* Use a temporary variable, rather then a series of redundant calls.Chad Rosier2012-02-151-4/+5
| | | | llvm-svn: 150536
* Fix global live range splitting regmask accuracy.Jakob Stoklund Olesen2012-02-141-1/+2
| | | | | | | | Pretend that regmask interference ends at the 'dead' slot, even when there is other interference ending at the 'reg' slot of the same instruction. llvm-svn: 150531
* Fix details in local live range splitting with regmasks.Jakob Stoklund Olesen2012-02-141-6/+16
| | | | | | | Perform all comparisons at instruction granularity, and make sure register masks on uses count in both gaps. llvm-svn: 150530
* Handle regmasks in findRegisterDefOperandIdx().Jakob Stoklund Olesen2012-02-141-0/+4
| | | | | | | | | | | Only accept register masks when looking for an 'overlapping' def. When Overlap is not set, the function searches for a proper definition of Reg. This means MI->modifiesRegister() considers register masks, but MI->definesRegister() doesn't. llvm-svn: 150529
* Use the proper clobber check in handleLiveInRegister().Jakob Stoklund Olesen2012-02-141-1/+1
| | | | | | | | | | | | When a physreg is live in to a basic block, look for any instruction in the block that clobbers the physreg. The instruction doesn't have to properly redefine the register, any overlapping clobber is OK. This slightly changes live ranges when compiling with register masks. llvm-svn: 150528
* Dump live intervals in numerical order.Jakob Stoklund Olesen2012-02-141-4/+15
| | | | | | The old DenseMap hashed order was very confusing. llvm-svn: 150527

* Add code to the target lowering object file module to handle module flags.Bill Wendling2012-02-142-0/+64
| | | | | | | | The MachO back-end needs to emit the garbage collection flags specified in the module flags. This is a WIP, so the front-end hasn't been modified to emit these flags just yet. Documentation and front-end switching to occur soon. llvm-svn: 150507
* Update MachineVerifier to check the new physreg live-in rules.Lang Hames2012-02-141-0/+22

| | | | | | | | that are greater than the vector element type. For example BUILD_VECTOR of type <1 x i1> with a constant i8 operand. This patch fixes the assertion. llvm-svn: 150477

| | | | llvm-svn: 150444
* Add simplifyLoopLatch to LoopRotate pass.Andrew Trick2012-02-141-0/+103
| | | | | | This folds a simple loop tail into a loop latch. It covers the common (in fortran) case of postincrement loops. It's a "free" way to expose this type of loop to downstream loop optimizations that bail out on non-canonical loops (getLoopLatch is a heavily used check). llvm-svn: 150439

* Add register mask support to ScheduleDAGRRList.Jakob Stoklund Olesen2012-02-131-11/+49
| | | | | | | | | The scheduler will sometimes check the implicit-def list on instructions to properly handle pre-colored DAG edges. Also check any register mask operands for physreg clobbers. llvm-svn: 150428

* Fix various issues (or do cleanups) found by enabling certain MSVC warnings.Ahmed Charles2012-02-134-7/+8
| | | | | | | | | - Use unsigned literals when the desired result is unsigned. This mostly allows unsigned/signed mismatch warnings to be less noisy even if they aren't on by default. - Remove misplaced llvm_unreachable. - Add static to a declaration of a function on MSVC x86 only. - Change some instances of calling a static function through a variable to simply calling that function while removing the unused variable. llvm-svn: 150364

* Fixed bug when custom lowering DEC64m on x86.Pete Cooper2012-02-131-0/+1
| | | | | | | | | If the DEC node had more than one user, it was doing this lowering but leaving the original DEC node around and so decrementing twice. Fixes PR11964. llvm-svn: 150356
* This patch addresses the problem of poor code generation for the zextNadav Rotem2012-02-121-14/+29
| | | | | | | | | | | | | | | | | | | v8i8 -> v8i32 on AVX machines. The codegen often scalarizes ANY_EXTEND nodes. The DAGCombiner has two optimizations that can mitigate the problem. First, if all of the operands of a BUILD_VECTOR node are extracted from an ZEXT/ANYEXT nodes, then it is possible to create a new simplified BUILD_VECTOR which uses UNDEFS/ZERO values to eliminate the scalar ZEXT/ANYEXT nodes. Second, another dag combine optimization lowers BUILD_VECTOR into a shuffle vector instruction. In the case of zext v8i8->v8i32 on AVX, a value in an XMM register is to be shuffled into a wide YMM register. This patch modifes the second optimization and allows the creation of shuffle vectors even when the newly generated vector and the original vector from which we extract the values are of different types. llvm-svn: 150340

In particular, the DyldELFObject subclass is now moved into its logical home - ExecutionEngine/RuntimeDyld. This patch was reviewed by Michael Spencer. llvm-svn: 150327
