* Update getLazyBitcodeModule to use ErrorOr for error handling.Rafael Espindola2014-01-13

* [PM] Split DominatorTree into a concrete analysis result object whichChandler Carruth2014-01-13
| | | | | | | | | | | | | | | | | | | | | | | can be used by both the new pass manager and the old. This removes it from any of the virtual mess of the pass interfaces and lets it derive cleanly from the DominatorTreeBase<> template. In turn, tons of boilerplate interface can be nuked and it turns into a very straightforward extension of the base DominatorTree interface. The old analysis pass is now a simple wrapper. The names and style of this split should match the split between CallGraph and CallGraphWrapperPass. All of the users of DominatorTree have been updated to match using many of the same tricks as with CallGraph. The goal is that the common type remains the resulting DominatorTree rather than the pass. This will make subsequent work toward the new pass manager significantly easier. Also in numerous places things became cleaner because I switched from re-running the pass (!!! mid way through some other passes run!!!) to directly recomputing the domtree. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199104 91177308-0d34-0410-b5e6-96231b3b80d8
* [cleanup] Move the Dominators.h and Verifier.h headers into the IRChandler Carruth2014-01-13
| | | | | | | | | | | | | | | | | | directory. These passes are already defined in the IR library, and it doesn't make any sense to have the headers in Analysis. Long term, I think there is going to be a much better way to divide these matters. The dominators code should be fully separated into the abstract graph algorithm and have that put in Support where it becomes obvious that evn Clang's CFGBlock's can use it. Then the verifier can manually construct dominance information from the Support-driven interface while the Analysis library can provide a pass which both caches, reconstructs, and supports a nice update API. But those are very long term, and so I don't want to leave the really confusing structure until that day arrives. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199082 91177308-0d34-0410-b5e6-96231b3b80d8

Rename the 'Assembly' include directory to 'AsmParser' to match the library name and the only functionality left their -- printing has been in the core IR library for quite some time. Update all of the #includes to match.

* Introduce a simple line-by-line iterator type into the Support library.Chandler Carruth2013-12-27
| | | | | | | | | | | | | | | | | | | This is an iterator which you can build around a MemoryBuffer. It will iterate through the non-empty, non-comment lines of the buffer as a forward iterator. It should be small and reasonably fast (although it could be made much faster if anyone cares, I don't really...). This will be used to more simply support the text-based sample profile file format, and is largely based on the original patch by Diego. I've re-worked the style of it and separated it from the work of producing a MemoryBuffer from a file which both simplifies the interface and makes it easier to test. The style of the API follows the C++ standard naming conventions to fit in better with iterators in general, much like the Path and FileSystem interfaces follow standard-based naming conventions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198068 91177308-0d34-0410-b5e6-96231b3b80d8

* Make sys::ThreadLocal<> zero-initialized on non-thread builds (PR18205)Hans Wennborg2013-12-19
| | | | | | | | | | | | | According to the docs, ThreadLocal<>::get() should return NULL if no object has been set. This patch makes that the case also for non-thread builds and adds a very basic unit test to check it. (This was causing PR18205 because PrettyStackTraceHead didn't get zero- initialized and we'd crash trying to read past the end of that list. We didn't notice this so much on Linux since we'd crash after printing all the entries, but on Mac we print into a SmallString, and would crash before printing that.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@197718 91177308-0d34-0410-b5e6-96231b3b80d8

* [asan] rewrite asan's stack frame layoutKostya Serebryany2013-12-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Rewrite asan's stack frame layout. First, most of the stack layout logic is moved into a separte file to make it more testable and (potentially) useful for other projects. Second, make the frames more compact by using adaptive redzones (smaller for small objects, larger for large objects). Third, try to minimized gaps due to large alignments (this is hypothetical since today we don't see many stack vars aligned by more than 32). The frames indeed become more compact, but I'll still need to run more benchmarks before committing, but I am sking for review now to get early feedback. This change will be accompanied by a trivial change in compiler-rt tests to match the new frame sizes.
