2011-10-27Remove the Alpha backend.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@143164 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-06Add codegen support for vector select (in the IR this means a selectDuncan Sands
with a vector condition); such selects become VSELECT codegen nodes. This patch also removes VSETCC codegen nodes, unifying them with SETCC nodes (codegen was actually often using SETCC for vector SETCC already). This ensures that various DAG combiner optimizations kick in for vector comparisons. Passes dragonegg bootstrap with no testsuite regressions (nightly testsuite as well as "make check-all"). Patch mostly by Nadav Rotem. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139159 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-29Expand ATOMIC_LOAD and ATOMIC_STORE for architectures I don't know well ↵Eli Friedman
enough to fix properly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138751 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-03New approach to r136737: insert the necessary fences for atomic ops in ↵Eli Friedman
platform-independent code, since a bunch of platforms (ARM, Mips, PPC, Alpha are the relevant targets here) need to do essentially the same thing. I think this completes the basic CodeGen for atomicrmw and cmpxchg. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136813 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-08Add an intrinsic and codegen support for fused multiply-accumulate. The intentCameron Zwarich
is to use this for architectures that have a native FMA instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134742 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-30Make sure we use the correct register class here since we'll need toEric Christopher
care about spill values. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134122 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-08Add a parameter to CCState so that it can access the MachineFunction.Eric Christopher
No functional change. Part of PR6965 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132763 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-06Make the logic for determining function alignment more explicit. No ↵Eli Friedman
functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@131012 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-15Fix a ton of comment typos found by codespell. Patch byChris Lattner
Luis Felipe Strano Moraes! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129558 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-25Allow targets to specify a the type of the RHS of a shift parameterized on ↵Owen Anderson
the type of the LHS. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126518 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-16Swap VT and DebugLoc operands of getExtLoad() for consistency withStuart Hastings
other getNode() methods. Radar 9002173. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125665 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-21rename MVT::Flag to MVT::Glue. "Flag" is a terrible name forChris Lattner
something that just glues two nodes together, even if it is sometimes used for flags. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@122310 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-23Renaming ISD::BIT_CONVERT to ISD::BITCAST to better reflect the LLVM IR concept.Wesley Peck
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119990 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-29Inline asm multiple alternative constraints development phase 2 - improved ↵John Thompson
basic logic, added initial platform support. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117667 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-21update a bunch of code to use the MachinePointerInfo version of getStore.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114461 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-21eliminate an old SelectionDAG::getTruncStore method, propagatingChris Lattner
MachinePointerInfo around more. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114452 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-21propagate MachinePointerInfo through various uses of the oldChris Lattner
SelectionDAG::getExtLoad overload, and eliminate it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114446 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-21convert the targets off the non-MachinePointerInfo of getLoad.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114410 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-07Move getExtLoad() and (some) getLoad() DebugLoc argument after EVT argument ↵Evan Cheng
for consistency sake. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107820 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-07Split the SDValue out of OutputArg so that SelectionDAG-independentDan Gohman
code can do calling-convention queries. This obviates OutputArgReg. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107786 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-06Propagate debug loc.Devang Patel
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107710 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-06Reapply r107655 with fixes; insert the pseudo instruction intoDan Gohman
the block before calling the expansion hook. And don't put EFLAGS in a mbb's live-in list twice. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107691 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-06Revert r107655.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107668 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-06Fix a bunch of custom-inserter functions to handle the case whereDan Gohman
the pseudo instruction is not at the end of the block. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107655 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-03Remove isSS argument from CreateFixedObject. Fixed objects cannot be spill ↵Evan Cheng
slots so it's always false. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107550 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-01Get rid of the EdgeMapping map. Instead, just check for BasicBlockDan Gohman
changes before doing phi lowering for switches. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102809 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-17Use const qualifiers with TargetLowering. This eliminates severalDan Gohman
const_casts, and it reinforces the design of the Target classes being immutable. SelectionDAGISel::IsLegalToFold is now a static member function, because PIC16 uses it in an unconventional way. There is more room for API cleanup here. And PIC16's AsmPrinter no longer uses TargetLowering. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101635 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-17Move per-function state out of TargetLowering subclasses and intoDan Gohman
MachineFunctionInfo subclasses. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101634 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-15Add const qualifiers to CodeGen's use of LLVM IR constructs.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101334 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-02use DebugLoc default ctor instead of DebugLoc::getUnknownLoc()Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100214 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-15Move TLOF implementations to libCodegen to resolve layering violation.Anton Korobeynikov
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96288 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-15Remove an assumption of default arguments. This is in anticipation of aDavid Greene
change to SelectionDAG build APIs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96229 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95160 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-02Pass callsite return type to TargetLowering::LowerCall and use that to check ↵Evan Cheng
sibcall eligibility. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95130 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-27Eliminate target hook IsEligibleForTailCallOptimization.Evan Cheng
Target independent isel should always pass along the "tail call" property. Change target hook LowerCall's parameter "isTailCall" into a refernce. If the target decides it's impossible to honor the tail call request, it should set isTailCall to false to make target independent isel happy. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94626 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-26eliminate the TargetLowering::UsesGlobalOffsetTable bool, which isChris Lattner
subsumed by TargetLowering::getJumpTableEncoding(). Change uses of it to be more specific. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94529 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92194 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-23Remove ISD::DEBUG_LOC and ISD::DBG_LABEL, which are no longer used.Dan Gohman
Note that "hasDotLocAndDotFile"-style debug info was already broken; people wanting this functionality should implement it in the AsmPrinter/DwarfWriter code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89711 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-21We are not using DBG_STOPPOINT anymore.Devang Patel
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89536 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-12Add a bool flag to StackObjects telling whether they reference spillDavid Greene
slots. The AsmPrinter will use this information to determine whether to print a spill/reload comment. Remove default argument values. It's too easy to pass a wrong argument value when multiple arguments have default values. Make everything explicit to trap bugs early. Update all targets to adhere to the new interfaces.. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@87022 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-28Add a second ValueType argument to isFPImmLegal.Evan Cheng
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85361 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-27Do away with addLegalFPImmediate. Add a target hook isFPImmLegal which ↵Evan Cheng
returns true if the fp immediate can be natively codegened by target. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85281 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82355 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-19Fix PR4926. When target hook EmitInstrWithCustomInserter() insert new basic ↵Evan Cheng
blocks and update CFG, it should also inform sdisel of the changes so the phi source operands will come from the right basic blocks. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82311 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-18Enhance EmitInstrWithCustomInserter() so target can specify CFG changes that ↵Evan Cheng
sdisel will use to properly complete phi nodes. Not functionality change yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82273 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80773 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-11Split EVT into MVT and EVT, the former representing _just_ a primitive type, ↵Owen Anderson
while the latter is capable of representing either a primitive or an extended type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78713 91177308-0d34-0410-b5e6-96231b3b80d8
