* Assign ordering to nodes created in ExpandNode. Only roughly 1/2 of the functionBill Wendling2009-12-221-84/+237
| | | | | | is finished. llvm-svn: 91942
* Assign ordering to SDNodes in PromoteNode. Also fixing a subtle bug where BSWAPBill Wendling2009-12-222-15/+83
| | | | | | was using "Tmp1" in the first getNode call instead of Node->getOperand(0). llvm-svn: 91936
* Remove minimal CFG sanity checks from verifier.Jakob Stoklund Olesen2009-12-221-18/+0
| | | | | | | | | These checks would often trigger on unreachable statements inserted by bugpoint, leading it astray. It would be nice if we could distinguish unreachable blocks from errors. llvm-svn: 91923
* Allow explicit %reg0 operands beyond what the .td file describes.Jakob Stoklund Olesen2009-12-221-1/+2
| | | | | | ARM uses these to indicate predicates. llvm-svn: 91922
* Allow 0 as an order number. Don't assign an order to formal arguments.Bill Wendling2009-12-222-21/+11

* Add more plumbing. This time in the LowerArguments and "get" functions whichBill Wendling2009-12-225-49/+147
| | | | | | | | return partial registers. This affected the back-end lowering code some. Also patch up some places I missed before in the "get" functions. llvm-svn: 91880

* Now add ordering to SDNodes created by the massive intrinsic lowering function.Bill Wendling2009-12-221-100/+183
| | | | llvm-svn: 91863
* To make things interesting, I added MORE code to set the ordering ofBill Wendling2009-12-221-32/+387
| | | | | | SDNodes. This time in the load/store and limited-precision code. llvm-svn: 91860
* Changed slot index ranges for MachineBasicBlocks to be exclusive of endpoint.Lang Hames2009-12-226-33/+28
| | | | | | This fixes an in-place update bug where code inserted at the end of basic blocks may not be covered by existing intervals which were live across the entire block. It is also consistent with the way ranges are specified for live intervals. llvm-svn: 91859
* Add more plumbing to assign ordering to SDNodes. Have the "getValue" methodBill Wendling2009-12-211-59/+133
| | | | | | | assign the ordering when called. Combine some of the ordering assignments to keep things simple. llvm-svn: 91857

* Assign ordering to more instructions. Incremental check-in.Bill Wendling2009-12-211-57/+156
| | | | llvm-svn: 91846
* - Add a bit more plumbing assigning an order to SDNodes.Bill Wendling2009-12-212-9/+32
| | | | | | - Modify the "dump" method to emit the order of an SDNode. llvm-svn: 91845
* First wave of plumbing for assigning an ordering to SDNodes. This takes care ofBill Wendling2009-12-211-28/+43
| | | | | | a lot of the branching instructions. llvm-svn: 91838
* Place SDNodeOrdering.h in the directory it's used.Bill Wendling2009-12-212-1/+59
| | | | llvm-svn: 91834
* Fix setting and default setting of code model for jit. Do thisEric Christopher2009-12-211-0/+26
| | | | | | | | | | by allowing backends to override routines that will default the JIT and Static code generation to an appropriate code model for the architecture. Should fix PR 5773. llvm-svn: 91824
* Fix a bunch of little errors that Clang complains about when its being pedanticDouglas Gregor2009-12-196-8/+8
| | | | llvm-svn: 91764
* Use 4-arg getVTList) variant instead of generic one, when possibleAnton Korobeynikov2009-12-191-0/+1
| | | | llvm-svn: 91744
* Changes from review:Bill Wendling2009-12-184-143/+67
| | | | | | | | | | | - Move DisableScheduling flag into TargetOption.h - Move SDNodeOrdering into its own header file. Give it a minimal interface that doesn't conflate construction with storage. - Move assigning the ordering into the SelectionDAGBuilder. This isn't used yet, so there should be no functional changes. llvm-svn: 91727
* Increase opportunities to optimize (brcond (srl (and c1), c2)).Evan Cheng2009-12-181-1/+28
| | | | llvm-svn: 91717
* Add Loop contains utility methods for testing whether a loopDan Gohman2009-12-181-1/+1
| | | | | | | | contains another loop, or an instruction. The loop form is substantially more efficient on large loops than the typical code it replaces. llvm-svn: 91654
* Handle ARM inline asm "w" constraints with 64-bit ("d") registers.Bob Wilson2009-12-181-1/+1
| | | | | | | | The change in SelectionDAGBuilder is needed to allow using bitcasts to convert between f64 (the default type for ARM "d" registers) and 64-bit Neon vector types. Radar 7457110. llvm-svn: 91649

* Turn off critical edge splitting for landing pads. The introduction of aBill Wendling2009-12-172-4/+5
| | | | | | | | | | non-landing pad basic block as the successor to a block that ends in an unconditional jump will cause block folding to remove the added block as a successor. Thus eventually removing it AND the landing pad entirely. Critical edge splitting is an optimization, so we can safely turn it off when dealing with landing pads. llvm-svn: 91634
* Temporarily revert 91337. It's causing testcase failures.Bill Wendling2009-12-171-6/+7
| | | | | | | | $ svn merge -c -91337 https://llvm.org/svn/llvm-project/llvm/trunk --- Reverse-merging r91337 into '.': U lib/CodeGen/AsmPrinter/DwarfException.cpp llvm-svn: 91618
* Introduce EVT::getHalfSizedIntegerVT() for use in ExpandUnalignedStore() inKen Dyck2009-12-171-6/+3
| | | | | | | | | | | | | | LegalizeDAG.cpp. Unlike the code it replaces, which simply decrements the simple type by one, getHalfSizedIntegerVT() searches for the smallest simple integer type that is at least half the size of the type it is called on. This approach has the advantage that it will continue working if a new value type (such as i24) is added to MVT. Also, in preparation for new value types, remove the assertions that non-power-of-2 8-bit-mutiple types are Extended when legalizing extload and truncstore operations. llvm-svn: 91614

* Revert this dag combine change:Evan Cheng2009-12-171-13/+0
| | | | | | | | Fold (zext (and x, cst)) -> (and (zext x), cst) DAG combiner likes to optimize expression in the other way so this would end up cause an infinite looping. llvm-svn: 91574
* Reapply r91392, it was only unmasking the bug, and since TOT is still broken ↵Daniel Dunbar2009-12-163-29/+155
