Those names are not generally applicable. Thu Feb 27 10:17:23 1997 Andrew Cagney * sim-bits.c, sim-bits-n.h (new): Split sim-bits.c into two parts in a fashion similar to sim-endian-n. * sim-endian.h: (H_word, L_word, AL_*, VL_*): Extend to include both value and address macro's. Tue Feb 25 18:51:57 1997 Andrew Cagney * sim-alu.h (ALU16_BEGIN, ALU16_SET, ...): Fill in. * sim-endian.h (L_word, H_word): Replace MS2W_4, LS2W_4 with more generic L_word, H_word macro's.

Tue Feb 11 13:46:49 1997 Michael Meissner * callback.c: If HAVE_CONFIG_H is defined, include config.h from autoconf. If HAVE_UNISTD_H is defined, include unistd.h to get appropriate definitions of read, write, etc. Add prototype for system. Tue Feb 4 13:24:44 1997 Doug Evans * Makefile.in (libcommon.a): Delete. (callback.o,targ-map.o): Delete, moved to Make-common.in. (gentmap,targ-vals.h,targ-map.c): Likewise. (run-autoconf): Delete. * aclocal.m4 (SIM_AC_OUTPUT): Redo creation of Makefile. (common makefile fragment): Moved back into ... * Make-common.in: Resurrect. * configure.in (AC_LINK_FILES): Delete, unnecessary now. * configure: Regenerated. Fri Jan 31 07:16:49 1997 Doug Evans * aclocal.m4 (SIM_AC_COMMON): Move COMMON_MAKEFILE_FRAG from here. (SIM_AC_OUTPUT): To here. Fri Jan 24 10:37:17 1997 Stu Grossman (grossman@critters.cygnus.com) * aclocal.m4 (COMMON_MAKEFILE_FRAG): Quote a couple of $'s in comments and single quotes. Fixes a problem found on hpux. Thu Jan 23 13:35:03 1997 Stu Grossman (grossman@critters.cygnus.com) * aclocal.m4: Remove Make-common.in from dependencies. * (distclean): Remove targ-vals.def. * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in into here. Makes insertion into makefiles easier. Also, change the way that callback.o, gentmap, targ-vals.h, targ-map.c, targ-map.o, and run are built. They are now built in the individual simulator directories, taking sources from ../common as necessary. This replaces the merging of libcommon.a into linsim.a, which was problematic for the WinGDB build process. * run.c: Include config.h from . instead of ../common. * Make-common.in: Remove. It's no longer necessary. Mon Dec 16 15:02:33 1996 Ian Lance Taylor * Make-common.in (ALL_CLAGS): Put CFLAGS at the end. (.c.o): Put $(ALL_CFLAGS) before the file being compiled. Wed Dec 11 11:30:58 1996 Jim Wilson * run.c (main): Set target_byte_order before call to sim_open. Sun Dec 8 18:22:06 1996 Doug Evans * callback.c: #include (os_error): New function.

(SIM_AC_OUTPUT): Don't build Makefile if CONFIG_FILES="". Wed Nov 20 01:11:04 1996 Doug Evans * run.c: #include ../common/config.h, tconfig.h. (myname): New static global. (main): Recognize new options -a, -c. Also recognize -h if h8/300. Only process -c ifdef SIM_HAVE_SIMCACHE. Only process -p/-s ifdef SIM_HAVE_PROFILE. Parse program name from argv[0] and use in error messages. Pass sim_args to sim_open. Pass prog_args to sim_create_inferior. Add support for incomplete h8/300 termination indicators. (usage): Make more verbose. * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files. * Makefile.in,Make-common.in,callback.c: New files. * nltvals.def,gentmap.c,gentvals.sh: New files. Tue Nov 12 13:34:00 1996 Dawn Perchik * run.c: Include stdarg.h if __STDC__. Tue Oct 15 11:16:31 1996 Jeffrey A Law (law@cygnus.com) * run.c (main): Don't print out anything if the signal number is zero (ie no signal). Tue Oct 15 11:20:44 1996 Michael Meissner * run.c (main): Print out if the program raised a signal. Wed Sep 18 09:52:14 1996 Michael Meissner * run.c (exec_bfd): Rename from sim_bfd, to use the gdb name. (main): Ditto. Tue Sep 17 11:04:50 1996 James G. Smith * run.c (main): Explicitly cast malloc() parameter. Thu Sep 12 11:27:21 1996 Michael Meissner * run.c (sim_bfd): New global to hold the bfd pointer for the executable. (main): Initialize sim_bfd. Fri Dec 15 16:27:49 1995 Ian Lance Taylor * run.c (main): Use new bfd_big_endian macro. Wed Nov 8 15:49:49 1995 James G. Smith * run.c (main): Removed SH specific comments, so source is generic. Also updated to only load relevant sections. Moved sim_open() to after callback attach (to match GDB). * run.1: Removed SH specific comments. Sat Oct 21 12:31:01 1995 Jim Wilson * run.c (main): Always return sigrc at end. Tue Oct 10 12:03:13 1995 J.T. Conklin * run.c (main): Print error diagnostic and exit if bfd_openr() or bfd_check_format() fails. Thu Sep 28 15:40:36 1995 steve chamberlain * run.c, run.1: From sh directory.
