* Simplify ErrorOr.Rafael Espindola2013-11-051-38/+0
| | | | | | | | | | | | | | | | 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

* Add non-blocking Wait() for launched processesTareq A. Siraj2013-10-011-0/+103
| | | | | | | | | | | | | | | | | | - 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 Ueyama2013-09-101-0/+28
| | | | | | | | | | | | | | | | | | 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.

* Revert patches to add case-range support for PR1255.Bob Wilson2013-09-091-326/+0
| | | | | | | | | | | | | | | | | 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. I have left support in the bitcode reader to handle the case-range bitcode format, so that we do not lose bitcode compatibility with the llvm 3.3 release.

| | | | | | | | | | | | | | | | The main observation is that we never need both the filesize and the map size. When mapping a slice of a file, it doesn't make sense to request a null terminator and that would be the only case where the filesize would be used. There are other cleanups that should be done in this area: * A client should not have to pass the size (even an explicit -1) to say if it wants a null terminator or not, so we should probably swap the argument order. * The default should be to not require a null terminator. Very few clients require this, but many end up asking for it just because it is the default. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186984 91177308-0d34-0410-b5e6-96231b3b80d8
