2008-07-14An INSERT_VECTOR_ELT can insert a larger valueDuncan Sands
than the vector element type. Don't forget to handle this when the insertion index is not a constant. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53556 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-14According to the docs, it is possible to have anDuncan Sands
extending load of a vector. Handle this case when splitting vector loads. I'm not completely sure what is supposed to happen, but I think it means hi should be set to undef. LegalizeDAG does not consider this case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53555 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-14There should be no extending loads or truncatingDuncan Sands
stores of one-element vectors. Also, neaten the handling of INSERT_VECTOR_ELT when the inserted type is larger than the vector element type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53554 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-14Ignore TargetConstant with an illegal type. TheseDuncan Sands
are used for passing huge immediates in inline ASM from the front-end straight down to the ASM writer. Of course this is a hack, but it is simple, limited in scope, works in practice, and is what LegalizeDAG does. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53553 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-12Back out 53476 and 53480 for now. Somehow they cause llc to miscompile 179.art.Evan Cheng

2008-07-11Include a frame index in the "fixed stack" pseudo source valueDan Gohman
instead of using the frame index for the SVOffset, which was inconsistent. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53486 91177308-0d34-0410-b5e6-96231b3b80d8

2008-07-11Add support for putting NamedRegionTimers in TimerGroups, andDan Gohman
use a timer group for the timers in SelectionDAGISel. Also, Split scheduling out from emitting, to give each their own timer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53476 91177308-0d34-0410-b5e6-96231b3b80d8

2008-07-11Remove an apparently useless routine: there shouldDuncan Sands
be no need to split the result of a vector RET node, since they are always already legal. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53462 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-11It is pointless to turn a UINT_TO_FP into anDuncan Sands
SINT_TO_FP libcall plus additional operations: it might as well be a direct UINT_TO_FP libcall. So only turn it into an SINT_TO_FP if the target has special handling for SINT_TO_FP. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53461 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-11Add two missing SINT_TO_FP libcalls.Duncan Sands
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53460 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-11Port a shift-by-1 optimization from LegalizeDAG: itDuncan Sands
was presumably added after the rest of the code was copied to LegalizeTypes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53459 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-11Add support for 128 bit shifts and 32 bit shiftsDuncan Sands
on 16 bit machines. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53458 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-10Fix a bug in the soft-float handling of FCOPYSIGN that Duncan noticedChris Lattner
when working on legalizetypes. Both legalizetypes and legalizeops now produce hte same code for CodeGen/ARM/fcopysign.ll. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53435 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-10make legalize types be a command line option: -enable-legalize-types.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53434 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-10Add support for 128 bit multiplicative operations.Duncan Sands
Lack of these caused a bootstrap failure with Fortran on x86-64 with LegalizeTypes turned on. While there, be nice to 16 bit machines and support expansion of i32 too. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53408 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-10Add a mysteriously missing libcall, FPTOSINT_F80_I32.Duncan Sands
Be nice to 16 bit machines by supporting FP_TO_XINT expansion for these. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53407 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53406 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-10Remove PromoteIntRes_FP_ROUND - not sure what itDuncan Sands
was doing there: FP_ROUND returns a float, not an integer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53405 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-10Make sure the alignment of the temporary createdDuncan Sands
in CreateStackStoreLoad is good enough for both the source and destination types. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53404 91177308-0d34-0410-b5e6-96231b3b80d8

2008-07-10Don't barf when dumping a constant that containsDuncan Sands
a ginormous value (eg: i128 -1). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53402 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-09Simplify hasNUsesOfValue and hasAnyUsesOfValue even more. ThisDan Gohman
makes their special-case checks of use_size() less beneficial, so remove them. This eliminates all but one use of use_size(), which is in AssignTopologicalOrder, which uses it only once for each node, and so can reasonably afford to recompute it, as this allows the UsesSize field of SDNode to be removed altogether. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53377 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-09hasAnyUseOfValue can check SDUse nodes of its users directly insteadDan Gohman
of examining every operand of every user. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53374 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-09Move MemoryVT out of LSBaseNode into MemSDNode, allowing theDan Gohman
getMemOperand function to be moved into the base class as well and made non-virtual. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53372 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-09Move the IsVolatile and SVOffset fields into the MemSDNode baseDan Gohman
class, and store IsVolatile and Alignment in a more compact form. This makes AtomicSDNode slightly larger, but it shrinks LoadSDNode and StoreSDNode, which are much more common and are the largest of the SDNode subclasses. Also, this lets the isVolatile() and getAlignment() accessors be non-virtual. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53361 91177308-0d34-0410-b5e6-96231b3b80d8

2008-07-09Redo LegalizeTypes soft float support forDuncan Sands
SINT_TO_FP and UINT_TO_FP. This now produces the same code as LegalizeDAG (the previous code was based on a mistaken idea of what LegalizeDAG did in this case). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53288 91177308-0d34-0410-b5e6-96231b3b80d8

2008-07-09Make the role of MVT::i32 clearer here, and add aDuncan Sands
note since it is not clear whether it is correct. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53284 91177308-0d34-0410-b5e6-96231b3b80d8

2008-07-08Factor out the code for computing an alignment value, and make itDan Gohman
available to getAtomic in addition to just getLoad and getStore, to prevent MachineMemOperands with 0 alignment. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53261 91177308-0d34-0410-b5e6-96231b3b80d8

SDNode's. This improves compile time slightly at -O0 -g. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53246 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-08Remove custom expansion from LegalizeTypes when doingDuncan Sands
soft float: experiments show that targets aren't expecting this for results or for operands. Add support select/select_cc result soft float and correct operand soft float for these. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53245 91177308-0d34-0410-b5e6-96231b3b80d8

soft float. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53231 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-07Pool-allocation for MachineInstrs, MachineBasicBlocks, andDan Gohman
MachineMemOperands. The pools are owned by MachineFunctions. This drastically reduces the number of calls to malloc/free made during the "Emit" phase of scheduling, as well as later phases in CodeGen. Combined with other changes, this speeds up the "instruction selection" phase of CodeGen by 10% in some cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53212 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-07Pool-allocation for SDNodes. The pool is allocated once for each function,Dan Gohman
and reused across SelectionDAGs. This drastically reduces the number of calls to malloc/free made during instruction selection, and improves memory locality. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53211 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-07Fix SDNode::MorphNodeTo (a function used by by SelectNodeTo) toDan Gohman
properly track dead nodes that are on the original SDNode's operand list but not the new one, and have no other uses. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53201 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-07Remove most of the uses of SDOperandPtr, usually replacing it with aDan Gohman
simple const SDOperand*, which is what's usually needed. For AddNodeIDOperands, which is small, just duplicate the function to accept an SDUse*. For SelectionDAG::getNode - Add an overload that accepts SDUse* that copies the operands into a temporary SDOperand array, but also has special-case checks for 0 through 3 operands to avoid the copy in the common cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53183 91177308-0d34-0410-b5e6-96231b3b80d8
