09-261-5/+8

* Teach the DAG isel generator to emit code that creates nodes.Chris Lattner2005-09-242-18/+110
| | | | | | Fix a few corner cases parsing things like (i32 imm:$foo) llvm-svn: 23417
* Emit better code (no more copies for var references), and support DAG patternsChris Lattner2005-09-232-8/+25
| | | | | | (e.g. things like rotates). llvm-svn: 23416
* Fix a fixme by passing around SDOperand's instead of SDNode*'sChris Lattner2005-09-231-15/+14
| | | | llvm-svn: 23415
* Emit code that matches the incoming DAG pattern and checks predicates.Chris Lattner2005-09-232-4/+64
| | | | | | | | | This does not check that types match yet, but PPC only has one integer type ;-). This also doesn't have the code to build the resultant dag. llvm-svn: 23414

* teach the type inference code how to infer types for instructions and nodeChris Lattner2005-09-152-33/+66
| | | | | | | xforms. Run type inference on result patterns, so we always have fully typed results (and to catch errors in .td files). llvm-svn: 23369

* Verify that xform functions only occur in logical placesChris Lattner2005-09-141-5/+14
| | | | llvm-svn: 23363
* Promote xform fns to be explicit nodes in result patterns, and clean offChris Lattner2005-09-141-1/+15
| | | | | | predicates since they will have already matched at this point. llvm-svn: 23362
* start building the instruction dest pattern correctly. Change the xformChris Lattner2005-09-142-15/+27
| | | | | | | functions to preserve the Record for the xform instead of making it into a function name. llvm-svn: 23361

* 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
