* Add line tracking support to FormattedStream Daniel Malea2013-05-08
| | | | | | | | | | - previously formatted_raw_ostream tracked columns, now it tracks lines too - used by (upcoming) DebugIR pass to know the line number to connect to each IR instruction git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181463 91177308-0d34-0410-b5e6-96231b3b80d8

* formatted_raw_ostream: Fix a serious bug in tell().Daniel Dunbar2012-09-14
| | | | | | | | | - The current_pos function is supposed to return all the written bytes, not the current position of the underlying stream. - This caused tell() to be broken whenever the underlying stream had buffered content. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163948 91177308-0d34-0410-b5e6-96231b3b80d8

* Make some methods const. The only interesting change here is thatChris Lattner2009-12-19
| | | | | | | | | | it changes raw_fd_ostream::preferred_buffer_size to return zero on a scary stat failure instead of setting the stream to an error state. This method really should not mutate the stream. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@91740 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | buffer", while we work out a solution. Dan convinced me that making debugging annoying for him is worse than 10x being slower for me. :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82553 91177308-0d34-0410-b5e6-96231b3b80d8
* Don't allow formatted_ostream to be unbuffered, even if its underlying bufferDaniel Dunbar2009-09-21
| | | | | | | | | | | | is. - The problem is that formatted_ostream forces its underlying buffer to be unbuffered, so if some client happens to wrap a formatted_ostream around something, but still use the underlying stream, then we can end up writing on a fully unbuffered output (which was never intended to be unbuffered). - This makes clang (and presumably llvm-gcc) -emit-llvm -S a mere 10x faster. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82434 91177308-0d34-0410-b5e6-96231b3b80d8

* raw_ostream: Reduce FormattedStream's reliance on raw_ostream's implementation.Daniel Dunbar2009-08-18
| | | | | | | | | | | | | | | - 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

* formatted_raw_ostream both is-a raw_ostream and has-a raw_ostream. ThisDan Gohman2009-07-16
| | | | | | | | | | | | | | | | means that two separate raw_ostreams are doing buffering before data is sent to the underlying stream. Besides the inefficiency of redundant buffering, the second level of buffering doesn't recieve flush() requests. Fix this by having formatted_raw_ostream set the underlying raw_ostream to be unbuffered. This eliminates inefficiency due to redundant buffering, and it makes the flush() disconnect harmless. This fixes PR4559. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75883 91177308-0d34-0410-b5e6-96231b3b80d8
