* CellSPU:Scott Michel2009-01-211-0/+4
| | | | | | | | | | | | | - Ensure that (operation) legalization emits proper FDIV libcall when needed. - Fix various bugs encountered during llvm-spu-gcc build, along with various cleanups. - Start supporting double precision comparisons for remaining libgcc2 build. Discovered interesting DAGCombiner feature, which is currently solved via custom lowering (64-bit constants are not legal on CellSPU, but DAGCombiner insists on inserting one anyway.) - Update README. llvm-svn: 62664
* Allow targets to legalize operations (with illegal operands) that produces ↵Sanjiv Gupta2009-01-215-68/+85
| | | | | | multiple values. For example, a load with an illegal operand (a load produces two values, a value and chain). llvm-svn: 62663
* Be more aggressive about renumbering vregs after splitting them.Owen Anderson2009-01-211-3/+7

* Fix PR3243: a LiveVariables bug. When HandlePhysRegKill is checking whether ↵Evan Cheng2009-01-201-13/+15
| | | | | | the last reference is also the last def (i.e. dead def), it should also check if last reference is the current machine instruction being processed. This can happen when it is processing a physical register use and setting the current machine instruction as sub-register's last ref. llvm-svn: 62617
* Use "SINT_TO_FP" instead of "UINT_TO_FP" when getting the exponent. This wasBill Wendling2009-01-201-12/+13
| | | | | | | causing the limited precision stuff to produce the wrong result for values in the range [0, 1). llvm-svn: 62615

* Fix a dagcombine to not generate loads of non-round integer types,Dan Gohman2009-01-201-1/+1
| | | | | | | as its comment says, even in the case where it will be generating extending loads. This fixes PR3216. llvm-svn: 62557
* Do not use DenseMap because the iterator is invalidated while constructing ↵Devang Patel2009-01-201-2/+2
| | | | | | types. After all there was a reason why std::map was used initially! llvm-svn: 62555
* Make linear scan's trivial coalescer slightly more aggressive.Evan Cheng2009-01-201-6/+6
| | | | llvm-svn: 62547
* Verify debug info.Devang Patel2009-01-193-10/+27

* Remove SDNode's virtual destructor. This makes it impossible forDan Gohman2009-01-191-53/+14
| | | | | | | | | | | | | | SDNode subclasses to keep state that requires non-trivial destructors, however it was already effectively impossible, since the destructor isn't actually ever called. There currently aren't any SDNode subclasses affected by this, and in general it's desireable to keep SDNode objects light-weight. This eliminates the last virtual member function in the SDNode class, so it eliminates the need for a vtable pointer, making SDNode smaller. llvm-svn: 62539
* Fix SelectionDAG::ReplaceAllUsesWith to behave correctly whenDan Gohman2009-01-192-16/+39
| | | | | | | | | | | | | uses are added to the From node while it is processing From's use list, because of automatic local CSE. The fix is to avoid visiting any new uses. Fix a few places in the DAGCombiner that assumed that after a RAUW call, the From node has no users and may be deleted. This fixes PR3018. llvm-svn: 62533

* Instead of adding dependence edges between terminator instructionsDan Gohman2009-01-166-25/+65
| | | | | | | | | | | | | | and every other instruction in their blocks to keep the terminator instructions at the end, teach the post-RA scheduler how to operate on ranges of instructions, and exclude terminators from the range of instructions that get scheduled. Also, exclude mid-block labels, such as EH_LABEL instructions, and schedule code before them separately from code after them. This fixes problems with the post-RA scheduler moving code past EH_LABELs. llvm-svn: 62366
* If an anti-dependence uses a non-allocatable register, set AntiDepRegDan Gohman2009-01-161-1/+3
| | | | | | | to 0, to ensure that the subsequent code doesn't try to break the dependence. llvm-svn: 62365
* Use the getNode() accessor instead of accessing the NodeDan Gohman2009-01-161-1/+1
| | | | | | member directly, which is private as of r55504. llvm-svn: 62364
* Fix the check for an empty basic block to check for an empty SUnitsDan Gohman2009-01-161-2/+2
| | | | | | | | array instead, since this is what the scheduler actually cares about. And remove a check that is unnecessary, since it can assume that SUnits isn't empty. llvm-svn: 62362

* CreateVirtualRegisters does trivial copy coalescing. If a node def is used ↵Evan Cheng2009-01-162-56/+63
| | | | | | by a single CopyToReg, it reuses the virtual register assigned to the CopyToReg. This won't work for SDNode that is a clone or is itself cloned. Disable this optimization for those nodes or it can end up with non-SSA machine instructions. llvm-svn: 62356
* Use lightweight DebugInfo objects directly.Devang Patel2009-01-161-51/+50

* Registry.h should not depend on CommandLine.h.Mikhail Glushenkov2009-01-164-0/+4
| | | | | | | Split Support/Registry.h into two files so that we have less to recompile every time CommandLine.h is changed. llvm-svn: 62312

* Any debug info symbol is only valid if atleast one compile unit is seen.Devang Patel2009-01-161-0/+4
| | | | llvm-svn: 62294
* Initial hazard recognizer support in post-pass scheduling. This includesDan Gohman2009-01-162-9/+120
| | | | | | | a new toy hazard recognizier heuristic which attempts to direct the scheduler to avoid clumping large groups of loads or stores too densely. llvm-svn: 62291
* Do not stumble over forward declared struct member. Devang Patel2009-01-161-0/+5
| | | | llvm-svn: 62288
* Validate dbg_* intrinsics before lowering them.Devang Patel2009-01-153-10/+55

* Added missing support to widen an operand from a bit convert.Mon P Wang2009-01-152-0/+32
| | | | llvm-svn: 62285
* Generalize the HazardRecognizer interface so that it can be usedDan Gohman2009-01-153-23/+14
| | | | | | | to support MachineInstr-based scheduling in addition to SDNode-based scheduling. llvm-svn: 62284
* Simplify the MachineLICM pass by having it only traverse outerDan Gohman2009-01-151-122/+60
| | | | | | | | | loops, hoisting instructions all the way out in one step rather than hoisting them one nest level at a time. Also, make a few other code simplifications. This speeds up MachineLICM by several fold. llvm-svn: 62283
* Add the private linkage.Rafael Espindola2009-01-155-6/+13
