Bring back the `config file in the kernel' feature from the 1.x days. This is conditionalized by the INCLUDE_CONFIG_FILE option in your kernel config file and is not turned on by default. Submitted-By: Bill Pechter <pechter@shell.monmouth.com>

Make the necessary changes so that an ELF kernel can be built. I have successfully built, booted, and run a number of different ELF kernel configurations, including GENERIC. LINT also builds and links cleanly, though I have not tried to boot it. The impact on developers is virtually nil, except for two things. All linker sets that might possibly be present in the kernel must be listed in "sys/i386/i386/setdefs.h". And all C symbols that are also referenced from assembly language code must be listed in "sys/i386/include/asnames.h". It so happens that failure to do these things will have no impact on the a.out kernel. But it will break the build of the ELF kernel. The ELF bootloader works, but it is not ready to commit quite yet.

BINFORMAT?= aout
This is the kernel linker. To use it, you will first need to apply the patches in freefall:/home/dfr/ld.diffs to your ld sources and set BINFORMAT to aoutkld when linking the kernel. Library changes and userland utilities will appear in a later commit.

Change all #includes to follow the current Berkeley style. Some of these ``changes'' are actually not changes at all, but CVS sometimes has trouble telling the difference. This also includes support for second-directory compiles. This is not quite complete yet, as `config' doesn't yet do the right thing. You can still make it work trivially, however, by doing the following: rm /sys/compile mkdir /usr/obj/sys/compile ln -s M-. /sys/compile cd /sys/i386/conf config MYKERNEL cd ../../compile/MYKERNEL ln -s /sys @ rm machine ln -s @/i386/include machine make depend make

Go back to -O optimization...Bruce's arguments against -O2 are convincing enough for me.

COPTFLAGS?=-O
Added -I- to ${INCLUDES}. This makes 4.4Lite's (mis?)use of "foo.h" for headers in the compile directory work unsurprisingly. Without -I-, the search for "foo.h" begins in the directory of the file that includes it, and the compile directory is only searched because `-I.' is in ${INCLUDES}. Removed -I$S/sys from ${INCLUDES}. It was once necessary to find things like "param.h" in $S/sys. Now <sys/param.h> is found in $S.

Create a special option file "opt_global.h" which is included by all source files via a 'cc -include opt_global.h ...' type arrangement. This means we can untangle certain header files. options.i386 has a placeholder until it has a real member so we can avoid having to teach config about it just yet. Reviewed by: bde

LOAD_ADDRESS?= F0100000
Moved nonstandard compiler profiling options out of config. Just print the profiling level in config and decide what to do in makefiles. Makefile.i386: Align functions to 16-byte boundaries if profiling is enabled. This will allow a fourfold reduction in the size of the profiling buffers.

Remove exception.o, swtch.o, support.o, conf.o and machdep.o from SYSTEM_OBS. They are now normal objects. Remove stale dependencies for the above now-normal objects and for locore.o and generate dependencies using mkdep. Config doesn't generate lists of assembler source files so the lists to be mkdep'ed have to be given explictly. Only the standard *.s files are given, so the dependencies for gnu/fpemul/*.s are incomplete. *.S files would be handled right if config put them in CFILES. Don't define NPX. It was replaced by NNPX > 0 years ago. Define LOAD_ADDRESS in COPTS so that compiling machdep.c isn't a special case. Moving around the dependencies exposed a bug in make.

Never strip the kernel. Recommend -Wimplicit in CWARNFLAGS next. There are still a few hundred potential arg mismatches because no function declaration is in scope. Don't duplicate option `-I.'. Remove null editing of the assembler source for all profiled objects. The required magic has been done since prehistoric times by an asm("mcount") declaration. Simplify the clean rule. Don't try to be clever about timestamps involving genassym. genassym's timestamp usually got ahead of assym.s's timestamp, so `make' almost always had to run genassym and compare *assym.s to decide that nothing needed to be done. The cost is reassembling a few files whenever genassym is rebuilt. Assembling is almost as fast as comparing. Always go through genassym.o to build genassym. This would have avoided numerous bugs involving mkdep -p. Now it just stops genassym from depending on the name of the temporary object file. Use ${CFLAGS} for building genassym. Mainly ${CWARNFLAGS} were missing.

This commit affects ELF kernels only. Remove "setdefs.h" and arrange to generate it automatically at ELF kernel build time. "gensetdefs.c" is a utility which scans a set of ELF object files and outputs a line ``DEFINE_SET(name, length);'' for each linker set that it finds. When generating an ELF kernel, this is run just before the final link to generate "setdefs.h". Remove the init_sets() function from "setdef0.c", and its call from "machdep.c". Since "gensetdefs.c" calculates the length of each set, it is no longer necessary in an ELF kernel to count the set elements at kernel initialization time. Also remove "set_of_sets" which was used for this purpose. Link "setdef0" and "setdef1" into the kernel only if building for ELF. Since init_sets() is no longer used, there is no need to link them into an a.out kernel.

Don't use them yet. bootinfo.h: Add a size field so that we can resolve some mismatches between the loader bootinfo and the kernel boot info. The version number is not so good for this because of historical botches and because it's harder to maintain. Add memory size and symbol table fields. Change the names of everything. Hacks to save a few bytes: asm.S, boot.c, boot2.S: Replace `ouraddr' by `(BOOTSEG << 4)'. boot.c: Don't statically initialize `loadflags' to 0.

Make the necessary changes so that an ELF kernel can be built. I have successfully built, booted, and run a number of different ELF kernel configurations, including GENERIC. LINT also builds and links cleanly, though I have not tried to boot it. The impact on developers is virtually nil, except for two things. All linker sets that might possibly be present in the kernel must be listed in "sys/i386/i386/setdefs.h". And all C symbols that are also referenced from assembly language code must be listed in "sys/i386/include/asnames.h". It so happens that failure to do these things will have no impact on the a.out kernel. But it will break the build of the ELF kernel. The ELF bootloader works, but it is not ready to commit quite yet.

"gensetdefs.c" is a utility which scans a set of ELF object files and outputs a line ``DEFINE_SET(name, length);'' for each linker set that it finds. When generating an ELF kernel, this is run just before the final link to generate "setdefs.h". Remove the init_sets() function from "setdef0.c", and its call from "machdep.c".

Create a special option file "opt_global.h" which is included by all source files via a 'cc -include opt_global.h ...' type arrangement. This means we can untangle certain header files. options.i386 has a placeholder until it has a real member so we can avoid having to teach config about it just yet. Reviewed by: bde

${OBJS}: opt_global.h
Remove exception.o, swtch.o, support.o, conf.o and machdep.o from SYSTEM_OBS. They are now normal objects. Remove stale dependencies for the above now-normal objects and for locore.o and generate dependencies using mkdep. Config doesn't generate lists of assembler source files so the lists to be mkdep'ed have to be given explictly. Only the standard *.s files are given, so the dependencies for gnu/fpemul/*.s are incomplete. *.S files would be handled right if config put them in CFILES. Don't define NPX. It was replaced by NNPX > 0 years ago. Define LOAD_ADDRESS in COPTS so that compiling machdep.c isn't a special case. Moving around the dependencies exposed a bug in make. It doesn't know that assym.s and ./assym.s are the same. Add a rule tell it.

Make the necessary changes so that an ELF kernel can be built. I have successfully built, booted, and run a number of different ELF kernel configurations, including GENERIC. LINT also builds and links cleanly, though I have not tried to boot it. The impact on developers is virtually nil, except for two things. All linker sets that might possibly be present in the kernel must be listed in "sys/i386/i386/setdefs.h". And all C symbols that are also referenced from assembly language code must be listed in "sys/i386/include/asnames.h". It so happens that failure to do these things will have no impact on the a.out kernel. But it will break the build of the ELF kernel. The ELF bootloader works, but it is not ready to commit quite yet.

Don't include options MULTICAST or MROUTING in generic kernels. MULTICAST has no effect now, and MROUTING should never be defined by default. (Eventually the code should be dynamically loadable.) Also, allow for Pentium CPUs in GENERICBT kernels. Add an `install' rule to Makefile.i386, which looks like this: mv /kernel /kernel.old install -c -m 555 -o root -g root -fschg kernel / I'd like comments on whether or not you think it's a good idea to have the kernel be immutable by default; I'm happy either way.
