2011-03-18raw_ostream: [PR6745] Tweak formatting (double)%e for Windows hosts.NAKAMURA Takumi
On MSVCRT and compatible, output of %e is incompatible to Posix by default. Number of exponent digits should be at least 2. "%+03d" FIXME: Implement our formatter in future! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127872 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-16lib/Support/raw_ostream.cpp: On mingw, report_fatal_error() should not be ↵NAKAMURA Takumi
called at dtor context. report_fatal_error() invokes exit(). We know report_fatal_error() might not write messages to stderr when any errors were detected on FD == 2. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127726 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-04raw_ostream: while it is generally desirable to do larger writes, it can lead toBenjamin Kramer
inefficient file system buffering if the writes are not a multiple of the desired buffer size. Avoid this by limiting the large write to a multiple of the buffer size and copying the remainder into the buffer. Thanks to Dan for pointing this out. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127026 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-04raw_ostream: If writing a string that is larger than the buffer, write it ↵Benjamin Kramer
directly instead of doing many buffer-sized writes. This caps the number of write(2) calls per string to a maximum of 2. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127010 91177308-0d34-0410-b5e6-96231b3b80d8

setmode is provided by io.h on Cygwin. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@116784 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-14Always use binary mode for output stream. This is important to prevent ↵Francois Pichet
unwanted end of line conversion on Windows. Should not affect Unix where O_BINARY is not defined. This fix /clang/test/lexer/preamble.c XFAIL on WIN32. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@116509 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-07Move tool_output_file into its own file.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@115973 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-01Make tool_output_file's raw_ostream instance a member variable insteadDan Gohman
of a base class. This makes it possible to unregister the file from FilesToRemove when the file is done. Also, this eliminates the need for formatted_tool_output_file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112706 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-20Make outs() close its file when its stream is destructed, so thatDan Gohman
pending output errors are detected. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111643 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-20Delete raw_stdout_ostream and raw_stderr_ostream, which are unusedDan Gohman
outside of outs() and errs() themselves, and they don't really need custom classes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111642 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-20Move raw_ostream's Error flag into raw_fd_ostream, as that's the onlyDan Gohman
class which is using it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111639 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-20Introduce a new tool_output_file class, which extends raw_ostream withDan Gohman
functionality that most command-line tools need: ensuring that the output file gets deleted if the tool is interrupted or encounters an error. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111595 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-18Make raw_fd_ostream consider itself the owner of STDOUT_FILENO whenDan Gohman
constructed with an output filename of "-". In particular, allow the file descriptor to be closed, and close the file descriptor in the destructor if it hasn't been explicitly closed already, to ensure that any write errors are detected. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111436 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-18Revert r111321. This doesn't fix a problem.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111339 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-17Fix the rest of rdar://8318441 which happens when a raw_fd_ostreamChris Lattner
(e.g. errs()) fails in close() due to (e.g.) a broken pipe. As previously written, the had_error() flag would get set and then the raw_ostream dtor would report a fatal error. There is nothing the client can do about this and we have no way to report the error, so just eat it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111321 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-19Make some methods const. The only interesting change here is thatChris Lattner
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

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

2009-08-24raw_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

2009-08-23Change 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
