1997-01-24 * configure: Remove Make-common.in from dependencies. (Actually inStu Grossman8-8/+8
../common/aclocal.m4).
1997-01-24 * aclocal.m4: Remove Make-common.in from dependencies.Stu Grossman2-1/+3
1997-01-23 * configure configure.in Makefile.in: Update to new configureStu Grossman32-1269/+10379
scheme which is more compatible with WinGDB builds. * configure.in: Improve comment on how to run autoconf. * configure: Re-run autoconf to get new ../common/aclocal.m4. * Makefile.in: Use autoconf substitution to install common makefile fragment.
1997-01-23 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.inStu Grossman2-0/+328
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.
1997-01-23 * configure configure.in: Don't configure common anymore. FilesStu Grossman3-87/+256
from common are now built in the individual simualtor directories. This fixes problems with the WinGDB build procedure.

(build_endian_shift): Don't check proc64. (build_instruction): Always set memval to uword64. Cast op2 to uword64 when shifting it left in memory instructions. Always use the same code for stores--don't special case proc64.
