* Go bindings: make various DIBuilder arguments optional.Peter Collingbourne2015-04-081-15/+19
| | | | | | | | | | | r234262 changed some code in DIBuilderBindings.cpp to use the unwrap function to unwrap debug metadata. The problem with this is that unwrap asserts that its argument is non-null, which is not what we want in a number of places in DIBuilder where the argument is optional. This change makes certain arguments optional by adding null checks in places where it is required, fixing the llgo build. llvm-svn: 234428
* IR: Remove MDTupleTypedArrayWrapper::operator MDTuple*()Duncan P. N. Exon Smith2015-04-071-2/+2
| | | | | | | | | | | | Remove `MDTupleTypedArrayWrapper::operator MDTuple*()`, since it causes ambiguity (at least in some [1] compilers [2]) when using indexes to `MDTupleTypedArrayWrapper::operator[](unsigned)` that are convertible to (but not the same as) `unsigned`.

* [PM] Remove the old 'PassManager.h' header file at the top level ofChandler Carruth2015-02-131-1/+1
| | | | | | | | | | | | | | | | | | | | LLVM's include tree and the use of using declarations to hide the 'legacy' namespace for the old pass manager. This undoes the primary modules-hostile change I made to keep out-of-tree targets building. I sent an email inquiring about whether this would be reasonable to do at this phase and people seemed fine with it, so making it a reality. This should allow us to start bootstrapping with modules to a certain extent along with making it easier to mix and match headers in general. The updates to any code for users of LLVM are very mechanical. Switch from including "llvm/PassManager.h" to "llvm/IR/LegacyPassManager.h". Qualify the types which now produce compile errors with "legacy::". The most common ones are "PassManager", "PassManagerBase", and "FunctionPassManager". llvm-svn: 229094

* SpecialCaseList: Add support for parsing multiple input files.Alexey Samsonov2015-02-043-8/+16
| | | | | | | | | | | | | | | | | | | | | | | Summary: This change allows users to create SpecialCaseList objects from multiple local files. This is needed to implement a proper support for -fsanitize-blacklist flag (allow users to specify multiple blacklists, in addition to default blacklist, see PR22431). DFSan can also benefit from this change, as DFSan instrumentation pass now accepts ABI-lists both from -fsanitize-blacklist= and -mllvm -dfsan-abilist flags. Go bindings are fixed accordingly.

* IR: Return unique_ptr from MDNode::getTemporary()Duncan P. N. Exon Smith2015-01-191-2/+3
| | | | | | | | | | | | Change `MDTuple::getTemporary()` and `MDLocation::getTemporary()` to return (effectively) `std::unique_ptr<T, MDNode::deleteTemporary>`, and clean up call sites. (For now, `DIBuilder` call sites just call `release()` immediately.) There's an accompanying change in each of clang and polly to use the new API. llvm-svn: 226504
* IR: Remove MDNodeFwdDeclDuncan P. N. Exon Smith2015-01-191-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove `MDNodeFwdDecl` (as promised in r226481). Aside from API changes, there's no real functionality change here. `MDNode::getTemporary()` now forwards to `MDTuple::getTemporary()`, which returns a tuple with `isTemporary()` equal to true. The main point is that we can now add temporaries of other `MDNode` subclasses, needed for PR22235 (I introduced `MDNodeFwdDecl` in the first place because I didn't recognize this need, and thought they were only needed to handle forward references). A few things left out of (or highlighted by) this commit: - I've had to remove the (few) uses of `std::unique_ptr<>` to deal with temporaries, since the destructor is no longer public. `getTemporary()` should probably return the equivalent of `std::unique_ptr<T, MDNode::deleteTemporary>`. - `MDLocation::getTemporary()` doesn't exist yet (worse, it actually does exist, but does the wrong thing: `MDNode::getTemporary()` is inherited and returns an `MDTuple`). - `MDNode` now only has one subclass, `UniquableMDNode`, and the distinction between them is actually somewhat confusing. I'll fix those up next. llvm-svn: 226501

* IR: Split Metadata from ValueDuncan P. N. Exon Smith2014-12-091-24/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Split `Metadata` away from the `Value` class hierarchy, as part of PR21532. Assembly and bitcode changes are in the wings, but this is the bulk of the change for the IR C++ API. I have a follow-up patch prepared for `clang`. If this breaks other sub-projects, I apologize in advance :(. Help me compile it on Darwin I'll try to fix it. FWIW, the errors should be easy to fix, so it may be simpler to just fix it yourself. This breaks the build for all metadata-related code that's out-of-tree. Rest assured the transition is mechanical and the compiler should catch almost all of the problems. Here's a quick guide for updating your code: - `Metadata` is the root of a class hierarchy with three main classes: `MDNode`, `MDString`, and `ValueAsMetadata`. It is distinct from the `Value` class hierarchy. It is typeless -- i.e., instances do *not* have a `Type`. - `MDNode`'s operands are all `Metadata *` (instead of `Value *`). - `TrackingVH<MDNode>` and `WeakVH` referring to metadata can be replaced with `TrackingMDNodeRef` and `TrackingMDRef`, respectively. If you're referring solely to resolved `MDNode`s -- post graph construction -- just use `MDNode*`. - `MDNode` (and the rest of `Metadata`) have only limited support for `replaceAllUsesWith()`. As long as an `MDNode` is pointing at a forward declaration -- the result of `MDNode::getTemporary()` -- it maintains a side map of its uses and can RAUW itself. Once the forward declarations are fully resolved RAUW support is dropped on the ground. This means that uniquing collisions on changing operands cause nodes to become "distinct". (This already happened fairly commonly, whenever an operand went to null.) If you're constructing complex (non self-reference) `MDNode` cycles, you need to call `MDNode::resolveCycles()` on each node (or on a top-level node that somehow references all of the nodes). Also, don't do that. Metadata cycles (and the RAUW machinery needed to construct them) are expensive. - An `MDNode` can only refer to a `Constant` through a bridge called `ConstantAsMetadata` (one of the subclasses of `ValueAsMetadata`). As a side effect, accessing an operand of an `MDNode` that is known to be, e.g., `ConstantInt`, takes three steps: first, cast from `Metadata` to `ConstantAsMetadata`; second, extract the `Constant`; third, cast down to `ConstantInt`. The eventual goal is to introduce `MDInt`/`MDFloat`/etc. and have metadata schema owners transition away from using `Constant`s when the type isn't important (and they don't care about referring to `GlobalValue`s). In the meantime, I've added transitional API to the `mdconst` namespace that matches semantics with the old code, in order to avoid adding the error-prone three-step equivalent to every call site. If your old code was: MDNode *N = foo(); bar(isa <ConstantInt>(N->getOperand(0))); baz(cast <ConstantInt>(N->getOperand(1))); bak(cast_or_null <ConstantInt>(N->getOperand(2))); bat(dyn_cast <ConstantInt>(N->getOperand(3))); bay(dyn_cast_or_null<ConstantInt>(N->getOperand(4))); you can trivially match its semantics with: MDNode *N = foo(); bar(mdconst::hasa <ConstantInt>(N->getOperand(0))); baz(mdconst::extract <ConstantInt>(N->getOperand(1))); bak(mdconst::extract_or_null <ConstantInt>(N->getOperand(2))); bat(mdconst::dyn_extract <ConstantInt>(N->getOperand(3))); bay(mdconst::dyn_extract_or_null<ConstantInt>(N->getOperand(4))); and when you transition your metadata schema to `MDInt`: MDNode *N = foo(); bar(isa <MDInt>(N->getOperand(0))); baz(cast <MDInt>(N->getOperand(1))); bak(cast_or_null <MDInt>(N->getOperand(2))); bat(dyn_cast <MDInt>(N->getOperand(3))); bay(dyn_cast_or_null<MDInt>(N->getOperand(4))); - A `CallInst` -- specifically, intrinsic instructions -- can refer to metadata through a bridge called `MetadataAsValue`. This is a subclass of `Value` where `getType()->isMetadataTy()`. `MetadataAsValue` is the *only* class that can legally refer to a `LocalAsMetadata`, which is a bridged form of non-`Constant` values like `Argument` and `Instruction`. It can also refer to any other `Metadata` subclass. (I'll break all your testcases in a follow-up commit, when I propagate this change to assembly.) llvm-svn: 223802
