* [Modules] Move the LeakDetector header into the IR library where theChandler Carruth2014-03-04
| | | | | | | | | | | source file had already been moved. Also move the unittest into the IR unittest library. This may seem an odd thing to put in the IR library but we only really use this with instructions and it needs the LLVM context to work, so it is intrinsically tied to the IR library. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@202842 91177308-0d34-0410-b5e6-96231b3b80d8
* [Modules] Move the ConstantRange class into the IR library. This isChandler Carruth2014-03-04
| | | | | | | | | | a bit surprising, as the class is almost entirely abstracted away from any particular IR, however it encodes the comparsion predicates which mutate ranges as ICmp predicate codes. This is reasonable as they're used for both instructions and constants. Thus, it belongs in the IR library with instructions and constants. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@202838 91177308-0d34-0410-b5e6-96231b3b80d8

* [Modules] Move ValueMap to the IR library. While this class does notChandler Carruth2014-03-04
| | | | | | | | | | | | directly care about the Value class (it is templated so that the key can be any arbitrary Value subclass), it is in fact concretely tied to the Value class through the ValueHandle's CallbackVH interface which relies on the key type being some Value subclass to establish the value handle chain. Ironically, the unittest is already in the right library. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@202824 91177308-0d34-0410-b5e6-96231b3b80d8
* [Modules] Move ValueHandle into the IR library where Value itself lives.Chandler Carruth2014-03-04
| | | | | | | | | | | Move the test for this class into the IR unittests as well. This uncovers that ValueMap too is in the IR library. Ironically, the unittest for ValueMap is useless in the Support library (honestly, so was the ValueHandle test) and so it already lives in the IR unittests. Mmmm, tasty layering. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@202821 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix resetting the DataLayout in a Module.Rafael Espindola2014-02-25
| | | | | | | | | | | | | | | No tool does this currently, but as everything else in a module we should be able to change its DataLayout. Most of the fix is in DataLayout to make sure it can be reset properly. The test uses Module::setDataLayout since the fact that we mutate a DataLayout is an implementation detail. The module could hold a OwningPtr<DataLayout> and the DataLayout itself could be immutable. Thanks to Philip Reames for pushing me in the right direction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@202198 91177308-0d34-0410-b5e6-96231b3b80d8

* Simplify remove, create_directory and create_directories.Rafael Espindola2014-02-23
| | | | | | | | | | | | | | | Before this patch they would take an boolean argument to say if the path already existed. This was redundant with the returned error_code which is able to represent that. This allowed for callers to incorrectly check only the existed flag instead of first checking the error code. Instead, pass in a boolean flag to say if the previous (non-)existence should be an error or not. Callers of the of the old simple versions are not affected. They still ignore the previous (non-)existence as they did before. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201979 91177308-0d34-0410-b5e6-96231b3b80d8

* Stackmaps are used for OSR exits, which is a custom kind of unwinding. ↵Filip Pizlo2014-02-20
| | | | | | | | | | | | | | | | | | | Hence, they should not be marked nounwind. Marking them nounwind caused crashes in the WebKit FTL JIT, because if we enable sufficient optimizations, LLVM starts eliding compact_unwind sections (or any unwind data for that matter), making deoptimization via stackmaps impossible. This changes the stackmap intrinsic to be may-throw, adds a test for exactly the sympton that WebKit saw, and fixes TableGen to handle un-attributed intrinsics.

| | | | | | | | | | | | | passing down an AsmPrinter instance so we could compute the size of the block which could be target specific. All of the test cases in the unittest don't have any target specific data so we can use a NULL AsmPrinter there. This also depends upon block data being added as integers.

* Introduce line editor library.Peter Collingbourne2014-01-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | This library will be used by clang-query. I can imagine LLDB becoming another client of this library, so I think LLVM is a sensible place for it to live. It wraps libedit, and adds tab completion support. The code is loosely based on the line editor bits in LLDB, with a few improvements: - Polymorphism for retrieving the list of tab completions, based on the concept pattern from the new pass manager. - Tab completion doesn't corrupt terminal output if the input covers multiple lines. Unfortunately this can only be done in a truly horrible way, as far as I can tell. But since the alternative is to implement our own line editor (which I don't think LLVM should be in the business of doing, at least for now) I think it may be acceptable. - Includes a fallback for the case where the user doesn't have libedit installed. Note that this uses C stdio, mainly because libedit also uses C stdio.
