* 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

| | | | | | | | | | | | | | | | | | | | | | | | | | division and make the private scale in BlockFrequency more performant. This change is the first in a series of changes improving LLVM's Block Frequency propogation implementation to not lose probability mass in branchy code when propogating block frequency information from a basic block to its successors. This patch is a simple infrastructure improvement that does not actually modify the block frequency algorithm. The specific changes are: 1. Changes the division algorithm used when scaling block frequencies by branch probabilities to a short division algorithm. This gives us the remainder for free as well as provides a nice speed boost. When I benched the old routine and the new routine on a Sandy Bridge iMac with disabled turbo mode performing 8192 iterations on an array of length 32768, I saw ~600% increase in speed in mean/median performance. 2. Exposes a scale method that returns a remainder. This is important so we can ensure that when we scale a block frequency by some branch probability BP = N/D, the remainder from the division by D can be retrieved and propagated to other children to ensure no probability mass is lost (more to come on this). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194950 91177308-0d34-0410-b5e6-96231b3b80d8

* Simplify ErrorOr.Rafael Espindola2013-11-05
| | | | | | | | | | | | | | | | ErrorOr had quiet a bit of complexity and indirection to be able to hold a user type with the error. That feature is not used anymore. This patch removes it, it will live in svn history if we ever need it again. If we do need it again, IMHO there is one thing that should be done differently: Holding extra info in the error is not a property a function also returning a value or not. The ability to hold extra info should be in the error type and ErrorOr templated over it so that we don't need the funny looking ErrorOr<void>. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194030 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | - New ProcessInfo class to encapsulate information about child processes. - Generalized the Wait() to support non-blocking wait on child processes. - ExecuteNoWait() now returns a ProcessInfo object with information about the launched child. Users will be able to use this object to perform non-blocking wait. - ExecuteNoWait() now accepts an ExecutionFailed param that tells if execution failed or not. These changes will allow users to implement basic process parallel tools.

* Add getenv() wrapper that works on multibyte environment variable.Rui Ueyama2013-09-10
| | | | | | | | | | | | | | | | | | On Windows, character encoding of multibyte environment variable varies depending on settings. The only reliable way to handle it I think is to use GetEnvironmentVariableW(). GetEnvironmentVariableW() works on wchar_t string, which is on Windows UTF16 string. That's not ideal because we use UTF-8 as the internal encoding in LLVM. This patch defines a wrapper function which takes and returns UTF-8 string for GetEnvironmentVariableW(). The wrapper function does not do any conversion and just forwards the argument to getenv() on Unix.

| | | | | | | | | | | | | | | | | The work on this project was left in an unfinished and inconsistent state. Hopefully someone will eventually get a chance to implement this feature, but in the meantime, it is better to put things back the way the were.
