Make the Win32 code exception free (untested/uncompiled) which forced some interface changes which had ripple effect. This should be the last of 797. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29884 91177308-0d34-0410-b5e6-96231b3b80d8

Make sys::Program::ExecuteAndWait not throw exceptions and update any affected code. It now return -9999 to signal that the program couldn't be executed. Only one case (in bugpoint) actually examines the result code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29785 91177308-0d34-0410-b5e6-96231b3b80d8
2006-08-07Remove extraneous #include.Reid Spencer
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29541 91177308-0d34-0410-b5e6-96231b3b80d8
2006-08-07Make the removal of files use Path::eraseFromDisk just like it does forReid Spencer
the removal of directories. Using std::remove is indiscriminate and can lead to the removal of things like /dev/null if run as root. The Path::eraseFromDisk method ensures that we only ever remove regular files or directories, but never character or block special nodes. This should clear up the problem with usage like: llvm-as -o /dev/null which is used in the llvm-test makefiles. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29540 91177308-0d34-0410-b5e6-96231b3b80d8
2006-08-07Add a note about how the "isFile" check in Path::eraseFromDisk preventsReid Spencer
the erasure of non-file paths like /dev/null. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29539 91177308-0d34-0410-b5e6-96231b3b80d8

2006-07-28Change Path::getStatusInfo to return a boolean and error string on an errorChris Lattner
instead of throwing an exception. This reduces the amount of code that is exposed to exceptions (e.g. FileUtilities), though it is clearly only one step along the way. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29395 91177308-0d34-0410-b5e6-96231b3b80d8

2006-06-16Only print the stack trace if it was requested. Previously, any call intoReid Spencer
the Signals module that registered the handlers would cause the stack trace to be generated. Now, you must explicitly call PrintStackTraceOnErrorSignal in order for that to happen. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28810 91177308-0d34-0410-b5e6-96231b3b80d8

2006-06-07For PR787:Reid Spencer
Provide new llvm::sys::Program facilities for converting the stdout and stdin to binary mode. There is no standard way to do this and the available mechanisms are platform specific. Adjust the bytecode reader and writer to use these methods when their input is stdin or output is stdout. THis avoids the problem with \n writing CRLF to a bytecode file on windows.

2005-07-12For PR540:Reid Spencer
Add a Mutex class for thread synchronization in a platform-independent way. The current implementation only supports pthreads. Win32 use of Critical Sections will be added later. The design permits other threading models to be used if (and only if) pthreads is not available. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22403 91177308-0d34-0410-b5e6-96231b3b80d8

2005-07-08Two changes:Reid Spencer
1. Use isValid() to check validity of the resulting path name in the eraseSuffix even though we can't think of a case where eraseSuffix could possibly cause an invalid path name. 2. Rewrite isValid() to not use the deprecated realpath function any more. It now just uses isascii to make sure all the characters are legit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22359 91177308-0d34-0410-b5e6-96231b3b80d8
