6460         * bits.h, bits.c (SIGN_EXTEND32, SIGN_EXTEND64): New functions,
6461         sign extend a bit within a value.
6462
6463         * sim-endian.h, sim-endian-n.h (offset_N): New functions - return
6464         a pointer into the middle of a host word.
6465         * sim-endian.h (MS2W_4, LS2W_4): Use this function.

6468
6469         * callback.c: If HAVE_CONFIG_H is defined, include config.h from
6470         autoconf.  If HAVE_UNISTD_H is defined, include unistd.h to get
6471         appropriate definitions of read, write, etc.  Add prototype for
6472         system.

6477         (callback.o,targ-map.o): Delete, moved to Make-common.in.
6478         (gentmap,targ-vals.h,targ-map.c): Likewise.
6479         (run-autoconf): Delete.
6480         * aclocal.m4 (SIM_AC_OUTPUT): Redo creation of Makefile.
6481         (common makefile fragment): Moved back into ...
6482         * Make-common.in: Resurrect.

6491 Fri Jan 24 10:37:17 1997  Stu Grossman  (grossman@critters.cygnus.com)
6492
6493         * aclocal.m4 (COMMON_MAKEFILE_FRAG):  Quote a couple of $'s in

6496 Thu Jan 23 13:35:03 1997  Stu Grossman  (grossman@critters.cygnus.com)
6497
6498         * aclocal.m4:  Remove Make-common.in from dependencies.
6499         * (distclean):  Remove targ-vals.def.
6500
6501         * aclocal.m4 (SIM_AC_COMMON):  Move contents of Make-common.in
6502         into here.  Makes insertion into makefiles easier.  Also, change
6503         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
6504         targ-map.o, and run are built.  They are now built in the
6505         individual simulator directories, taking sources from ../common as
6506         necessary.  This replaces the merging of libcommon.a into
6507         linsim.a, which was problematic for the WinGDB build process.
6508         * run.c:  Include config.h from . instead of ../common.
6509         * Make-common.in:  Remove.  It's no longer necessary.

6540         Parse program name from argv[0] and use in error messages.
6541         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
6542         Add support for incomplete h8/300 termination indicators.
6543         (usage): Make more verbose.
6544         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.
