2009-08-19raw_ostream: Remove pointless redefinitions of tell().Daniel Dunbar
- The base class implementation is correct. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79385 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-18raw_ostream: Add the capability for subclasses to manually install an externalDaniel Dunbar
buffer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79382 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-18raw_ostream: Reduce FormattedStream's reliance on raw_ostream's implementation.Daniel Dunbar
- Kill off begin(), end(), and iterator. It isn't clear what these mean. Instead provide getBufferStart(), which can be used with GetNumBytesInBuffer to the same effect. - Update ComputeColumn to take arguments for the buffer to scan, this simplifies the implementation of write_impl substantially. - This should also fix possible problems with the scanning pointer pointing outside of the current raw_ostream buffer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79379 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-18Revert r78924, disabling buffering defeats all the fast paths in raw_ostream.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79361 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-13Set raw_os_ostream, raw_string_ostream, and raw_svector_ostream to beDan Gohman
unbuffered. std::ostream does its own buffering, and std::string and SmallVector both have allocation strategies intended to handle frequent appending. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78924 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-13Add support to raw_ostream for sizing the buffer according to theDan Gohman
needs of the underlying output mechanism. raw_fd_ostream now uses st_blksize from fstat to determine a buffer size. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78923 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-13Make raw_ostream non-copyable.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78920 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-13Move SetBufferSize and SetUnbuffered out of line.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78909 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-13Fix the buffer handling logic so that write_impl is always called withDan Gohman
a full buffer, rather than often being called with a slightly-less-than-full buffer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78907 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-12Add a GetBufferSize() member to raw_ostream and use it toDan Gohman
simplify some formatted_raw_ostream code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78836 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-30Add raw_ostream::write_hexDaniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77614 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-28Add some protected interfaces to allow subclass access to the buffer.David Greene
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77395 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-27Make raw_null_ostream flush its buffer in its destructor, so thatDan Gohman
it conforms to the assertion added in r77245. This fixes a failure in qa_override.c in clang's testsuite. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77255 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-22Support writing a StringRef to a raw_ostream directly.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76754 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-16Add raw_null_ostream and llvm::nulls(), a raw_ostream that discards output.Daniel Dunbar
- No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76103 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-16Add explicit keywords.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76073 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-16Use size_t.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76069 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-15Change raw_ostream so that it doesn't call llvm_report_errorDan Gohman
immediately on every output error. Instead, add a flag to raw_ostream, and set the flag whenever an error is detected. The flag can be queried and cleared from the public API. This gives applications more flexibility to handling errors in application-specific ways. If the flag is not cleared when the raw_ostream is destructed, llvm_report_error is called from the destructor. This ensures that errors are not implicitly silenced, and provides convenient default behavior for tools like llc and opt. Clients wishing to avoid llvm_report_error calls from raw_ostream should check for errors and clear the error flag. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75857 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-15Fix a thinko in a comment that Duncan spotted.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75803 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-15Add a Force option to raw_fd_ostream to specify whether openingDan Gohman
an existing file is considered an error. Convert several tools to use raw_fd_ostream instead of std::ostream, and to use this new option instead of doing a manual check. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75801 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-15Add a comment noting that raw_os_ostream does not check for errors.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75794 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-10Make changes suggested by Chris and eliminate newly-added raw_ostreamDavid Greene
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75283 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-09Add some hooks that a redesigned AsmStream needs to do its job. TheseDavid Greene
allow derived classes to examine the stream buffer before it's flushed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75199 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-04Add support for outputting ANSI colors to raw_fd_ostream.Torok Edwin
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72854 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-20Make all raw_ostreams support the tell() function.Douglas Gregor
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69583 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-03Add fast path for raw_ostream output of strings.Daniel Dunbar
- Particularly nice for small constant strings, which get optimized down nicely. On a synthetic benchmark writing out "hello" in a loop, this is about 2x faster with gcc and 3x faster with llvm-gcc. llc on insn-attrtab.bc from 403.gcc is about .5% faster. - I tried for a fancier solution which wouldn't increase code size as much (by trying to match constant arrays), but can't quite make it fly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68396 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-17raw_ostream: Return '*this' explicitly (instead of implicitly viaDaniel Dunbar
write) to expose more alias information. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@67070 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-17raw_ostream: Rework implementation of unbuffered streams so outputtingDaniel Dunbar
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@67066 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-16raw_ostream: Replace flush_impl with write_impl, which takes data toDaniel Dunbar
write as arguments. - Add raw_ostream::GetNumBytesInBuffer. - Privatize buffer pointers. - Get rid of slow and unnecessary code for writing out large strings. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@67060 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-16raw_ostream: Lift out flush_nonempty.Daniel Dunbar
- 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?). - 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@67057 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-10PR3478: raw_ostream should not buffer stderrDaniel Dunbar
- Add unbuffered flag to raw_ostream, forwarded by raw_fd_ostream and used by raw_stderr_ostream. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66545 91177308-0d34-0410-b5e6-96231b3b80d8

2008-08-26Added "str()" method to raw_string_ostream.Ted Kremenek
str() mirrors the same method in std::ostringstream. str() flushes the buffered stream contents to string and returns a reference to the string. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55370 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-23Add raw_stream adaptors that write into an std::string and ↵Chris Lattner
SmallVector/SmallString. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55265 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-23Switch the asmprinter (.ll) and all the stuff it requires over toChris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55263 91177308-0d34-0410-b5e6-96231b3b80d8
