2009-07-03Replace std::iostreams with raw_ostream in TableGen.Daniel Dunbar
- Sorry, I can't help myself. - No intended functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74742 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-02Revert 72707 and 72709, for the moment.Dale Johannesen
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72712 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-01Make the implicit inputs and outputs of target-independentDale Johannesen
ADDC/ADDE use MVT::i1 (later, whatever it gets legalized to) instead of MVT::Flag. Remove CARRY_FALSE in favor of 0; adjust all target-independent code to use this format. Most targets will still produce a Flag-setting target-dependent version when selection is done. X86 is converted to use i32 instead, which means TableGen needs to produce different code in xxxGenDAGISel.inc. This keys off the new supportsHasI1 bit in xxxInstrInfo, currently set only for X86; in principle this is temporary and should go away when all other targets have been converted. All relevant X86 instruction patterns are modified to represent setting and using EFLAGS explicitly. The same can be done on other targets. The immediate behavior change is that an ADC/ADD pair are no longer tightly coupled in the X86 scheduler; they can be separated by instructions that don't clobber the flags (MOV). I will soon add some peephole optimizations based on using other instructions that set the flags to feed into ADC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72707 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-13Generalize getRegisterClassForRegister to handle registersDan Gohman
in multiple classes in the case that the classes are all in subset/superset relations. This function is used by the fast-isel emitter, which always wants the super-most set. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68957 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-20Factor the code for determining the target-specific instructionDan Gohman
namespace out of the isel emitters and into common code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55079 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-25Added MemOperands to Atomic operations since Atomics touches memory.Mon P Wang
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 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52706 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-06Wrap MVT::ValueType in a struct to get type safetyDuncan Sands
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). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52044 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-03Move instruction flag inference out of InstrInfoEmitter and intoDan Gohman
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49123 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-31Allow ComplexExpressions in InstrInfo.td files to be slightly more... ↵Christopher Lamb
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46606 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45822 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-10realize that instructions who match intrinsics that read memory read memory.Chris Lattner
Also, instructions with any nodes that are SDNPMayLoad also read memory. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45817 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-06Change the 'isStore' inferrer to look for 'SDNPMayStore' Chris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45654 91177308-0d34-0410-b5e6-96231b3b80d8
