* Switch to SmallString::str from SmallString::c_str, and removeDaniel Dunbar2009-08-19
| | | | | | | SmallString::c_str. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79456 91177308-0d34-0410-b5e6-96231b3b80d8
* Change raw_svector_ostream to reserve the input buffer if necessary, Ted wasDaniel Dunbar2009-08-19
| | | | | | | | | | | | | | right. - This class turns out to be much more convenient to use if we do this; clients can make sure the buffer is always big enough if they care (since our current idiom tends to be to use a SmallString<256> for the input to this we should generally be avoiding an unnecessary malloc). Also, add a convenience raw_svector_ostream::str method which flushes the buffer and returns a StringRef for the vector contents. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79446 91177308-0d34-0410-b5e6-96231b3b80d8

* Switch raw_svector_ostream to use the vector as the ostream buffer.Daniel Dunbar2009-08-19
| | | | | | | | - This avoids unnecessary malloc/free overhead in the common case, and unnecessary copying from the ostream buffer into the output vector. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79434 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
