devbufalign. (class fhandler_dev_floppy): Remove member bytes_per_sector; * fhandler_floppy.cc (bytes_per_sector): Define as devbufalign. (fhandler_dev_floppy::open): Set devbufalign to a multiple of the sector size and handle devbuf allocation and alignment in !O_DIRECT case here. Change comment accordingly. Call FSCTL_ALLOW_EXTENDED_DASD_IO for partitions as well. (fhandler_dev_floppy::raw_write): Fix comment. Rewrite and fix writing behaviour when application uses read and lseek. (fhandler_dev_floppy::lseek): Use rounddown macro. Call SetFilePointerEx rather than the old SetFilePointer. (fhandler_dev_floppy::ioctl): Reformat switch. Call IOCTL_DISK_UPDATE_PROPERTIES rather than IOCTL_DISK_UPDATE_DRIVE_SIZE in BLKRRPART case. Support BLKIOMIN, BLKIOOPT, BLKPBSZGET and BLKALIGNOFF. * fhandler_raw.cc (fhandler_dev_raw::fhandler_dev_raw): Initialize all devbuf-related members. (fhandler_dev_raw::~fhandler_dev_raw): Delete devbufalloc rather than devbuf. (fhandler_dev_raw::open): Drop allocating devbuf. (fhandler_dev_raw::dup): Allocate devbufalloc and set devbuf to support new sector-aligned devbuf handling. (fhandler_dev_raw::fixup_after_exec): Ditto. * fhandler_tape.cc (fhandler_dev_tape::open): Ditto, set devbufalign to 1. * include/cygwin/fs.h (BLKIOMIN): Define. (BLKIOOPT): Define. (BLKALIGNOFF): Define. (BLKPBSZGET): Define.
README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
