* Switch to SmallString::str from SmallString::c_str, and removeDaniel Dunbar2009-08-192-5/+6
| | | | | | SmallString::c_str. llvm-svn: 79456
* Change raw_svector_ostream to reserve the input buffer if necessary, Ted wasDaniel Dunbar2009-08-191-3/+7
| | | | | | | | | | | | | 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. llvm-svn: 79446
* Switch Twine::str() to use toVector(), which is now efficient.Daniel Dunbar2009-08-191-14/+4
| | | | llvm-svn: 79437
* Switch raw_svector_ostream to use the vector as the ostream buffer.Daniel Dunbar2009-08-191-1/+29
| | | | | | | - This avoids unnecessary malloc/free overhead in the common case, and unnecessary copying from the ostream buffer into the output vector. llvm-svn: 79434
* Speculatively revert r79375, which may be breaking bootstrap, although in aDaniel Dunbar2009-08-191-15/+10

* raw_ostream: Reduce FormattedStream's reliance on raw_ostream's implementation.Daniel Dunbar2009-08-181-21/+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. llvm-svn: 79379

* Fix a bug in raw_ostream::write(char) introduced by the change toDan Gohman2009-08-181-3/+10
| | | | | | | | | allow underlying stream classes to decline buffering. After calling SetBuffered(), re-check whether the stream is Unbuffered in order to handle the case where the underlying stream has declined buffering. llvm-svn: 79362

* Add Triple matching for pic16 arch and solaris OS.Daniel Dunbar2009-08-181-2/+8
| | | | | | - Patch by Yonggang Luo. llvm-svn: 79314
* the MinPad argument to PadToColumn only really makes sense to be 1,Chris Lattner2009-08-171-4/+3

* Modify APFloat to take a StringRef instead of a c string.Erick Tryzelaar2009-08-161-63/+106
| | | | | | | This also adds unit tests to APFloat that mainly tests the string handling of APFloat, but not much else of it's api. llvm-svn: 79210

| | | | | | | | mimic the behavior of stdtout, which is line-buffered when the output is a terminal. This fixes some issues with bugpoint output appearing being printed out of order. llvm-svn: 78953
* Fix a compiler warning about comparing signed with unsigned.Dan Gohman2009-08-131-1/+1

* Set raw_os_ostream, raw_string_ostream, and raw_svector_ostream to beDan Gohman2009-08-131-12/+0
| | | | | | | | unbuffered. std::ostream does its own buffering, and std::string and SmallVector both have allocation strategies intended to handle frequent appending. llvm-svn: 78924
* Add support to raw_ostream for sizing the buffer according to theDan Gohman2009-08-131-2/+25
| | | | | | | needs of the underlying output mechanism. raw_fd_ostream now uses st_blksize from fstat to determine a buffer size. llvm-svn: 78923

* Convert APint::{fromString,APInt,getBitsNeeded} to use StringRef.Daniel Dunbar2009-08-131-17/+22
| | | | | | - Patch by Erick Tryzelaar, with some edits (and a bug fix) from me. llvm-svn: 78885

| | | | | | | | when !isSingleWord() but getActiveBits() is small, we were using the pointer value instead of the low word of the integer value. llvm-svn: 78821
