* Add support for putting NamedRegionTimers in TimerGroups, andDan Gohman2008-07-113-22/+33
| | | | | | | | use a timer group for the timers in SelectionDAGISel. Also, Split scheduling out from emitting, to give each their own timer. llvm-svn: 53476
* Trim unnecessary #includes.Dan Gohman2008-07-113-3/+0
| | | | llvm-svn: 53471
* Remove an apparently useless routine: there shouldDuncan Sands2008-07-112-15/+0
| | | | | | | be no need to split the result of a vector RET node, since they are always already legal. llvm-svn: 53462
* It is pointless to turn a UINT_TO_FP into anDuncan Sands2008-07-113-79/+118
| | | | | | | | | 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. llvm-svn: 53461
* Add two missing SINT_TO_FP libcalls.Duncan Sands2008-07-112-11/+21
| | | | llvm-svn: 53460
* Port a shift-by-1 optimization from LegalizeDAG: itDuncan Sands2008-07-111-0/+7
| | | | | | | was presumably added after the rest of the code was copied to LegalizeTypes. llvm-svn: 53459
* Add support for 128 bit shifts and 32 bit shiftsDuncan Sands2008-07-112-6/+23
| | | | | | on 16 bit machines. llvm-svn: 53458
* Fix a bug in the soft-float handling of FCOPYSIGN that Duncan noticedChris Lattner2008-07-101-2/+5
| | | | | | | when working on legalizetypes. Both legalizetypes and legalizeops now produce hte same code for CodeGen/ARM/fcopysign.ll. llvm-svn: 53435
* make legalize types be a command line option: -enable-legalize-types.Chris Lattner2008-07-101-5/+8
| | | | llvm-svn: 53434
* Make stack slot coloring's debug output more consistent withDan Gohman2008-07-101-1/+1

* Change StackSlotForVirtReg (which maps vregs to frame indices) from std::map ↵Evan Cheng2008-07-101-8/+8
| | | | | | to IndexedMap. llvm-svn: 53414
* Add support for 128 bit multiplicative operations.Duncan Sands2008-07-102-21/+62
| | | | | | | | | 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. llvm-svn: 53408
* Add a mysteriously missing libcall, FPTOSINT_F80_I32.Duncan Sands2008-07-104-6/+32
| | | | | | | Be nice to 16 bit machines by supporting FP_TO_XINT expansion for these. llvm-svn: 53407
* Fix a FIXME: use an apint in CTTZ legalization.Duncan Sands2008-07-101-3/+3
| | | | llvm-svn: 53406
* Remove PromoteIntRes_FP_ROUND - not sure what itDuncan Sands2008-07-104-14/+1
| | | | | | | was doing there: FP_ROUND returns a float, not an integer. llvm-svn: 53405
* Make sure the alignment of the temporary createdDuncan Sands2008-07-101-2/+6
| | | | | | | in CreateStackStoreLoad is good enough for both the source and destination types. llvm-svn: 53404
* Make the LegalizeType method naming scheme more regular.Duncan Sands2008-07-105-49/+43

* Don't barf when dumping a constant that containsDuncan Sands2008-07-101-1/+1
| | | | | | a ginormous value (eg: i128 -1). llvm-svn: 53402

| | | | | | | | the operand index of def machineoperand and at most one full scan of non-implicit operands is needed. - Change local register allocator to use the new isRegReDefinedByTwoAddr instead of reinventing the wheel. llvm-svn: 53394
* Use DenseMap instead of std::map in local register allocation. This ↵Owen Anderson2008-07-101-3/+16
| | | | | | improves the time on instcombine from .31s to .22s llvm-svn: 53390
* Fix 403.gcc. Finally got the check for two-address-ness correct.Owen Anderson2008-07-101-10/+14
| | | | llvm-svn: 53389
* Revert r53367, which was breaking things.Owen Anderson2008-07-091-1/+3
| | | | llvm-svn: 53378
* Simplify hasNUsesOfValue and hasAnyUsesOfValue even more. ThisDan Gohman2008-07-091-14/+2
| | | | | | | | | | | 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. llvm-svn: 53377
* hasAnyUseOfValue can check SDUse nodes of its users directly insteadDan Gohman2008-07-091-13/+3

* Move MemoryVT out of LSBaseNode into MemSDNode, allowing theDan Gohman2008-07-091-28/+16
| | | | | | | getMemOperand function to be moved into the base class as well and made non-virtual. llvm-svn: 53372
* Avoid creating expensive comment string if it's not going to be printed.Evan Cheng2008-07-091-1/+4
| | | | llvm-svn: 53369

* Move the IsVolatile and SVOffset fields into the MemSDNode baseDan Gohman2008-07-091-0/+11
| | | | | | | | | | 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. llvm-svn: 53361
* Don't use an expensive check for two-address-ness when we have the ↵Owen Anderson2008-07-091-2/+13

* Reuse the MO variable instead of recomputing it in RegAllocLocal.Dan Gohman2008-07-092-9/+9
| | | | | | Keep RegAllocSimple in sync. llvm-svn: 53351
* Give RegAllocSimple a TargetInstrInfo member to keep it consistentDan Gohman2008-07-091-2/+2

* Redo LegalizeTypes soft float support forDuncan Sands2008-07-092-96/+103
| | | | | | | | | 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). llvm-svn: 53288
