3 * aclocal.m4 (SIM_AC_OPTION_WARNINGS): Don't include
4 -Wuninitialized in the default list of build warnings if CFLAGS is

22 (arch, cpu, decode, cpu-decode, defs, desc): Place the name of the
23 application Scheme script directly after ${cgen}; don't precede it
24 with a -s.

5047
5048 * aclocal.m4 (COMMON_MAKEFILE_FRAG): Quote a couple of $'s in
5049 comments and single quotes. Fixes a problem found on hpux.
5050
5051Thu Jan 23 13:35:03 1997 Stu Grossman (grossman@critters.cygnus.com)
5052
5053 * aclocal.m4: Remove Make-common.in from dependencies.
5054 * (distclean): Remove targ-vals.def.
5055
5056 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in
5057 into here. Makes insertion into makefiles easier. Also, change
5058 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
5059 targ-map.o, and run are built. They are now built in the
5060 individual simulator directories, taking sources from ../common as
5061 necessary. This replaces the merging of libcommon.a into
5062 linsim.a, which was problematic for the WinGDB build process.
5063 * run.c: Include config.h from . instead of ../common.
5064 * Make-common.in: Remove. It's no longer necessary.
5065

5083 * Make-common.in (Makefile): Set CONFIG_HEADERS="".
5084 * aclocal.m4: Mark the fact that --enable-sim-bswap isn't host
5085 specific.
5086 (SIM_AC_OUTPUT): Don't build Makefile if CONFIG_FILES="".

5104
5105 * run.c: Include stdarg.h if __STDC__.
5106
5107Tue Oct 15 11:16:31 1996 Jeffrey A Law (law@cygnus.com)
5108
5109 * run.c (main): Don't print out anything if the signal
5110 number is zero (ie no signal).

5136
5137 * run.c (main): Removed SH specific comments, so source is
