2005-09-14start building the instruction dest pattern correctly. Change the xformChris Lattner
functions to preserve the Record for the xform instead of making it into a function name. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23361 91177308-0d34-0410-b5e6-96231b3b80d8

2005-09-13Emit code suitable for emission into the ISel class, allowing us to use/defineChris Lattner
methods. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23340 91177308-0d34-0410-b5e6-96231b3b80d8

2005-09-09use new accessors to simplify code. Add checking to make sure top-level instrChris Lattner
definitions are void git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23288 91177308-0d34-0410-b5e6-96231b3b80d8
2005-09-08Fix incorrect commentChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23285 91177308-0d34-0410-b5e6-96231b3b80d8
2005-09-08Implement a complete type inference system for dag patterns, based on theChris Lattner
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))) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23284 91177308-0d34-0410-b5e6-96231b3b80d8

2005-09-08Keep names even when inlining. This allows us to realize that ADDI is:Chris Lattner
(set GPRC:i32:$rD, (add GPRC:i32:$rA, (imm)<<Predicate_immSExt16>>:$imm)) not: (set GPRC:i32:$rD, (add GPRC:i32:$rA, (imm)<<Predicate_immSExt16>>)) (we keep the ":$imm") git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23269 91177308-0d34-0410-b5e6-96231b3b80d8
2005-09-07Initial cut of the dag isel generator. This is still very much a work inChris Lattner
progress. It correctly parses instructions and pattern fragments and glues together pattern fragments into instructions. The only code it generates currently is some boilerplate code for things like the EntryNode. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23261 91177308-0d34-0410-b5e6-96231b3b80d8
