2012-11-22Merging r168354: into 3.2 release branchPawel Wodnicki
Make the AttrListPtr object a part of the LLVMContext. When code deletes the context, the AttributeImpls that the AttrListPtr points to are now invalid. Therefore, instead of keeping a separate managed static for the AttrListPtrs that's reference counted, move it into the LLVMContext and delete it when deleting the AttributeImpls. git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_32@168486 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-16Merge r168147 from trunk:Hans Wennborg
Constant::IsThreadDependent(): Use dyn_cast<Constant> instead of cast It turns out that the operands of a Constant are not always themselves Constant. For example, one of the operands of BlockAddress is BasicBlock, which is not a Constant. This should fix the dragonegg-x86_64-linux-gcc-4.6-test build which broke in r168037. git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_32@168193 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-16Merge r168037 from trunk:Hans Wennborg
Make GlobalOpt be conservative with TLS variables (PR14309) For global variables that get the same value stored into them everywhere, GlobalOpt will replace them with a constant. The problem is that a thread-local GlobalVariable looks like one value (the address of the TLS var), but is different between threads. This patch introduces Constant::isThreadDependent() which returns true for thread-local variables and constants which depend on them (e.g. a GEP into a thread-local array), and teaches GlobalOpt not to track such values. git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_32@168192 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-02Enable the assertion in getIntPtrType (I've audited all users of this method andDuncan Sands
they are now all correct; hopefully the buildbots will agree!). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167289 91177308-0d34-0410-b5e6-96231b3b80d8

compute the address space in the one place it was used. Also write the getPointerAddressSpace member in terms of the getPointerOperandType member. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167226 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-01Teach Type::getPointerAddressSpace to look through pointer vectorsChandler Carruth
politely and document this feature. This simple API extension then allows us to write all of the Instructions' address space query methods much more simply. No functionality change intended here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167223 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-01Revert the series of commits starting with r166578 which introduced theChandler Carruth
getIntPtrType support for multiple address spaces via a pointer type, and also introduced a crasher bug in the constant folder reported in PR14233. These commits also contained several problems that should really be addressed before they are re-committed. I have avoided reverting various cleanups to the DataLayout APIs that are reasonable to have moving forward in order to reduce the amount of churn, and minimize the number of commits that were reverted. I've also manually updated merge conflicts and manually arranged for the getIntPtrType function to stay in DataLayout and to be defined in a plausible way after this revert. Thanks to Duncan for working through this exact strategy with me, and Nick Lewycky for tracking down the really annoying crasher this triggered. (Test case to follow in its own commit.) After discussing with Duncan extensively, and based on a note from Micah, I'm going to continue to back out some more of the more problematic patches in this series in order to ensure we go into the LLVM 3.2 branch with a reasonable story here. I'll send a note to llvmdev explaining what's going on and why. Summary of reverted revisions: r166634: Fix a compiler warning with an unused variable. r166607: Add some cleanup to the DataLayout changes requested by Chandler. r166596: Revert "Back out r166591, not sure why this made it through since I cancelled the command.

2012-10-29Remove a wrapper around getIntPtrType added to GVN by Hal in commit 166624 (theDuncan Sands
wrapper returns a vector of integers when passed a vector of pointers) by having getIntPtrType itself return a vector of integers in this case. Outside of this wrapper, I didn't find anywhere in the codebase that was relying on the old behaviour for vectors of pointers, so give this a whirl through the buildbots. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166939 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-24Fix ODR violations: a virtual function must be defined, even if it's neverRichard Smith
called. Provide an (asserting) definition of Operator's private destructor. Remove destructors from all classes derived from Operator. We don't need them for safety, because their implicit definitions would be ill-formed (they'd call Operator's private destructor), and we don't need them to avoid emitting vtables, because we don't do anything with Operator subclasses which would trigger vtable instantiation. The Operator hierarchy is still a complete disaster with regard to undefined behavior, but this at least allows LLVM to link when using Clang's -fcatch-undefined-behavior with a new vptr-based type checking mechanism. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166530 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-21DataLayout should use itself when calculating the size of a vector.Hal Finkel
This is important for vectors of pointers because only DataLayout, not the underlying vector type, knows how to calculate the size of the pointers in the vector. Fixes PR14138. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166401 91177308-0d34-0410-b5e6-96231b3b80d8
