* Factor the code for determining the target-specific instructionDan Gohman2008-08-201-0/+4
| | | | | | namespace out of the isel emitters and into common code. llvm-svn: 55079
* Added MemOperands to Atomic operations since Atomics touches memory.Mon P Wang2008-06-251-1/+4
| | | | | | | | Added abstract class MemSDNode for any Node that have an associated MemOperand Changed atomic.lcs => atomic.cmp.swap, atomic.las => atomic.load.add, and atomic.lss => atomic.load.sub llvm-svn: 52706
* Wrap MVT::ValueType in a struct to get type safetyDuncan Sands2008-06-061-12/+12
| | | | | | | | | | | | | | | | and better control the abstraction. Rename the type to MVT. To update out-of-tree patches, the main thing to do is to rename MVT::ValueType to MVT, and rewrite expressions like MVT::getSizeInBits(VT) in the form VT.getSizeInBits(). Use VT.getSimpleVT() to extract a MVT::SimpleValueType for use in switch statements (you will get an assert failure if VT is an extended value type - these shouldn't exist after type legalization). This results in a small speedup of codegen and no new testsuite failures (x86-64 linux). llvm-svn: 52044
* Move instruction flag inference out of InstrInfoEmitter and intoDan Gohman2008-04-031-0/+4
| | | | | | | | | | | | CodeGenDAGPatterns, where it can be used in other tablegen backends. This allows the inference to be done for DAGISelEmitter so that it gets accurate mayLoad/mayStore/isSimpleLoad flags. This brings MemOperand functionality back to where it was before 48329. However, it doesn't solve the problem of anonymous patterns which expand to code that does loads or stores. llvm-svn: 49123
* Allow ComplexExpressions in InstrInfo.td files to be slightly more... ↵Christopher Lamb2008-01-311-2/+6
| | | | | | | | | | complex! ComplexExpressions can now have attributes which affect how TableGen interprets the pattern when generating matchin code. The first (and currently, only) attribute causes the immediate parent node of the ComplexPattern operand to be passed into the matching code rather than the node at the root of the entire DAG containing the pattern. llvm-svn: 46606
* start inferring 'no side effects'.Chris Lattner2008-01-101-1/+2
| | | | llvm-svn: 45822
* realize that instructions who match intrinsics that read memory read memory.Chris Lattner2008-01-101-0/+1
| | | | | | Also, instructions with any nodes that are SDNPMayLoad also read memory. llvm-svn: 45817
* Change the 'isStore' inferrer to look for 'SDNPMayStore' Chris Lattner2008-01-061-2/+9
| | | | | | | | | | | instead of "ISD::STORE". This allows us to mark target-specific dag nodes as storing (such as ppc byteswap stores). This allows us to remove more explicit isStore flags from the .td files. Finally, add a warning for when a .td file contains an explicit isStore and tblgen is able to infer it. llvm-svn: 45654
* change getQualifiedName to be a global function.Chris Lattner2008-01-051-1/+4
| | | | | | | | Split the pattern parsing code out from the dag isel emitter into it's own file. No functionality change. llvm-svn: 45632
* remove attributions from utils.Chris Lattner2007-12-291-2/+2

* Eliminate an unused parameter.Dan Gohman2007-07-131-1/+1

* Remove the operator<< for MVT::ValueType in preparation for MVT::ValueTypeDan Gohman2007-06-041-1/+0
| | | | | | | being changed from an enum to an integer type, which can't have a custom operator<< overload. llvm-svn: 37412

| | | | | | * Renamed MatchingNodes to RootNodes. llvm-svn: 24636
* Added support for ComplexPattern. These are patterns that require C++ patternEvan Cheng2005-12-081-0/+17
| | | | | | | matching code that is not currently auto-generated by tblgen, e.g. X86 addressing mode. Selection routines for complex patterns can return multiple operands, e.g. X86 addressing mode returns 4. llvm-svn: 24634
