bac0d769cd raw_ostream: [PR6745] Tweak formatting (double)%e for Windows hosts. 
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!

76e68ea916 lib/Support/raw_ostream.cpp: On mingw, report_fatal_error() should not be 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.

dfb0ad30a8 raw_ostream: while it is generally desirable to do larger writes, it can lead to 
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.

acf0842088 raw_ostream: If writing a string that is larger than the buffer, write it directly instead of doing many buffer-sized writes. 
This caps the number of write(2) calls per string to a maximum of 2.

a3037c3abd Always use binary mode for output stream. This is important to prevent 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.

a2233f2801 Make tool_output_file's raw_ostream instance a member variable instead 
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.

b87ad69350 Introduce a new tool_output_file class, which extends raw_ostream with 
functionality that most command-line tools need: ensuring that the
output file gets deleted if the tool is interrupted or encounters an
error.

c825ceefb4 Make raw_fd_ostream consider itself the owner of STDOUT_FILENO when 
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.

ce3b2c3f77 Fix the rest of rdar://8318441 which happens when a raw_fd_ostream 
(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.

automatic syscall restarting is disabled.

ef969f3539 Handle EWOULDBLOCK as EAGAIN. And add a comment explaining why 
EAGAIN and EWOULDBLOCK are used here.

some data has already been written.

dd3e9aaad3 Make some methods const. The only interesting change here is that 
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.

e592923603 Fix llvm-extract's "writing bitcode to a terminal" warning, which wasn't 
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.
