methods that were recently added to the interface.

Standardize the error messages to be in "path: what failed: why" format.
Also attempt to use the correct errno to ThrowErrno in situations where
the errno value is erased by subsequent system calls.

llvm-svn: 21385

Allow the ThrowErrno function to optionally accept an error number
parameter so that callers can specify the error number to be used.

result in returning executable files that won't be runnable.

* Ensure #includes are wrapped with appropriate HAVE_ guards
* Account for variations in time.h and sys/time.h inclusion.
* Add macros for getting wait(2) exit status correctly (per autoconf sugg.)
* Implement ThrowErrno in terms of strerror_r, strerror or none based on
  what is available on the platform.

llvm-svn: 19161

* Remove redundant #includes that are now in Unix.h

llvm-svn: 19160

* Move implementation of sys::PreventCoreFiles function to this file from
  the now defunct SysConfig abstraction.

llvm-svn: 19159

* Ensure #includes are wrapped with appropriate HAVE_ guards
* Ensure variations in "dirent" structure are accounted for.

llvm-svn: 19158

* Ensure #includes are wrapped with appropriate HAVE_ guards
* Consolidate implementation from operating system specific directory.

SysConf abstraction was pointless because it had a single function in it that
pertained only to the current process. So merge it into the Process abstraction
and remove the files completely.

llvm-svn: 19149

Merge implementations of isValid and GetTemporaryDirectory into this file. There
is not any point having the operating system specific files for such little
variation between the Unix family of systems.

* Implement GetMallocUsage to get usage of malloc heap
* Implement GetMemoryUsage to get total memory usage of process
* Implement GetTimeUsage to get elapsed/user/system time

* llvm/Config/alloca.h already #includes config.h

Move the functionality of RunProgramWithTimeout into the ExecuteAndWait
function: support a timeout and I/O redirects

Add a needed include.

const because they affect the file system, not the Path object.

because LLVM should be agnostic to the needs of specific front ends.
