* [msan] Make msan-handle-icmp-exact=0 by default.Evgeniy Stepanov2013-01-281-1/+1
| | | | | | 50% slowdown on one of the specs. llvm-svn: 173678
* Fix 256-bit PALIGNR comment decoding to understand that it works on ↵Craig Topper2013-01-281-2/+11
| | | | | | independent 256-bit lanes. llvm-svn: 173674
* A bugfix for tblgen, in the function ‘emitSourceFileHeader’.Nadav Rotem2013-01-281-6/+25
| | | | | | | | | When the first parameter (‘Desc’) is more than 80 characters long, it will result the header line that contains the description to be more Than (4GB!) long. Not only it takes forever to produce, the output file cannot be open, since its ginormous. Patch by Elior Malul. llvm-svn: 173672
* Add missing break in 256-bit palignr comment printing. No test case yet ↵Craig Topper2013-01-281-0/+1
| | | | | | because the comment itself is still wrong. llvm-svn: 173669
* Fix inconsistent usage of PALIGN and PALIGNR when referring to the same ↵Craig Topper2013-01-287-34/+35

* Created ObjCARCUtil.cpp for functions which in my humble opinion are too ↵Michael Gottesman2013-01-283-126/+152
| | | | | | large to static inline and place in a header file such as ObjCARC.h. llvm-svn: 173666
* Remove addToNoHelperNeeded function that was left unused after r173649. ↵Craig Topper2013-01-281-6/+0
| | | | | | Fixes a -Wunused warning. llvm-svn: 173664
* Cleaned up includes in various ObjCARC files and removed some whitespace ↵Michael Gottesman2013-01-284-9/+34
| | | | | | violations. llvm-svn: 173663
* Refactor ObjCARCAliasAnalysis into its own file.Michael Gottesman2013-01-285-283/+352

* Mid-air collision. reapply r173656.Bill Wendling2013-01-281-5/+5
| | | | llvm-svn: 173661
* Rewrite the removeAttr() method.Bill Wendling2013-01-281-42/+40
| | | | | | | | | | This now uses the AttributeSet object instead of the Attribute / AttributeWithIndex objects. It's fairly simple now. It goes through all of the subsets before the one we're modifying, adds them to the new set. It then adds the modified subset (with the requested attributes removed). And then adds the rest of the subsets. llvm-svn: 173660

* Revert r173646, "Use proper type for the index."NAKAMURA Takumi2013-01-281-7/+7
| | | | | | Unfortunately, msvc miscompiles it. Investigating. llvm-svn: 173656
* Refactored out pass ObjCARCAPElim from ObjCARCOpts.cpp => ObjCARCAPElim.cpp.Michael Gottesman2013-01-283-148/+183

| | | | llvm-svn: 173652
* Extracted pass ObjCARCExpand from ObjCARC.cpp => ObjCARCExpand.cpp.Michael Gottesman2013-01-285-299/+370
| | | | | | | I also added the local header ObjCARC.h for common functions used by the various passes. llvm-svn: 173651
* Make some code a little simpler.Reed Kotler2013-01-282-40/+40

* Remove a use of AttributeWithIndex.Bill Wendling2013-01-282-13/+33
| | | | | | | | | | We want to remove AttributeWithIndex because it provides a non-encapsulated view of the AttributeSetImpl object. Instead, use accessor methods and iterators. Eventually, this code can be simplified because the Attribute object will hold only one attribute instead of multiple attributes. llvm-svn: 173641
* Improve the debug output a bit.Bill Wendling2013-01-271-2/+7

* Push the calculation of the 'Raw' attribute mask down into the ↵Bill Wendling2013-01-272-9/+25
| | | | | | implementation. It in turn uses the correct list for calculating the 'Raw' value. llvm-svn: 173637

* [XCore] Add missing l2rus instructions.Richard Osborne2013-01-272-1/+14
| | | | | | | These instructions are not targeted by the compiler but they are needed for the MC layer. llvm-svn: 173634
* Privitize some the copy c'tor and assignment operator of uniquified objects.Bill Wendling2013-01-271-0/+8

| | | | llvm-svn: 173628
* Start using more of the AttrNode in the AttributeSetImpl class.Bill Wendling2013-01-272-10/+11
| | | | | | Also add some asserts. llvm-svn: 173627

* BBVectorize: Better use of TTI->getShuffleCostHal Finkel2013-01-271-4/+23
| | | | | | | | | | | | | | | | | | | | When flipping the pair of subvectors that form a vector, if the vector length is 2, we can use the SK_Reverse shuffle kind to get more-accurate cost information. Also we can use the SK_ExtractSubvector shuffle kind to get accurate subvector extraction costs. The current cost model implementations don't yet seem complex enough for this to make a difference (thus, there are no test cases with this commit), but it should help in future. Depending on how the various targets optimize and combine shuffles in practice, we might be able to get more-accurate costs by combining the costs of multiple shuffle kinds. For example, the cost of flipping the subvector pairs could be modeled as two extractions and two subvector insertions. These changes, however, should probably be motivated by specific test cases. llvm-svn: 173621
* Legalizer: Add an assert and tweak a comment to clarify the assumptions this ↵Benjamin Kramer2013-01-271-1/+5

* When the legalizer is splitting vector shifts, the result may not have the ↵Benjamin Kramer2013-01-271-2/+9
| | | | | | | | | | | | | | | right shift amount type. Fix that by adding a cast to the shift expander. This came up with vector shifts on sse-less X86 CPUs. <2 x i64> = shl <2 x i64> <2 x i64> -> i64,i64 = shl i64 i64; shl i64 i64 -> i32,i32,i32,i32 = shl_parts i32 i32 i64; shl_parts i32 i32 i64 Now we cast the last two i64s to the right type. Fixes the crash in PR14668. llvm-svn: 173615

* Renamed function IsPotentialUse to IsPotentialRetainableObjPtr.Michael Gottesman2013-01-271-18/+18
| | | | | | | | | This name change does the following: 1. Causes the function name to use proper ARC terminology. 2. Makes it clear what the function truly does. llvm-svn: 173609
* Use the AttributeSet instead of AttributeWithIndex.Bill Wendling2013-01-271-33/+33
| | | | | | | In the future, AttributeWithIndex won't be used anymore. Besides, it exposes the internals of the AttributeSet to outside users, which isn't goodness. llvm-svn: 173603
