* Use the stat information in the Path object, if it is already obtained. ThisReid Spencer2007-03-291-4/+3
| | | | | | | avoids a call to ::fstat by MappedFile when the file size information was already obtained by the Path object. llvm-svn: 35477
* For PR789:Reid Spencer2007-03-292-34/+39
| | | | | | | | Make the sys::Path::getFileStatus function more efficient by having it return a pointer to the FileStatus structure rather than copy it. Adjust uses of the function accordingly. Also, fix some memory issues in sys::Path. llvm-svn: 35476
* Add a uniqueID field to the FileStatus structure for Paths. This will mapReid Spencer2007-03-291-0/+1

| | | | | | | | | * Add a method: bool isAbsolute() const, which determines if the path name is absolute or not. * Implement caching of file status information in the Path object. Allow it to be updated forcefully or lazily re-fetched from the cached value. llvm-svn: 35456

| | | | | | | Make the Win32 code exception free (untested/uncompiled) which forced some interface changes which had ripple effect. This should be the last of 797. llvm-svn: 29884

| | | | | | | Remove all exception code from Program.inc and implement its new interface with an ErrMsg string argument. llvm-svn: 29790
* For PR797:Reid Spencer2006-08-211-1/+1
| | | | | | | | 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. llvm-svn: 29785

* Make the removal of files use Path::eraseFromDisk just like it does forReid Spencer2006-08-071-4/+5
| | | | | | | | | | | 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. llvm-svn: 29540
