	in the line/file macros.

2019-08-22  Raphael 'kena' Poss  <knz@thaumogen.net>

	Apply the file/line patch on top of m4 1.4.18. The source archive

	up the gnulib diffs required for building on newer glib 2.28
	systems.

	* installer/patches/m4-patch-file-line.patch: New.
	* installer/rules/m4.mk: Use it.

2016-07-05  Raphael 'kena' Poss  <r.poss@uva.nl>

	Fix a logic error.

	* installer/rules/slc.mk ($(SLC_BUILD)/configure_done): Ensure
	$(REQCURRENT) is also depended here, otherwise it only gets
	created when MGSim is installed.

2016-07-05  Raphael 'kena' Poss  <r.poss@uva.nl>

	Packaging fix.

	* installer/rules/gcc5.mk (GCC5_INST_TARGETS): depend on
	`gcc5-installed-*', not `gcc-installed'.
 	* installer/rules/gcc5.mk ($(REQDIR)/.gcc5-installed-%): Generate
	`gcc5-installed', not `gcc-installed'.

2016-07-04  Raphael 'kena' Poss  <r.poss@uva.nl>

	Introduce support for LEON2-MT.

	* dist/binutilsng-dist.mk: New.
	* dist/common.mk,
	* dist/dist-common.mk: New dist target for `binutilsng'.

	* installer/configure.ac: New targets for LEON2-MT; new Makefile

	Fix the installation rules for `binutils' on recent systems.

	* installer/rules/binutils.ml: Force disable the rules that
	require `makeinfo', since .texi files in 2.18 are incompatible

	Upgrade the boostrapping rule for binutils packages.

	* dist/binutils-dist.mk: Do not force Autoconf 2.63 any more. As
	of this writing it is becoming difficult to reconfigure binutils
	2.18 using recent Autotools. So far success with AC 2.69 and AM
	1.11.6. AM 1.15 fails.

2015-07-23  Raphael 'kena' Poss  <r.poss@uva.nl>

	Fix the installation rules for `gcc' on recent systems.

	* installer/rules/gcc.mk (configure_done): Force disable the

	* installer/rules.gcc.mk (build_done): Do not restart the build
	with `LIBICONV' forced, as this is not needed any more in recent

	Improve compatibility with Autoconf 2.69.

	* installer/configure.ac: Use `$GREP' instead of `$ac_path_GREP'
	since the latter is not set any more by `AC_PROG_GREP' in recent
	Autoconf versions.

2013-01-06  Raphael 'kena' Poss  <r.poss@uva.nl>

	Fetch sources from GitHub by default when building distributable packages.

	* dist/dist-common.mk (BASE_REPO): Do it.

2013-01-06  Raphael 'kena' Poss  <r.poss@uva.nl>

	Fix `configure' for use on shells where `CDPATH' is defined.

	* installer/configure.ac: Compute the `configure' base directory
	with `CDPATH' unset.

	* installer/rules/gcc.mk,
	* installer/rules/m4.mk,
	* installer/rules/ptl.mk,
	* installer/rules/hlsimcore.mk,
	* installer/rules/slc.mk: Use `$(am__cd)' instead of `cd'
	directly, as it will reset `CDPATH'. Also use paths relative to
	`.' to avoid `CDPATH'-related resolution.

2012-11-07  Raphael 'kena' Poss  <r.poss@uva.nl>

	Packaging fix.

	* installer/configure.ac: Ensure that the subdirectory `tags' is
	created when `--with-tagfile' is used at the first invocation of
	`configure'.

2012-11-07  Raphael 'kena' Poss  <r.poss@uva.nl>

	Improve compatibility with Python 2.7.

	* installer/slenv.in: Also provision for python2.7 in PYTHONPATH.

2012-11-07  Raphael 'kena' Poss  <r.poss@uva.nl>

	* installer/rules/mgsim.mk: Adopt the MGSim standard naming of
	program names, using the target core architecture as executable
	prefix (instead of suffix as previously).

2012-11-07  Raphael 'kena' Poss  <r.poss@uva.nl>

	Minor packaging improvements.

	* installer/configure.ac: Bump requirements to the latest Autotool
	versions.
	* installer/bootstrap: Do not force Automake 1.11, since 1.12 is

	* installer/rules/hlsimcore.mk,
	* installer/rules/gcc.mk,

2011-03-07  Raphael 'kena' Poss  <r.c.poss@uva.nl>

	Protect the installation process against stray envvars.

	* installer/configure.ac: Check for variable set by `slenv'. They

	* patches/,
	* sysc/: ... here.

2011-03-06  Raphael 'kena' Poss  <r.c.poss@uva.nl>

	Do not check for alternate binary during MGSim distribution.

	* deploy/dist/mgsim-dist.mk: Remove check on configure output.

2011-03-06  Raphael 'kena' Poss  <r.c.poss@uva.nl>

	Do not require `libgnugetopt' on OS X any more.

	The latest combination of M4 / OS X does not seem to require this.

	* deploy/installer/configure.ac: Remove the tests on
	`libgnugetopt'.

2011-03-06  Raphael 'kena' Poss  <r.c.poss@uva.nl>

	Do not install SystemC any more.

	The newer version of MGSim (at this date) does not require SystemC
	for the alternate COMA implementation. Drop the requirement.

	* deploy/installer/rules/sc.mk: Remove.

	* deploy/installer/Makefile.am: Do not mention SystemC any more.

	* deploy/installer/rules/mgsim.mk: Do not fish for `include' and
	`lib' in the requirements tree.

2010-12-15  Raphael 'kena' Poss  <r.c.poss@uva.nl>

	Upgrade installer to 3.2.

	* deploy/installer/build-aux/package_version: Do it.

2010-12-14  Raphael 'kena' Poss  <r.c.poss@uva.nl>

	* deploy/installer/rules/mggcc.mk: Remove.

	* deploy/installer/rules/binutils.mk: Do not build the base
	targets any more, since the compiler now uses the `mt' targets
	always.

	* deploy/installer/rules/gcc.mk: Build the `mt' target now.

2010-12-14  Raphael 'kena' Poss  <r.c.poss@uva.nl>

	Refactor the deployment utilities as a result of the gcc/binutils cleanup.

	The custom GCC patch was recently integrated as a 'mtalpha' target
	on a dedicated Microthreaded-enabled GCC tree. This drops the
	requirement for both the µTC core compiler and the
	'alpha-linux-gnu' binutils targets. Additionally, development on
	the custom binutils was also moved to a dedicated repository.

	* deploy/dist/common.mk,
	* deploy/dist/dist-common.mk: Forget about `mggcc'.

	* deploy/dist/mggcc-dist.mk: Remove.

	* deploy/dist/dist-common.mk,
	* deploy/dist/binutils-dist.mk,
	* deploy/dist/gcc-dist.mk,
	* deploy/dist/slc-dist.mk: Fetch source from Git repositories
	instead of Subversion.

	* deploy/dist/m4-dist.mk: Use the Git hash in the source tree name
	instead of timestamps to support persistence across builds.

	* deploy/patches/gcc.patch: Remove, as this is now integrated
	in a branch on a dedicated GCC repository.
