It was incorrectly checking a Function* being an IntrinsicInst* which isn't possible. It should always have been checking the CallInst* instead.

2013-02-22Implement the NoBuiltin attribute.Bill Wendling10-35/+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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175835 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-21Stop relying on physical register kill flags in isKilled() in the two-addressCameron Zwarich1-3/+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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175821 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-21Previously, parsing capability of the .debug_frame section was addedEli Bendersky3-6/+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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175820 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-21Limit cast machinery to preserve const and not accept temporariesDavid Blaikie1-5/+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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175819 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-21Allow GlobalValues to vectorize with AliasAnalysisRenato Golin2-35/+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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175818 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-21Move the eliminateCallFramePseudoInstr method from TargetRegisterInfoEli Bendersky56-587/+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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175788 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-21Large code model support for PowerPC.Bill Schmidt15-109/+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.
