Version 1.8 (2016-12-XX)
* A spurious warning in the generated code has been fixed.
Version 1.7 (2016-05-18)
* MIG now has a test suite. It includes a set of valid and invalid
definition files that MIG will try to process. For valid
definitions, GCC will compile the stubs to check if valid C code was
generated.
* The generated code uses integer types from <stdint.h> now instead of
the old Mach types.
* Code that was hard-coding the word size has been identified and
fixed.
* Support for the obsolete kinds of RPC routines 'functions',
'procedures', and 'simple procedures' has been removed.
* MIG now emits code that casts objects translated from capabilities
to the correct C type.
Version 1.6 (2015-10-31)
* MIG now emits RPC lookup functions that are declared `static inline'
improving compatibility with newer dialects of C.
Version 1.5 (2015-04-10)
* Add support for protected payloads. The new `intranpayload' option
can be used to specify a translation function translating payloads
to values of the translated type. This function will be used
instead of the `intran' function to to look up the receiving object
of a message in a server. This makes it easy to use the protected
payloads introduced in GNU Mach 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.
Version 1.4 (2013-09-27)
* 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.
Version 1.3.1 (2002-08-29)
* 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.
Version 1.3 (2002-03-08)
* 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.
Version 1.2 (2001-07-07)
* 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.
Version 1.1 (1999-06-22)
* First official net release.
Version 1.0.2 (1999-05-23)
* Understand normal GNU --version and --help args.
* Find CPP in a more flexible fashion.
Version 1.0.1 (1998-12-04)
* This release fixes a bug in the `mig' driver script that made it fail to
invoke the C preprocessor properly.
Version 1.0 (1998-08-19)
* 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.
