and Mach-O systems. Additionally, correct the Mach-O logic code to look at
byte 12 not byte 15. Hopefully this fixes the llvm-ld warning on Darwin.

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.

* 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.

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

Final commit for this bug. This removes the last EH holdouts in LLVM
and turns off exception support by using the -fno-exceptions option. This
leads to the following reduction in library and executable sizes:

Adjust implementation to match the new interface after exception handling
was removed in the Unix verison. NOTE: this hasn't been compiled yet!

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.

Update ltld.[ch] to version 1.5.22.
Correct the notes about updating these tools (autoconf/README.TXT)
Add configure options for getting the correct option for including a whole
archive when linking.

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.

Put the rest of lib/System into LinkAllVMCore.h. This makes all of
lib/System available to programs that #include LinkALlVMCore.h so that
loadable modules linked into those programs can depend on all of lib/System
being available.

1. Move IncludeFile.h to System library
2. Move IncludeFile.cpp to System library
3. #1 and #2 required to prevent cyclic library dependencies for libSystem
4. Convert all existing uses of Support/IncludeFile.h to System/IncludeFile.h
5. Add IncludeFile support to various lib/System classes.
6. Add new lib/System classes to LinkAllVMCore.h
All this in an attempt to pull in lib/System to what's required for VMCore

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.
llvm-svn: 28810
Change the file size field of StatusInfo to be uint64_t instead of size_t
so that we know it is always 64 bits. This prevents some overflow on
systems where size_t is 32 bits when it ought to be 64.
llvm-svn: 28726
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.
Patch Contributed by Michael Smith.
llvm-svn: 28722
Break the "IncludeFile" mechanism into its own header file and adjust other
files accordingly. Use this facility for the IntrinsicInst problem which
was the subject of PR800.
More to follow on this.
llvm-svn: 28709
Turn -pedantic and -Wno-long-long compile flags on by default. In a few
places, avoid the warnings by removing these options in the local makefile.
One notable exception: lib/Target/CBackend/Writer.cpp. These warnings are
left on as a reminder to developers to clean them up.
