Solaris 2.x does not have RLIMIT_RSS, check for this symbol (analog NetBSD below), should subsume Cygwin

Almost all occurrences of "bytecode" in the sources have been eliminated.

Implement the PathWithStatus class and its use throughout lib/System.

llvm-svn: 35742

avoids a call to ::fstat by MappedFile when the file size information was
already obtained by the Path object.

llvm-svn: 35477

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.

to the inode number on Unix and something far less unique on Windows. The
windows case needs to be improved.

llvm-svn: 35461

* 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.

the process in addition to disabling core file emission.  This speeds up
bugpoint on default-configured macs by several orders of magnitude.

llvm-svn: 30317

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

Final removal of exceptions from lib/System and adjustment of users to
accommodate.

llvm-svn: 29846

Eliminate exception throwing from Path::renamePathOnDisk and adjust its
users correspondingly.

llvm-svn: 29843

Remove exception throwing from Path::getDirectoryContents and its users.

llvm-svn: 29841

Remove exceptions from the Path::create*OnDisk methods. Update their users
to handle error messages via arguments and result codes.

llvm-svn: 29840

Change the Path::make*OnDisk methods exception free and adjust their usage.

llvm-svn: 29836

adjust users of it to compensate.

just return MinTime if that should ever happen.

llvm-svn: 29826

Make MappedFile not throw any exceptions.

llvm-svn: 29816

Fix a bug in my last patch that botched file redirection by using explicit
scoping of if statements.

llvm-svn: 29815

llvm-svn: 29808

Remove all exception code from Program.inc and implement its new interface
with an ErrMsg string argument.

llvm-svn: 29790

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.

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.
