2009-12-14Micro-optimize these functions in the case where they are not inlined.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@91316 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-17Add raw_ostream::write_escaped, for writing escaped strings.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84355 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-15Drop the raw_ostream required buffer size to 1.Daniel Dunbar
- As best I can tell, we have eliminated all the code which used to require a larger buffer size. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81912 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-11Fix llvm-extract's "writing bitcode to a terminal" warning, which wasn'tDan Gohman
working. To support this, add an is_displayed() function to raw_ostream, and generalize Process::StandardOutIsDisplayed and friends in order to support it. Also, call RemoveFileOnSignal before creating a file instead of after, so that the file isn't left behind if the program is interrupted between when the file is created and RemoveFileOnSignal is called. While here, add a -S to llvm-extract and port it to IRReader so that it supports assembly input. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81568 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-25Make LLVM command-line tools overwrite their output files without -f.Dan Gohman
This is conventional command-line tool behavior. -f now just means "enable binary output on terminals". Add a -f option to llvm-extract and llvm-link, for consistency. Remove F_Force from raw_fd_ostream and enable overwriting and truncating by default. Introduce an F_Excl flag to permit users to enable a failure when the file already exists. This flag is currently unused. Update Makefiles and documentation accordingly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79990 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-24Correctly account for the Spaces array nul terminator. Thanks Chris!Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79894 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-24raw_ostream::indent is used for PadToColumn which often prints moreDan Gohman
than 16 spaces. Make the Spaces array wide enough to handle common cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79890 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-24split raw_os_ostream out to its own header and implementation file. ThisChris Lattner
means that raw_ostream no longer has to #include <iosfwd>. Nothing in llvm should use raw_os_ostream.h, but llvm-gcc and some unit tests do. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79886 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-24prune the #includes in raw_ostream.h by moving a Chris Lattner
member out of line. ftostr is not particularly speedy, so that method is presumably not perf sensitive. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79885 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-23Fix off-by-one in llvm::Format::print.Daniel Dunbar
- This also shortens the Format.h implementation, and uses the print buffer fully (it was wasting a character). - This manifested as llvm-test failures, because one side effect was that raw_ostream would write garbage '\x00' values into the output stream if it happened that the string was at the end of the buffer. This meant that grep would report 'Binary file matches', which meant the silly pattern matching llvm-test eventually does would fail. Cute. :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79862 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-23Fix windows build.Benjamin Kramer
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79845 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-23Change raw_fd_ostream to take flags as an optional bitmask Chris Lattner
instead of as two bools. Use this to add a F_Append flag which has the obvious behavior. Other unrelated changes conflated into this patch: 1. REmove EH stuff from llvm-dis and llvm-as, the try blocks are dead. 2. Simplify the filename inference code in llvm-as/llvm-dis, because raw_fd_ostream does the right thing with '-'. 3. Switch machine verifier to use raw_ostream instead of ostream (Which is the thing that needed append in the first place). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79807 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-22add a raw_ostream::indent method, to be used like:Chris Lattner
OS.indent(i) << "whatever"; people seem to like indenting things ;-) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79784 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-19Change raw_svector_ostream to reserve the input buffer if necessary, Ted wasDaniel Dunbar
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
2009-08-19Switch raw_svector_ostream to use the vector as the ostream buffer.Daniel Dunbar
- 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
2009-08-19Speculatively revert r79375, which may be breaking bootstrap, although in aDaniel Dunbar
rather obscure way (the other candidate is r79377). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79426 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-19raw_ostream: Simplify write(unsigned char) to match write(const char*, ↵Daniel Dunbar
unsigned). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79386 91177308-0d34-0410-b5e6-96231b3b80d8
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

buffer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79382 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-18Speed up raw_ostream::<<(unsigned long long) for 32-bit systems by doing mostDaniel Dunbar
div/mods in 32-bits. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79375 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-18Fix a bug in raw_ostream::write(char) introduced by the change toDan Gohman
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79362 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
2009-08-15Mingw also doesn't have st_blksize.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79142 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-15Always check to see if raw_fd_ostream's file descriptor is attached toDan Gohman
a terminal, not just when it's STDOUT_FILENO. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79066 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-13When standard output is a terminal, set outs() to be unbuffered, toDan Gohman
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78953 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-13Fix a compiler warning about comparing signed with unsigned.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78933 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-13Add an assert to check copy_to_buffer's precondition.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78926 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

2009-08-13Fix 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

2009-07-29raw_ostream: Follow the 32-bit path when printing "small" decimal numbers.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77444 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
2009-07-27Add an assertion check to raw_ostream's destructor to verifyDan Gohman
that the subclass hasn't left any pending data in the buffer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77245 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

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
2009-07-15Add 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

2009-07-15Use 0664 instead of 0644 for the default open mode. This isDan Gohman
consistent with common std::ostream implmentations, and it gives the user the option of using the umask group write bit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75792 91177308-0d34-0410-b5e6-96231b3b80d8
