* Use references to attribute groups on the call/invoke instructions.Bill Wendling2013-02-2240-158/+248
| | | | | | | Listing all of the attributes for the callee of a call/invoke instruction is way too much and makes the IR unreadable. Use references to attributes instead. llvm-svn: 175877
* Fix a nomenclature mistake. Slt->Slti in the functions. The "i" refersReed Kotler2013-02-222-8/+8

* Fix isa<> check which could never be true.Pete Cooper2013-02-222-1/+33
| | | | | | | | | | | | It was incorrectly checking a Function* being an IntrinsicInst* which isn't possible. It should always have been checking the CallInst* instead. Added test case for x86 which ensures we only get one constant load. It was 2 before this change. rdar://problem/13267920 llvm-svn: 175853
* Remove code copied from GenRegisterInfo.inc.Andrew Trick2013-02-222-57/+0
| | | | | | | | There's no apparent reason this code was copied from generated source into a .cpp. It sets a bad example for those working on other targets and trying to understand the register info API. llvm-svn: 175849

* Add a bitmask for NoBuiltin. This should *not* be used.Bill Wendling2013-02-221-1/+2
| | | | llvm-svn: 175843
* Implement the NoBuiltin attribute.Bill Wendling2013-02-2210-35/+66
| | | | | | | | The 'nobuiltin' attribute is applied to call sites to indicate that LLVM should not treat the callee function as a built-in function. I.e., it shouldn't try to replace that function with different code. llvm-svn: 175835
* Stop relying on physical register kill flags in isKilled() in the two-addressCameron Zwarich2013-02-211-3/+10
| | | | | | | | | | | | | | pass. One of the callers of isKilled() can cope with overapproximation of kills and the other can't, so I added a flag to indicate this. In theory this could pessimize code slightly, but in practice most physical register uses are kills, and most important kills of physical registers are the only uses of that register prior to register allocation, so we can recognize them as kills even without kill flags. This is relevant because LiveIntervals gets rid of all kill flags. llvm-svn: 175821
* Previously, parsing capability of the .debug_frame section was addedEli Bendersky2013-02-213-6/+184
| | | | | | | | | | | | | | | | to lib/DebugInfo, with dumping in llvm-dwarfdump. This patch adds initial ability to parse and dump CFA instructions contained in entries. To keep it manageable, the patch omits some more advanced capabilities (accounted in TODOs): * Parsing of instructions with BLOCK arguments (expression lists) * Dumping of actual instruction arguments (currently only names are dumped). This is quite tricky since the dumper has to effectively "interpret" the instructions. llvm-svn: 175820
* Limit cast machinery to preserve const and not accept temporariesDavid Blaikie2013-02-211-5/+47
| | | | | | | | | | | | | | | | | | | | | | | After cleaning up the following type hierarchies: * TypeLoc: r175462 * SVal: r175594 * CFGElement: r175462 * ProgramPoint: r175812 that all invoked undefined behavior by causing a derived copy construction of a base object through an invalid cast (thus supporting code that relied on casting temporaries that were direct base objects) Clang/LLVM is now clean of casts of temporaries. So here's some fun SFINAE machinery (courtesy of Eli Friedman, with some porting back from C++11 to LLVM's traits by me) to cause compile-time failures if llvm::cast & friends are ever passed an rvalue. This should avoid a repeat of anything even remotely like PR14321/r168124. Thanks to Jordan Rose for the help with the various Static Analyzer related hierarchies that needed cleaning up, Eli for the SFINAE, Richard Smith, John McCall, Ted Kremenek, and Anna Zaks for their input/reviews/patience along the way. llvm-svn: 175819
* Allow GlobalValues to vectorize with AliasAnalysisRenato Golin2013-02-212-35/+510
| | | | | | | | | | | | | | | | | | | | | Storing the load/store instructions with the values and inspect them using Alias Analysis to make sure they don't alias, since the GEP pointer operand doesn't take the offset into account. Trying hard to not add any extra cost to loads and stores that don't overlap on global values, AA is *only* calculated if all of the previous attempts failed. Using biggest vector register size as the stride for the vectorization access, as we're being conservative and the cost model (which calculates the real vectorization factor) is only run after the legalization phase. We might re-think this relationship in the future, but for now, I'd rather be safe than sorry. llvm-svn: 175818

* Move the eliminateCallFramePseudoInstr method from TargetRegisterInfoEli Bendersky2013-02-2156-587/+558
| | | | | | | | | | | | | | | to TargetFrameLowering, where it belongs. Incidentally, this allows us to delete some duplicated (and slightly different!) code in TRI. There are potentially other layering problems that can be cleaned up as a result, or in a similar manner. The refactoring was OK'd by Anton Korobeynikov on llvmdev. Note: this touches the target interfaces, so out-of-tree targets may be affected. llvm-svn: 175788

* Make RAFast::UsedInInstr indexed by register units.Jakob Stoklund Olesen2013-02-213-22/+45

* Large code model support for PowerPC.Bill Schmidt2013-02-2115-109/+227
| | | | | | | | | | | Large code model is identical to medium code model except that the addis/addi sequence for "local" accesses is never used. All accesses use the addis/ld sequence. The coding changes are straightforward; most of the patch is taken up with creating variants of the medium model tests for large model. llvm-svn: 175767

* getX86SubSuperRegister has a special mode with High=true for i64 whichEli Bendersky2013-02-211-17/+9
| | | | | | | | | | exists solely to enable it to call itself for i8 with some registers. The proposed patch simplifies the function somewhat to make the High bit only meaningful for the i8 mode, which makes sense. No functional difference (getX86SubSuperRegister is not getting called from anywhere outside with i64 and High=true). llvm-svn: 175762
* DAGCombiner: Make the post-legalize vector op optimization more aggressive.Benjamin Kramer2013-02-212-12/+0
