* Continue to hoist uses of getCompileUnit() up. The goal is to get rid of ↵Devang Patel2011-08-152-21/+24
| | | | | | uses of getCompileUnit(). llvm-svn: 137683
* In places where it's using "getFirstNonPHI", skip the landingpad instruction ↵Bill Wendling2011-08-151-5/+8
| | | | | | if necessary. llvm-svn: 137679
* MCTargetAsmParser target match predicate support.Jim Grosbach2011-08-153-2/+5
| | | | | | | | Allow a target assembly parser to do context sensitive constraint checking on a potential instruction match. This will be used, for example, to handle Thumb2 IT block parsing. llvm-svn: 137675
* Add a finalize() hook, that'll let DIBuilder construct compile unit lazily.Devang Patel2011-08-151-0/+4
| | | | llvm-svn: 137673
* Don't sink the instruction to before a landingpad instruction.Bill Wendling2011-08-151-1/+1
| | | | llvm-svn: 137672
* This is somewhat déjà-vu, but avoid using getCompileUnit() as much as ↵Devang Patel2011-08-152-14/+14

* Refactor. Variables are part of compile unit so let CompileUnit create new ↵Devang Patel2011-08-154-123/+129
| | | | | | variable. llvm-svn: 137663
* Add some comments here because the lack of a check for volatile/atomic here ↵Eli Friedman2011-08-151-0/+4
| | | | | | is a bit unusual. llvm-svn: 137662
* Fix PR10656. It's only profitable to use 128-bit inserts and extractsBruno Cardoso Lopes2011-08-151-4/+6
| | | | | | | when AVX mode is one. Otherwise is just more work for the type legalizer. llvm-svn: 137661
* There is no need to maintain a set to keep track of variables that use ↵Devang Patel2011-08-152-8/+2
| | | | | | location expressions. In such cases, AT_location attribute's value will be a label. llvm-svn: 137659

* Simplify. Let DbgVariable keep track of variable's DBG_VALUE machine ↵Devang Patel2011-08-152-55/+24
| | | | | | instruction. llvm-svn: 137656
* Duncan pointed out that the LandingPadInst might read memory. (It might alsoBill Wendling2011-08-153-6/+4
| | | | | | write to memory.) Marking it as such makes some checks for immobility go away. llvm-svn: 137655
* Fix llvm::CloneModule to correctly clone globals. Patch per bug report by ↵Eli Friedman2011-08-151-14/+13
| | | | | | Simon Moll on llvmdev. llvm-svn: 137654

* Atomic load/store support in LICM.Eli Friedman2011-08-152-10/+18

* Enforce the constraint that Rt must be even on LDRD/STRD instructions in ARM ↵Owen Anderson2011-08-151-0/+15

* Remove dead classes.Owen Anderson2011-08-151-33/+0
| | | | llvm-svn: 137643
* The "landingpad" instruction will never be "trivially" dead.Bill Wendling2011-08-151-0/+4
| | | | llvm-svn: 137642
* Fix incorrect encoding of UMAAL and friends. Patch by James Molloy.Owen Anderson2011-08-151-2/+2
| | | | llvm-svn: 137641
* Simplify mapping to variable from its abstract variable info.Devang Patel2011-08-152-29/+18
| | | | | | When a variable is inlined multiple places, abstract variable keeps name, location, type etc.. info and all other concreate instances of the variable directly refers to abstract variable. llvm-svn: 137637
* Fix decoding LDRSB and LDRSH in Thumb1 mode. Patch by James Molloy.Owen Anderson2011-08-151-6/+7
| | | | llvm-svn: 137636
* Fix problems decoding the to/from-lane NEON memory instructions, and add a ↵Owen Anderson2011-08-152-4/+486

* Don't try to sink the landingpad instruction. It's immobile.Bill Wendling2011-08-151-2/+3
| | | | llvm-svn: 137629
* The landingpad instruction isn't loop-invariant.Bill Wendling2011-08-151-0/+3
| | | | llvm-svn: 137628
* Mark the SCC as "might unwind" if we run into a 'resume' instruction.Bill Wendling2011-08-151-2/+3
| | | | llvm-svn: 137627
* Skip the insertion iterator past the landingpad instruction if there.Bill Wendling2011-08-151-0/+1
| | | | llvm-svn: 137626
* Refactor. Global variables are part of compile unit so let CompileUnit ↵Devang Patel2011-08-154-129/+144
| | | | | | create new global variable. llvm-svn: 137621
* Refactor. A subprogram is part of compile unit so let CompileUnit construct ↵Devang Patel2011-08-154-114/+141
| | | | | | new subprogram. llvm-svn: 137618
* Update comment to reflect MC target machine refactor.Jim Grosbach2011-08-151-1/+1
| | | | llvm-svn: 137615
* Add inlining for the new EH scheme.Bill Wendling2011-08-141-17/+146
| | | | | | | | | | | | | This builds off of the current scheme, but instead of llvm.eh.exception and llvm.eh.selector, it uses the landingpad instruction. And instead of llvm.eh.resume, it uses the resume instruction. Because of the invariants in the landing pad instruction, a lot of code that's currently needed to find the appropriate intrinsic calls for an invoke instruction won't be needed once we go to the new EH scheme. The "FIXME"s tell us what to remove after we switch. llvm-svn: 137576
* This transform is not safe. Thanks to Eli for pointing that out!Nick Lewycky2011-08-141-8/+1
| | | | llvm-svn: 137575
* Don't attempt to add 'nsw' when intermediate instructions had no such guarantee.Nick Lewycky2011-08-141-4/+7
| | | | llvm-svn: 137572
* Teach instcombine to preserve the nsw bit by doing an after-the-fact analysisNick Lewycky2011-08-141-3/+54
| | | | | | when combining add and sub instructions. Patch by Pranav Bhandarkar! llvm-svn: 137570
* EE: Provide the symbol "lseek64" explicitly with <unistd.h> on Linux glibc.NAKAMURA Takumi2011-08-142-0/+2
| | | | | | With libcxx, it seems <unistd.h> would not be provided. Thanks to Ryuta Suzuki. llvm-svn: 137567
* Fix PR 10635. When generating integer constants, the constant element type mayNadav Rotem2011-08-131-0/+7
| | | | | | | be illegal, even if the requested vector type is legal. Testcase is one of the disabled ARM tests in the vector-select patch. llvm-svn: 137562
* Expand VMOVQQQQ pseudo instructions.Bob Wilson2011-08-131-0/+46
| | | | | | | Apparently we never added code to expand these pseudo instructions, and in over a year, no one has noticed. Our register allocator must be awesome! llvm-svn: 137551
* Remove the last improper use of getGlobalContext() from LLVM.Nick Lewycky2011-08-131-18/+1
| | | | | | | | | | | | This caused a race condition where a thread calls ~LLVMContextImpl which calls Module::dropAllReferences which calls begin() on an empty ilist that would create the sentinel, which racily accesses the global context. This can not be fixed by locking inside createSentinel because the lock would need to be shared with all users of the global context, including those that reside outside LLVM's own code. llvm-svn: 137546
* Move "atomic" and "volatile" designations on instructions after the opcodeEli Friedman2011-08-123-48/+83
| | | | | | | | | | of the instruction. Note that this change affects the existing non-atomic load and store instructions; the parser now accepts both forms, and the change is noted in the release notes. llvm-svn: 137527
* ARM STR_POST_IMM offset encoding fix in load/store optimizer.Jim Grosbach2011-08-121-13/+10
| | | | | | | | | Tidy up the code a bit and push the definition of the value next to the uses to try to minimize this sort of issue from arising again while I'm at it. rdar://9945172 llvm-svn: 137525
* Fix comment!Bruno Cardoso Lopes2011-08-121-3/+3

* The VPERM2F128 is a AVX instruction which permutes between two 256-bitBruno Cardoso Lopes2011-08-127-0/+132
| | | | | | | | vectors. It operates on 128-bit elements instead of regular scalar types. Recognize shuffles that are suitable for VPERM2F128 and teach the x86 legalizer how to handle them. llvm-svn: 137519
* Move code around and add commentsBruno Cardoso Lopes2011-08-121-11/+13
