2009-11-07It turns out that the testcase in question uncovered subreg-handling bug.Anton Korobeynikov
Add assert in asmprinter to catch such cases and xfail the tests. PR is to be filled. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@86375 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-07add the ability for TargetData to return information about legal integerChris Lattner
datatypes on a given CPU. This is intended to allow instcombine and other transformations to avoid converting big sequences of operations to an inconvenient width, and will help clean up after SRoA. See also "Adding legal integer sizes to TargetData" on Feb 1, 2009 on llvmdev, and PR3451. Comments welcome. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@86370 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-07Make the need-stub variables accurate and consistent. In the case ofJeffrey Yasskin
MachineRelocations, "stub" always refers to a far-call stub or a load-a-faraway-global stub, so this patch adds "Far" to the term. (Other stubs are used for lazy compilation and dlsym address replacement.) The variable was also inconsistent between the positive and negative sense, and the positive sense ("NeedStub") was more demanding than is accurate (since a nearby-enough function can be called directly even if the platform often requires a stub). Since the negative sense causes double-negatives, I switched to "MayNeedFarStub" globally. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@86363 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-07- Add TargetInstrInfo::isIdentical(). It's similar to MachineInstr::isIdenticalEvan Cheng
except it doesn't care if the definitions' virtual registers differ. This is used by machine LICM and other MI passes to perform CSE. - Teach Thumb2InstrInfo::isIdentical() to check two t2LDRpci_pic are identical. Since pc relative constantpool entries are always different, this requires it it check if the values can actually the same. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@86328 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-07My previous patch (r84124) for setting the encoding bits 4 and 7 of DPSoRegFrmJohnny Chen
was wrong and too aggressive in the sense that DPSoRegFrm includes both constant shifts (with Inst{4} = 0) and register controlled shifts (with Inst{4} = 1 and Inst{7} = 0). The 'rr' fragment of the multiclass definitions actually means register/register with no shift, see A8-11. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@86319 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-07Re-commit r86077 now that r86290 fixes the 179.art and 175.vpr ARM regressions.Victor Hernandez
Here is the original commit message: This commit updates malloc optimizations to operate on malloc calls that have constant int size arguments. Update CreateMalloc so that its callers specify the size to allocate: MallocInst-autoupgrade users use non-TargetData-computed allocation sizes. Optimization uses use TargetData to compute the allocation size. Now that malloc calls can have constant sizes, update isArrayMallocHelper() to use TargetData to determine the size of the malloced type and the size of malloced arrays. Extend getMallocType() to support malloc calls that have non-bitcast uses. Update OptimizeGlobalAddressOfMalloc() to optimize malloc calls that have non-bitcast uses. The bitcast use of a malloc call has to be treated specially here because the uses of the bitcast need to be replaced and the bitcast needs to be erased (just like the malloc call) for OptimizeGlobalAddressOfMalloc() to work correctly. Update PerformHeapAllocSRoA() to optimize malloc calls that have non-bitcast uses. The bitcast use of the malloc is not handled specially here because ReplaceUsesOfMallocWithGlobal replaces through the bitcast use. Update OptimizeOnceStoredGlobal() to not care about the malloc calls' bitcast use. Update all globalopt malloc tests to not rely on autoupgraded-MallocInsts, but instead use explicit malloc calls with correct allocation sizes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@86311 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-06- Add pseudo instructions tLDRpci_pic and t2LDRpci_pic which does a pc-relativeEvan Cheng
load of a GV from constantpool and then add pc. It allows the code sequence to be rematerializable so it would be hoisted by machine licm. - Add a late pass to break these pseudo instructions into a number of real instructions. Also move the code in Thumb2 IT pass that breaks up t2MOVi32imm to this pass. This is done before post regalloc scheduling to allow the scheduler to proper schedule these instructions. It also allow them to be if-converted and shrunk by later passes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@86304 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-06Extend jump threading to support much more general threadingChris Lattner
predicates. This allows us to jump thread things like: _ZN12StringSwitchI5ColorE4CaseILj7EEERS1_RAT__KcRKS0_.exit119: %tmp1.i24166 = phi i8 [ 1, %bb5.i117 ], [ %tmp1.i24165, %_Z....exit ], [ %tmp1.i24165, %bb4.i114 ] %toBoolnot.i87 = icmp eq i8 %tmp1.i24166, 0 ; <i1> [#uses=1] %tmp4.i90 = icmp eq i32 %tmp2.i, 6 ; <i1> [#uses=1] %or.cond173 = and i1 %toBoolnot.i87, %tmp4.i90 ; <i1> [#uses=1] br i1 %or.cond173, label %bb4.i96, label %_ZN12... Where it is "obvious" that when coming from %bb5.i117 that the 'and' is always false. This triggers a surprisingly high number of times in the testsuite, and gets us closer to generating good code for doug's strswitch testcase. This also make a bunch of other code in jump threading redundant, I'll rip out in the next patch. This survived an enable-checking llvm-gcc bootstrap. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@86264 91177308-0d34-0410-b5e6-96231b3b80d8
