* For PR797:Reid Spencer2006-08-231-83/+75
| | | | | | | | Final remove of exception handling from this file. lib/System can no longer throw exceptions so there's no need for try/catch blocks here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29848 91177308-0d34-0410-b5e6-96231b3b80d8
* For PR797:Reid Spencer2006-08-221-6/+14
| | | | | | | | | | | Adjust users of MappedFile to its new non-throwing interface. Note that in most cases the lazy step of just throwing after a call to MappedFile was installed. This was done in the name of incremental changes. Getting rid of the new throw statements will take adjustment of interfaces and propagation of errors to higher levels. Those changes will come in subsequent patches. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29817 91177308-0d34-0410-b5e6-96231b3b80d8
* Change Path::getStatusInfo to return a boolean and error string on an errorChris Lattner2006-07-281-12/+16
| | | | | | | | | 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
* For PR777:Reid Spencer2006-05-151-0/+3
| | | | | | | | Add an additional catch block to ensure that this function can't throw any exceptions, even one's we're not expecting. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28309 91177308-0d34-0410-b5e6-96231b3b80d8

* Adjust DiffFilesWithTolerance to help poor cygwin's mmap facility byReid Spencer2005-02-151-8/+24
| | | | | | | | | | | handling zero length files a little more intelligently. If both files are zero length then we return 0 (true) indicating a match. If only one of the files is zero length then we return 1 (false) indicating that the files differ. If the files don't agree in length then they can't match so we skip the first loop that looks for a quick match. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20200 91177308-0d34-0410-b5e6-96231b3b80d8
