This was tickled by a Clang diagnostic; Clang test case to follow.

Add static cast to unsigned char whenever a character classification function is called with a signed char argument, in order to avoid assertions in Windows Debug configuration.

Sooooo many of these had incorrect or strange main module includes.
I have manually inspected all of these, and fixed the main module
include to be the nearest plausible thing I could find. If you own or
care about any of these source files, I encourage you to take some time
and check that these edits were sensible. I can't have broken anything
(I strictly added headers, and reordered them, never removed), but they
may not be the headers you'd really like to identify as containing the
API being implemented.

Many forward declarations and missing includes were added to a header
files to allow them to parse cleanly when included first. The main
module rule does in fact have its merits. =]

non-deterministic crash in the test suite. Fixes PR10055!

On MSVCRT and compatible, output of %e is incompatible to Posix by default. Number of exponent digits should be at least 2. "%+03d"

report_fatal_error() invokes exit(). We know report_fatal_error() might not write messages to stderr when any errors were detected on FD == 2.

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.

llvm-svn: 127026

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.

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.

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.

functionality that most command-line tools need: ensuring that the
output file gets deleted if the tool is interrupted or encounters an
error.

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.

(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.

Also, fix the build on systems which don't define EWOULDBLOCK.

llvm-svn: 103158

EAGAIN and EWOULDBLOCK are used here.

Also, handle the case where a write call is interrupted after
some data has already been written.

This should fix mysteriously crashing boost regression tests when stderr is
managed by bjam (PR7043).
