* Fix a race condition in support library ThreadPool.Justin Lebar2016-04-061-1/+4
| | | | | | | | | | | | | | | By running TSAN on the ThreadPool unit tests it was discovered that the threads in the pool can pop tasks off the queue at the same time the "wait" routine is trying to check if the task queue is empty. This patch fixes this problem by checking for active threads in the waiter before checking whether the queue is empty. Patch by Jason Henline.

* Add Cache Pruning supportMehdi Amini2016-04-022-0/+131
| | | | | | | | | | | | | | | | | | | | Incremental LTO will usea cache to store object files. This patch handles the pruning part of the cache, exposing a few knobs: - Pruning interval: the implementation keeps a "timestamp" file in the directory and will scan it only after a given interval since the last modification of the timestamp file. This is for performance purpose, we don't want to scan continuously the folder. - Entry expiration: this is the time after which a file that hasn't been used is remove from the cache. - Maximum size: expressed in percentage of the available disk space, it helps to avoid that we blow up the disk space. http://reviews.llvm.org/D18422 From: Mehdi Amini <mehdi.amini@apple.com> llvm-svn: 265209

* Support: Implement StreamingMemoryObject::getPointerDuncan P. N. Exon Smith2016-03-271-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | The implementation is fairly obvious. This is preparation for using some blobs in bitcode. For clarity (and perhaps future-proofing?), I moved the call to JumpToBit in BitstreamCursor::readRecord ahead of calling MemoryObject::getPointer, since JumpToBit can theoretically (a) read bytes, which (b) invalidates the blob pointer. This isn't strictly necessary the two memory objects we have: - The return of RawMemoryObject::getPointer is valid until the memory object is destroyed. - StreamingMemoryObject::getPointer is valid until the next chunk is read from the stream. Since the JumpToBit call is only going ahead to a word boundary, we'll never load another chunk. However, reordering makes it clear by inspection that the blob returned by BitstreamCursor::readRecord will be valid. I added some tests for StreamingMemoryObject::getPointer and BitstreamCursor::readRecord. llvm-svn: 264549

| | | | | | | This reverts commit r264409 since it failed to bootstrap: http://lab.llvm.org:8080/green/job/clang-stage2-configure-Rlto_build/8302/ llvm-svn: 264410
* Bitcode: Collect all MDString records into a single blobDuncan P. N. Exon Smith2016-03-251-0/+6
| | | | | | | | | | | | | | | | | | | | | | | Optimize output of MDStrings in bitcode. This emits them in big blocks (currently 1024) in a pair of records: - BULK_STRING_SIZES: the sizes of the strings in the block, and - BULK_STRING_DATA: a single blob, which is the concatenation of all the strings. Inspired by Mehdi's similar patch, http://reviews.llvm.org/D18342, this should (a) slightly reduce bitcode size, since there is less record overhead, and (b) greatly improve reading speed, since blobs are super cheap to deserialize. I needed to add support for blobs to streaming input to get the test suite passing. - StreamingMemoryObject::getPointer reads ahead and returns the address of the blob. - To avoid a possible reallocation of StreamingMemoryObject::Bytes, BitstreamCursor::readRecord needs to move the call to JumpToEnd forward so that getPointer is the last bitstream operation. llvm-svn: 264409

* Adjust initial size in StringMap constructor to guarantee no grow()Mehdi Amini2016-03-251-1/+15
| | | | | | | | | | | | | | | | | | Summary: StringMap ctor accepts an initialize size, but expect it to be rounded to the next power of 2. The ctor can handle that directly instead of expecting clients to round it. Also, since the map will resize itself when 75% full, take this into account an initialize a larger initial size to avoid any growth.

* [Support] Make all Errors convertible to std::error_code.Lang Hames2016-03-233-3/+46
| | | | | | | | | | | | This is a temporary crutch to enable code that currently uses std::error_code to be incrementally moved over to Error. Requiring all Error instances be convertible enables clients to call errorToErrorCode on any error (not just ECErrors created by conversion *from* an error_code). This patch also moves code for Error from ErrorHandling.cpp into a new Error.cpp file. llvm-svn: 264221

* [Support] Add the 'Error' class for structured error handling.Lang Hames2016-03-161-0/+4
| | | | | | | | | | | | | | | | | This patch introduces the Error classs for lightweight, structured, recoverable error handling. It includes utilities for creating, manipulating and handling errors. The scheme is similar to exceptions, in that errors are described with user-defined types. Unlike exceptions however, errors are represented as ordinary return types in the API (similar to the way std::error_code is used). For usage notes see the LLVM programmer's manual, and the Error.h header. Usage examples can be found in unittests/Support/ErrorTest.cpp. Many thanks to David Blaikie, Mehdi Amini, Kevin Enderby and others on the llvm-dev and llvm-commits lists for lots of discussion and review. llvm-svn: 263609

* More UTF string conversion wrappersMarianne Mailhot-Sarrasin2016-03-112-2/+98
| | | | | | | | | | | Added new string conversion wrappers that convert between `std::string` (of UTF-8 bytes) and `std::wstring`, which is particularly useful for Win32 interop. Also fixed a missing string conversion for `getenv` on Win32, using these new wrappers. The motivation behind this is to provide the support functions required for LLDB to work properly on Windows with non-ASCII data; however, the functions are not LLDB specific.
