2013-XX-XX
Version 1.5
* Emit `X_server_routine' functions that can be inlined reducing the
message dispatch overhead.
* Improve support for variable-sized c strings.
* Fix a warning when compiling generated files.
2013-09-27
Version 1.4
* Don't accept the `-R' (msg_send) command line option anymore and make the
`-r' one (msg_rpc) a no-op.
* Fix warnings when compiling generated files with recent versions of GCC.
* Handle the preprocessor option `-isystem' correctly.
* Cope with command line arguments that contain whitespace.
* Make the installation tree relocatable.
* Be more careful to catch write errors when closing files.
* Spurious deallocation of out-of-line memory has been fixed in case of an
error while processing the RPC.
2002-08-29
Version 1.3.1
* Fix warnings when compiling generated files with GCC 3.x.
* Fix alignment issues for greater than 32 bit types on 32 bit
machines.
* Alpha fixes.
2002-03-08
Version 1.3
* Minor bug fixes.
* The new keyword `retcode' is accepted as a parameter modifier.
This does not do anything, but is accepted for compatibility
with the MIG input syntax used with OSF Mach.
* The debian/ subdirectory of packaging files is now included in the
MIG source distribution.
2001-07-07
Version 1.2
* New option -n to suppress default output file creation.
With -n, no output files are created except those named
by other command-line options.
* New option -list to generate a file listing RPC names and message ID numbers.
The output is in six columns:
subsystem-name subsystem-base rpc-name rpc-num msg-id reply-id
For example this output line:
io 21000 io_read 1 21001 21101
says that the file used `subsystem io 21000' and defined an RPC called
`io_read' with message ID 21000+1 = 21001; the reply message ID is
computed 21001+100 = 21101. In this example:
io 21000 io_reauthenticate 14 21014 0
the declaration is a `simpleroutine' that expects no reply, so 0 is
printed in place of the computed reply message ID. The output list
these examples is generated on a GNU/Hurd system with this command:
mig -n -list /dev/stdout /include/hurd/io.defs
* Output files of C source now start by defining _GNU_SOURCE,
for compatibility with the GNU C library on GNU/Hurd.
1999-06-22
Version 1.1
* First official net release.
1999-05-23
Version 1.0.2
* Understand normal GNU --version and --help args.
* Find CPP in a more flexible fashion.
1998-12-04
Version 1.0.1
* This release fixes a bug in the `mig' driver script that made it fail to
invoke the C preprocessor properly.
1998-08-19
Version 1.0
* MIG has been split into a separate distribution to make it easier to set
up a compilation environment for GNU Mach and Hurd systems. The mig
program itself in this distribution has not been substantively changed
from the version in the GNUmach 1.1.3 distribution.
