| | | | | | | | | | | | | | | | | | instead of custom status" No any changes, will follow up with D28807 commit containing APLi change for clang to fix build issues happened. Original commit message: [Support/Compression] - Change zlib API to return Error instead of custom status. Previously API returned custom enum values. Patch changes it to return Error with string description. That should help users to report errors in universal way. Differential revision: https://reviews.llvm.org/D28684 llvm-svn: 292226

* Define a dummy zlib::uncompress when zlib is not available.Rafael Espindola2016-09-121-0/+4

* Add a lower level zlib::uncompress.Rafael Espindola2016-09-091-6/+13
| | | | | | | | | | | SmallVectors are convenient, but they don't cover every use case. In particular, they are fairly large (3 pointers + one element) and there is no way to take ownership of the buffer to put it somewhere else. This patch then adds a lower lever interface that works with any buffer. llvm-svn: 281082

* [msan] Annotate zlib functions for MemorySanitizer.Evgeniy Stepanov2014-11-251-0/+6
| | | | | | | | | | | | | Mark destination buffer in zlib::compress and zlib::decompress as fully initialized. When building LLVM with system zlib and MemorySanitizer instrumentation, MSan does not observe memory writes in zlib code and erroneously considers zlib output buffers as uninitialized, resulting in false use-of-uninitialized memory reports. This change helps MSan understand the state of that memory and prevents such reports. llvm-svn: 222763

* Simplify compression API by decompressing into a SmallVector rather than a ↵David Blaikie2014-04-051-11/+6
| | | | | | | | | | | | MemoryBuffer This avoids an extra copy during decompression and avoids the use of MemoryBuffer which is a weirdly esoteric device that includes unrelated concepts like "file name" (its rather generic name is a bit misleading). Similar refactoring of zlib::compress coming up. llvm-svn: 205676
* Replace OwningPtr<T> with std::unique_ptr<T>.Ahmed Charles2014-03-061-7/+6
| | | | | | | | | | This compiles with no changes to clang/lld/lldb with MSVC and includes overloads to various functions which are used by those projects and llvm which have OwningPtr's as parameters. This should allow out of tree projects some time to move. There are also no changes to libs/Target, which should help out of tree targets have time to move, if necessary. llvm-svn: 203083
