2010-03-01Fix PR2590 by making PatternSortingPredicate actually be Chris Lattner
ordered correctly. Previously it would get in trouble when two patterns were too similar and give them nondet ordering. We force this by using the record ID order as a fallback.

2010-02-28Generalize my hack to use SDNodeInfo to find out when aChris Lattner

2009-08-29PR4795: Remove EEVT::isFP, isInt and isVec types used by TableGen's typeBob Wilson
inferencing. As far as I can tell, these are equivalent to the existing MVT::fAny, iAny and vAny types, and having both of them makes it harder to reason about and modify the type inferencing code. The specific problem in PR4795 occurs when updating a vAny type to be fAny or iAny, or vice versa. Both iAny and fAny include vector types -- they intersect with the set of types represented by vAny. When merging them, choose fAny/iAny to represent the intersection. This is not perfect, since fAny/iAny also include scalar types, but it is good enough for TableGen's type inferencing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80423 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-23Fix non-determinism in DAGISel emitter.Daniel Dunbar
- This manifested as non-determinism in the .inc output in rare cases (when two distinct patterns ended up being equivalent, which is rather rare). That meant the pattern matching was non-deterministic, which could eventually mean the code generator selected different instructions based on the arch. - It's probably worth making the DAGISel ensure a total ordering (or force the user to), but the simple fix here is to totally order the Record* maps based on a unique ID. - PR4672, PR4711.

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

2009-04-13Add a new TargetInstrInfo MachineInstr opcode, COPY_TO_SUBCLASS.Dan Gohman
This will be used to replace things like X86's MOV32to32_. Enhance ScheduleDAGSDNodesEmit to be more flexible and robust in the presense of subregister superclasses and subclasses. It can now cope with the definition of a virtual register being in a subclass of a use. Re-introduce the code for recording register superreg classes and subreg classes. This is needed because when subreg extracts and inserts get coalesced away, the virtual registers are left in the correct subclass. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68961 91177308-0d34-0410-b5e6-96231b3b80d8
