Make changes suggested by Chris and eliminate newly-added raw_ostream
hooks as they're no longer needed.

The major change with this patch is to make formatted_raw_ostream usable
by any client of raw_ostream.

Add some hooks that a redesigned AsmStream needs to do its job. These
allow derived classes to examine the stream buffer before it's flushed.

llvm-svn: 75199

Add support for outputting ANSI colors to raw_fd_ostream.

llvm-svn: 72854

Make all raw_ostreams support the tell() function.

llvm-svn: 69583

Add BUILTIN_EXPECT Support/Compiler macro.
- Use for exceptional buffer conditions in raw_ostream:write to shave
off a cycle or two.

- Please rename if you have a better one.

llvm-svn: 67103

raw_ostream: Put all exceptional conditions in raw_ostream::write
under a single branch.

Also, add a FIXME for formatted output.

llvm-svn: 67069

raw_ostream: Rework implementation of unbuffered streams so outputting
a single character requires only one branch to follow slow path.
- Never use a buffer when writing on an unbuffered stream.

- Move default buffer size to header.

raw_ostream: Replace flush_impl with write_impl, which takes data to
write as arguments.
- Add raw_ostream::GetNumBytesInBuffer.
- Privatize buffer pointers.
- Get rid of slow and unnecessary code

raw_ostream: Lift out flush_nonempty.
- Flush a known non-empty buffers; enforces the interface to
flush_impl and kills off HandleFlush (which I saw no reason to be
an inline method, Chris?).

raw_ostream: Lift out flush_nonempty.
- Flush a known non-empty buffers; enforces the interface to
flush_impl and kills off HandleFlush (which I saw no reason to be

- Clarify invariant that flush_impl is only called with OutBufCur >
OutBufStart.

- This also cleary collects all places where we have to deal with the
buffer possibly not existing.

- A few more comments and fixing the unbuffered behavior remain in
this commit sequence.

Make raw_ostream::operator<<(const void *) fast; it doesn't matter but
it is easy.

llvm-svn: 67054

Add slow path for single character write, and use exclusively for
single characters writes outside of the fast path in raw_ostream.h

llvm-svn: 67053

PR3478: raw_ostream should not buffer stderr
- Add unbuffered flag to raw_ostream, forwarded by raw_fd_ostream and
used by raw_stderr_ostream.

llvm-svn: 66545

Add method raw_fd_ostream::seek() for random access within a file.

llvm-svn: 63044

Have raw_fd_ostream keep track of the position in the file to make tell() go faster by not requiring a flush().

llvm-svn: 60560

Add 'tell' method to raw_fd_ostream that clients can use to query the current location in the file the stream is writing to.

llvm-svn: 60085

Add Binary flag to raw_fd_ostream constructor.

Document raw_fd_ostream's treatment of "-".

llvm-svn: 59219

fix PR2953, an off-by-one error handling formatted i/o.
Thanks to Török Edwin for the awesome reduced testcase.

llvm-svn: 58199

Added raw_fd_ostream::close().

llvm-svn: 58052

Clear raw_fd_ostream error string on success and explain behavior in
documentation.

Add C++ header marker.

llvm-svn: 57923

Updating VC++ project.
Adding one include file and correct one declaration from class to struct in order to make llvm compile on VC2005.

llvm-svn: 55279

Add raw_stream adaptors that write into an std::string and SmallVector/SmallString.

Switch the asmprinter (.ll) and all the stuff it requires over to
use raw_ostream instead of std::ostream. Among other goodness,
this speeds up llvm-dis of kc++ with a release build from 0.85s
to 0.

Switch the asmprinter (.ll) and all the stuff it requires over to
use raw_ostream instead of std::ostream. Among other goodness,
this speeds up llvm-dis of kc++ with a release build from 0.85s
to 0.49s (88% faster).

Other interesting changes:
1) This makes Value::print be non-virtual.
2) AP[S]Int and ConstantRange can no longer print to ostream directly,
use raw_ostream instead.
3) This fixes a bug in raw_os_ostream where it didn't flush itself
when destroyed.
4) This adds a new SDNode::print method, instead of only allowing "dump".


A lot of APIs have both std::ostream and raw_ostream versions, it would
be useful to go through and systematically anihilate the std::ostream
versions.

This passes dejagnu, but there may be minor fallout, plz let me know if
so and I'll fix it.

add a simple mechanism for formatted output. This gives raw_ostream's
all the power and risk of fprintf format strings. Use them like this:

OS << format("%10.4f", 42.0) << "\n" << format("%x",
