7476
7477         * Makefile.in (libcommon.a): Delete.
7478         (callback.o,targ-map.o): Delete, moved to Make-common.in.
7479         (gentmap,targ-vals.h,targ-map.c): Likewise.
7480         (run-autoconf): Delete.
7481         * aclocal.m4 (SIM_AC_OUTPUT): Redo creation of Makefile.
7482         (common makefile fragment): Moved back into ...
7483         * Make-common.in: Resurrect.
7484         * configure.in (AC_LINK_FILES): Delete, unnecessary now.
7485         * configure: Regenerated.

7487 Fri Jan 31 07:16:49 1997  Doug Evans  <dje@canuck.cygnus.com>
7488
7489         * aclocal.m4 (SIM_AC_COMMON): Move COMMON_MAKEFILE_FRAG from here.
7490         (SIM_AC_OUTPUT): To here.
7491
7492 Fri Jan 24 10:37:17 1997  Stu Grossman  (grossman@critters.cygnus.com)
7493
7494         * aclocal.m4 (COMMON_MAKEFILE_FRAG):  Quote a couple of $'s in
7495         comments and single quotes.  Fixes a problem found on hpux.
7496
7497 Thu Jan 23 13:35:03 1997  Stu Grossman  (grossman@critters.cygnus.com)
7498
7499         * aclocal.m4:  Remove Make-common.in from dependencies.
7500         * (distclean):  Remove targ-vals.def.
7501
7502         * aclocal.m4 (SIM_AC_COMMON):  Move contents of Make-common.in
7503         into here.  Makes insertion into makefiles easier.  Also, change
7504         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
7505         targ-map.o, and run are built.  They are now built in the
7506         individual simulator directories, taking sources from ../common as
7507         necessary.  This replaces the merging of libcommon.a into
7508         linsim.a, which was problematic for the WinGDB build process.
7509         * run.c:  Include config.h from . instead of ../common.
7510         * Make-common.in:  Remove.  It's no longer necessary.

7526
7527 Mon Nov 25 19:44:35 1996  Doug Evans  <dje@canuck.cygnus.com>
7528
7529         * Make-common.in (Makefile): Set CONFIG_HEADERS="".
7530         * aclocal.m4: Mark the fact that --enable-sim-bswap isn't host
7531         specific.
7532         (SIM_AC_OUTPUT): Don't build Makefile if CONFIG_FILES="".

7540         Only process -p/-s ifdef SIM_HAVE_PROFILE.
7541         Parse program name from argv[0] and use in error messages.
7542         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
7543         Add support for incomplete h8/300 termination indicators.
7544         (usage): Make more verbose.
7545         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.
7546         * Makefile.in,Make-common.in,callback.c: New files.

7564         * run.c (exec_bfd): Rename from sim_bfd, to use the gdb name.
7565         (main): Ditto.

7582
7583         * run.c (main): Removed SH specific comments, so source is
7584         generic. Also updated to only load relevant sections. Moved
7585         sim_open() to after callback attach (to match GDB).
