2008-03-10Give TargetLowering::getSetCCResultType() a parameter so that ISD::SETCC'sScott Michel
return ValueType can depend its operands' ValueType. This is a cosmetic change, no functionality impacted. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48145 91177308-0d34-0410-b5e6-96231b3b80d8

2008-02-27Convert SimplifyDemandedMask and ShrinkDemandedConstant to use APInt.Dan Gohman
Change several cases in SimplifyDemandedMask that don't ever do any simplifying to reuse the logic in ComputeMaskedBits instead of duplicating it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47648 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-26Change "Name" to "AsmName" in the target register info. Gee, a refactoring toolBill Wendling

2008-02-25Convert MaskedValueIsZero and all its users to use APInt. Also addDan Gohman
a SignBitIsZero function to simplify a common use case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47561 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-14In TargetLowering::LowerCallTo, don't assert thatDuncan Sands
the return value is zero-extended if it isn't sign-extended. It may also be any-extended. Also, if a floating point value was returned in a larger floating point type, pass 1 as the second operand to FP_ROUND, which tells it that all the precision is in the original type. I think this is right but I could be wrong. Finally, when doing libcalls, set isZExt on a parameter if it is "unsigned". Currently isSExt is set when signed, and nothing is set otherwise. This should be right for all calls to standard library routines. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47122 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-14Change how FP immediates are handled. Nate Begeman
1) ConstantFP is now expand by default 2) ConstantFP is not turned into TargetConstantFP during Legalize if it is legal. This allows ConstantFP to be handled like Constant, allowing for targets that can encode FP immediates as MachineOperands. As a bonus, fix up Itanium FP constants, which now correctly match, and match more constants! Hooray. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47121 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-13Simplify some logic in ComputeMaskedBits. And change ComputeMaskedBitsDan Gohman
to pass the mask APInt by value, not by reference. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47096 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-13Convert SelectionDAG::ComputeMaskedBits to use APInt instead of uint64_t.Dan Gohman
Add an overload that supports the uint64_t interface for use by clients that haven't been updated yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47039 91177308-0d34-0410-b5e6-96231b3b80d8

2008-01-30Factor the addressing mode and the load/store VT out of LoadSDNodeDan Gohman
and StoreSDNode into their common base class LSBaseSDNode. Member functions getLoadedVT and getStoredVT are replaced with the common getMemoryVT to simplify code that will handle both loads and stores. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46538 91177308-0d34-0410-b5e6-96231b3b80d8

2008-01-18remove extraneous &'s.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46171 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-17This commit changes:Chris Lattner
1. Legalize now always promotes truncstore of i1 to i8. 2. Remove patterns and gunk related to truncstore i1 from targets. 3. Rename the StoreXAction stuff to TruncStoreAction in TLI. 4. Make the TLI TruncStoreAction table a 2d table to handle from/to conversions. 5. Mark a wide variety of invalid truncstores as such in various targets, e.g. X86 currently doesn't support truncstore of any of its integer types. 6. Add legalize support for truncstores with invalid value input types. 7. Add a dag combine transform to turn store(truncate) into truncstore when safe. The later allows us to compile CodeGen/X86/storetrunc-fp.ll to: _foo: fldt 20(%esp) fldt 4(%esp) faddp %st(1) movl 36(%esp), %eax fstps (%eax) ret instead of: _foo: subl $4, %esp fldt 24(%esp) fldt 8(%esp) faddp %st(1) fstps (%esp) movl 40(%esp), %eax movss (%esp), %xmm0 movss %xmm0, (%eax) addl $4, %esp ret git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46140 91177308-0d34-0410-b5e6-96231b3b80d8

2008-01-10Output sinl for a long double FSIN node, not sin.Duncan Sands
Likewise fix up a bunch of other libcalls. While there I remove NEG_F32 and NEG_F64 since they are not used anywhere. This fixes 9 Ada ACATS failures. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45833 91177308-0d34-0410-b5e6-96231b3b80d8

2007-12-29Fold comparisons against a constant nan, and optimize ORD/UNORD Chris Lattner
comparisons with a constant. This allows us to compile isnan to: _foo: fcmpu cr7, f1, f1 mfcr r2 rlwinm r3, r2, 0, 31, 31 blr instead of: LCPI1_0: ; float .space 4 _foo: lis r2, ha16(LCPI1_0) lfs f0, lo16(LCPI1_0)(r2) fcmpu cr7, f1, f0 mfcr r2 rlwinm r3, r2, 0, 31, 31 blr git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45405 91177308-0d34-0410-b5e6-96231b3b80d8

2007-10-08Migrate X86 and ARM from using X86ISD::{,I}DIV and ARMISD::MULHILO{U,S} toDan Gohman
use ISD::{S,U}DIVREM and ISD::{S,U}MUL_HIO. Move the lowering code associated with these operators into target-independent in LegalizeDAG.cpp and TargetLowering.cpp. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42762 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-05First round of ppc long double. call/return andDale Johannesen
basic arithmetic works. Rename RTLIB long double functions to distinguish different flavors of long double; the lib functions have different names, alas. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42644 91177308-0d34-0410-b5e6-96231b3b80d8

2007-09-25Move the setOperationAction(ISD::DEBUG_LOC, MVT::Other, Expand) andDan Gohman
the check to see if the assembler supports .loc from X86TargetLowering into the superclass TargetLowering. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42297 91177308-0d34-0410-b5e6-96231b3b80d8

2007-09-07Add lengthof and endof templates that hide a lot of sizeof computations.Owen Anderson
Patch by Sterling Stein! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41758 91177308-0d34-0410-b5e6-96231b3b80d8
2007-08-25rename isOperandValidForConstraint to LowerAsmOperandForConstraint, Chris Lattner
changing the interface to allow for future changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41384 91177308-0d34-0410-b5e6-96231b3b80d8
2007-08-09long double 9 of N. This finishes up the X86-32 bitsDale Johannesen
(constants are still not handled). Adds ConvertActions to control fp-to-fp conversions (these are currently defaulted for all other targets, so no changes there). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@40958 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-09Initialize the IndexedModeActions array with memset beforeDan Gohman
updating it with calls to setIndexedLoadAction/setIndexedStoreAction, which only update a few bits at a time. This avoids ostensible undefined behavior of operationg on values which may be trap-representations, and as a practical matter fixes errors from valgrind, which doesn't track uninitialized memory with bit granularity. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@38468 91177308-0d34-0410-b5e6-96231b3b80d8
2007-06-28Add new TargetLowering code to provide the final register type that anDan Gohman
illegal value type will be transformed to, for code that needs the register type after all transformations instead of just after the first transformation. Factor out the code that uses this information to do copy-from-regs and copy-to-regs for various purposes into separate functions so that they are done consistently. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37781 91177308-0d34-0410-b5e6-96231b3b80d8
2007-06-25Generalize MVT::ValueType and associated functions to be able to representDan Gohman
extended vector types. Remove the special SDNode opcodes used for pre-legalize vector operations, and the special MVT::Vector type used with them. Adjust lowering and legalize to work with the normal SDNode kinds instead, and to use the normal MVT functions to work with vector types instead of using the two special operands that the pre-legalize nodes held. This allows pre-legalize and post-legalize DAGs, and the code that operates on them, to be more consistent. Pre-legalize vector operators can be handled more consistently with scalar operators. And, -view-dag-combine1-dags and -view-legalize-dags now look prettier for vector code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37719 91177308-0d34-0410-b5e6-96231b3b80d8
2007-06-22Move ComputeMaskedBits, MaskedValueIsZero, and ComputeNumSignBits fromDan Gohman
TargetLowering to SelectionDAG so that they have more convenient access to the current DAG, in preparation for the ValueType routines being changed from standalone functions to members of SelectionDAG for the pre-legalize vector type changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37704 91177308-0d34-0410-b5e6-96231b3b80d8

2007-06-21Rename TargetLowering::getNumElements and friends toDan Gohman
TargetLowering::getNumRegisters and similar, to avoid confusion with the actual number of elements for vector types. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37687 91177308-0d34-0410-b5e6-96231b3b80d8
