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

26 * Make-common.in (CGEN): Load guile.scm, and include a trailing
27 '-s' argument.

31 arguments are expanded.
32 (cgen.sh): Be prepared for the 'cgen' argument to contain spaces.
33 (arch, cpu, decode, cpu-decode, defs, desc): Place the name of the
34 application Scheme script directly after ${cgen}; don't precede it
35 with a -s.

5058
5059 * aclocal.m4 (COMMON_MAKEFILE_FRAG): Quote a couple of $'s in
5060 comments and single quotes. Fixes a problem found on hpux.
5061
5062Thu Jan 23 13:35:03 1997 Stu Grossman (grossman@critters.cygnus.com)
5063
5064 * aclocal.m4: Remove Make-common.in from dependencies.
5065 * (distclean): Remove targ-vals.def.
5066
5067 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in
5068 into here. Makes insertion into makefiles easier. Also, change
5069 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
5070 targ-map.o, and run are built. They are now built in the
5071 individual simulator directories, taking sources from ../common as
5072 necessary. This replaces the merging of libcommon.a into
5073 linsim.a, which was problematic for the WinGDB build process.
5074 * run.c: Include config.h from . instead of ../common.
5075 * Make-common.in: Remove. It's no longer necessary.

5147
5148 * run.c (main): Removed SH specific comments, so source is
